    Discussion 2: Annotated Bibliography

    In each week of this course, you will research and select three (3) peer-reviewed, scholarly sources to develop an annotated bibliography that you can use in your Doctoral Study. You will need to take the three sources and synthesize the references into a single narrative annotated bibliography that compares/contrasts or supports your study. For example, you may develop three references that will fit into the Nature of the Study (or any other component) and then the synthesized version will help you in developing your Prospectus/Proposal. Please see this week’s Learning Resources for the Sample Annotated Bibliography Template, which you should use to complete your annotated bibliography.

    By Day 3

    Post your synthesized annotated bibliography narrative that includes an explanation of how these references relate to one or more components of your Doctoral Study and incorporates specific references to the Doctoral Study Rubric.

    Refer to the Week 4 Discussion 2 Rubric for specific grading elements and criteria. Your Instructor will use this rubric to assess your work.

    Important tips: Include each Article annotated bibliography have three paragraph summary, Analysis and applies to the study

    Walden's recommendations for formatting an AB includes three areas, typically formatted in three paragraphs: 

    This first paragraph of the annotation summarizes the source. It outlines the main findings and primary methods of the study.

    Summary: What did the author do? Why? What did he/she find?

    This second paragraph of the annotation analyzes the source. It explains the benefits of the source but also the limitations.

    Analysis: Was the author’s method sound? What information was missing? Is this a scholarly source?

    This third paragraph of the annotation applies the source. It explains how the source’s ideas, research, and information can be applied to other contexts.

    Application: Does this article apply to the literature? How would you be able to apply this method/study to your particular study? Is the article universal?

    In general, annotated bibliographies should avoid referring to the first or second person (I, me, my, we, our, you, and us). Instead, students should aim to be objective and remove themselves from annotations. However, there may be some exceptions to this guideline. Check with your instructor if you are unsure about whether he/she will allow you to use “I” in your annotated bibliography.

    Sample Annotated Bibliography

    Autism research continues to grapple with activities that best serve the purpose of fostering positive interpersonal relationships for children who struggle with autism. Children have benefited from therapy sessions that provide ongoing activities to aid autistic children’s ability to engage in healthy social interactions. However, less is known about how K–12 schools might implement programs for this group of individuals to provide additional opportunities for growth, or even if and how school programs would be of assistance in the end. There is a gap, then, in understanding the possibilities of implementing such programs in schools to foster the social and thus mental health of children with autism.

    Annotated Bibliography

    Kenny, M. C., Dinehart, L. H., & Winick, C. B. (2016). Child-centered play therapy for children with autism spectrum disorder. In A. A. Drewes & C. E. Schaefer (Eds.), Play therapy in middle childhood (pp. 103–147). Washington, DC: American Psychological Association.

    In this chapter, Kenny, Dinehart, and Winick provided a case study of the treatment of a 10-year-old boy diagnosed with autism spectrum disorder (ADS). Kenny et al. described the rationale and theory behind the use of child-centered play therapy (CCPT) in the treatment of a child with ASD. Specifically, children with ADS often have sociobehavioral problems that can be improved when they have a safe therapy space for expressing themselves emotionally through play that assists in their interpersonal development. The authors outlined the progress made by the patient in addressing the social and communicative impairments associated with ASD. Additionally, the authors explained the role that parents have in implementing CCPT in the patient’s treatment. Their research on the success of CCPT used qualitative data collected by observing the patient in multiple therapy sessions.

    CCPT follows research carried out by other theorists who have identified the role of play in supporting cognition and interpersonal relationships. This case study is relevant to the current conversation surrounding the emerging trend toward CCPT treatment in adolescents with ASD as it illustrates how CCPT can be successfully implemented in a therapeutic setting to improve the patient’s communication and socialization skills. However, Kenny et al. acknowledged that CCPT has limitations—children with ADS, who are not highly functioning and or are more severely emotionally underdeveloped, are likely not suited for this type of therapy.

    Kenny et al.’s explanation of this treatments’s implementation is useful for professionals in the psychology field who work with adolescents with ASD. This piece is also useful to parents of adolescents with ASD, as it discusses the role that parents can play in successfully implementing the treatment. However, more information is needed to determine if this program would be suitable as part of a K–12 school program focused on the needs of children with ASD.

    Stagmitti, K. (2016). Play therapy for school-age children with high-functioning autism. In A.A. Drewes and C. E. Schaefer (Eds.), Play therapy in middle cildhood (pp. 237–255). Washington, DC: American Psychological Association.

    Stagmitti discussed how the Learn to Play program fosters the social and personal development of children who have high functioning autism. The program is designed as a series of play sessions carried out over time, each session aiming to help children with high functioning autism learn to engage in complex play activities with their therapist and on their own. The program is beneficial for children who are 1- to 8-years old if they are already communicating with others both nonverbally and verbally. Through this program, the therapist works with autistic children by initiating play activities, helping children direct their attention to the activity, eventually helping them begin to initiate play on their own by moving past the play narrative created by the therapist and adding new, logical steps in the play scenario themselves. The underlying rationale for the program is that there is a link between the ability of children with autism to create imaginary play scenarios that are increasingly more complex and the development of emotional well-being and social skills in these children. Study results from the program have shown that the program is successful: Children have developed personal and social skills of several increment levels in a short time. While Stagmitti provided evidence that the Learn to Play program was successful, she also acknowledged that more research was needed to fully understand the long-term benefits of the program.

    Stagmitti offered an insightful overview of the program; however, her discussion was focused on children identified as having high-functioning autism, and, therefore, it is not clear if and how this program works for those not identified as high-functioning. Additionally, Stagmitti noted that the program is already initiated in some schools but did not provide discussion on whether there were differences or similarities in the success of this program in that setting.

    Although Stagmitti’s overview of the Learn to Play program was helpful for understanding the possibility for this program to be a supplementary addition in the K–12 school system, more research is needed to understand exactly how the program might be implemented, the benefits of implementation, and the drawbacks. Without this additional information, it would be difficult for a researcher to use Stigmitti’s research as a basis for changes in other programs. However, it does provide useful context and ideas that researchers can use to develop additional research programs.

    Wimpory, D. C., & Nash, S. (1999). Musical interaction therapy–Therapeutic play for children with autism. Child Language and Teaching Therapy, 15(1), 17–28. doi:10.1037/14776-014

    Wimpory and Nash provided a case study for implementing music interaction therapy as part of play therapy aimed at cultivating communication skills in infants with ASD. The researchers based their argument on films taken of play-based therapy sessions that introduced music interaction therapy. To assess the success of music play, Wimpory and Nash filmed the follow-up play-based interaction between the parent and the child. The follow-up interactions revealed that 20 months after the introduction of music play, the patient developed prolonged playful interaction with both the psychologist and the parent. The follow-up films also revealed that children initiated spontaneously pretend play during these later sessions. After the introduction of music, the patient began to develop appropriate language skills.

    Since the publication date for this case study is 1999, the results are dated. Although this technique is useful, emerging research in the field has undoubtedly changed in the time since the article was published. Wimpory and Nash wrote this article for a specific audience, including psychologists and researchers working with infants diagnosed with ASD. This focus also means that other researchers beyond these fields may not find the researcher’s findings applicable.

    This research is useful to those looking for background information on the implementation of music into play-based therapy in infants with ASD. Wimpory and Nash presented a basis for this technique and outlined its initial development. Thus, this case study can be useful in further trials when paired with more recent research.

    �The format of an annotated bibliography can change depending on the assignment and instructor preference, but the typical format for an annotated bibliography in academic writing is a list of reference entries with each entry followed by an annotation (hence the name, “annotated bibliography”).

    However, APA does not have specific rules or guidelines for annotated bibliographies, so be sure to ask your instructor for any course-specific requirements that may vary from the general format.

    �An introduction is a helpful addition to your annotated bibliography to tell your reader (a) your topic and focus for your research and (b) the general context of your topic.

    Although your assignment instructions may not explicitly ask for an introduction, your instructor might expect you to include one. If you are not sure, be sure to ask your instructor.

    �Use a Level 1 heading titled “Annotated Bibliography” or any other wording your instructor has given you to indicate to your reader that the annotations will go next and separate this section from the introduction paragraph above.

    �Format your reference entries per APA, as well as follow APA style when writing your paragraphs. However, as mentioned above, this is the extent of the formatting requirements APA has for annotated bibliographies.

    The content of the paragraphs and how many paragraphs you include in each annotation follows academic writing conventions, your assignment guidelines, and your instructor preferences.

    �This first paragraph of the annotation summarizes the source. It outlines the main findings and primary methods of the study.

    �This second paragraph of the annotation analyzes the source. It explains the benefits of the source but also the limitations.

    �This third paragraph of the annotation applies the source. It explains how the source’s ideas, research, and information can be applied to other contexts.

    AbstractPurpose – The paper seeks to discuss and develop SCM as a scientific discipline using different theories from non-logistics areas to explain inter-organizational phenomena. It also attempts to establish a frame of reference that allows us to mitigate the gap between the current SCM research andpractice and the theoretical explanations of how to structure and manage supply chains.Design/methodology/approach – The paper introduces three different perspectives that together will contribute to a broader understanding of SCMin practice: an economic perspective; a socio-economic perspective; and a strategic perspective. The theoretical framework is applied to two importantresearch topics within SCM: third party logistics (TPL); and new product development (NPD).Findings – There is no such thing as “a unified theory of SCM”. Depending on the concrete situation, one can choose one theory as the dominantexplanatory theory, and then complement it with one or several of the other theoretical perspectives.Research limitations/implications – The way the four theories complement one another is explored on a conceptual basis, but further research intothis direction may explore more deeply how these alleged complementarities occur in practice, and how managers mould their decisions by these ideas.Practical implications – The four theories can provide normative support to important management decisions in supply chains, such as outsourcing,safeguards against opportunism, and alignment of incentives.Originality/value – The main contribution is that one cannot rely on one theoretical explanation when analyzing phenomena in SCM. It is neccessaryto consider several theories and how they may complement one another in order to provide a more comprehensive view of SCM.

    1. Introduction

    1.1 Starting-point of considerations

    The practical field of supply chain management (SCM) is

    constantly changing, as the competitiveness of international

    companies is more and more dependent on their capability to

    produce and deliver customized products and services fast

    and efficiently all over the world. At the same time, an

    increasing percentage of the value creation takes place outside

    the boundaries of the individual firm (see, for example, Bruce

    et al., 2004). This induces higher complexity and diversity

    into management decisions regarding the structure of the

    operations, the positioning of activities and processes, the role

    and power of the participants, and the most efficient forms of

    collaboration between all members in a transformation chain

    between production and consumption, which we call a supply

    chain. These issues also impact on research in the field of

    operations management. In order to understand and to

    explain decision-making and practices in a complex network

    of collaborating firms (see also Rudberg and Olhager, 2003),

    we need to draw on several behavioral and organizational

    theories and frameworks in combination. Our approach is

    therefore important, as this coupling of organizational

    theories with SCM is not often discussed within the

    audience of this journal.Lamming (1996) introduces the theory of SCM as an

    extension of logistics, though referring to the extended need

    of relationship issues to be considered in the theory of SCM.

    However, the notions still remain on a more applied than

    theory-building level. Larson and Halldorsson (2004) discuss

    four unique perspectives on the relationship between logistics

    and SCM. Tan et al. (1999, 2002), as well as Akkermans et al.

    (1999), recognize the customer orientation as one important

    ingredient as well as the simultaneous integration of

    upstream, downstream and internal performance systems.

    Also here we can identify implicitly an organization’s

    behavioral backbone, which is not explicitly presented. This

    also applies to Romano and Vinelli (2001), who try to

    distinguish SCM from logistics, but fail to discuss the

    theoretical ground for this type of inter-organizational

    management. The importance of interactions between

    different parties is presented and discussed by Salvador et al.

    (2001). However, these interactions were rather accepted as a

    given status than critically scrutinized.We presume the necessity of presenting and discussing

    organizational theories for managing supply chains and will

    therefore combine in this article four different theories:1 the principal-agent theory;2 transaction cost analysis;3 the network theory; and4 the resource-based view.

    We will show that our choice is based on the assumption that

    there might be no “right” theory for the management of

    supply chains.

    1.2 The research problem and objective of the paper

    This paper looks into how theories from other disciplines canbe applied within SCM and ultimately used to develop SCM.

    We follow Maaloee’s (1997) classification of theories, later

    discussed in the context of logistics by Arlbjoern and

    Halldorsson (2002), that explain a problem:. grand theories (particular science with specific concepts,

    e.g. philosophy of science);. middle-range theories (worked connections between a set

    of concepts represented by socio-economic theories

    applied in various managerial disciplines); and. small-scale theories (limited number of concepts

    presented as propositions, e.g. the “fit” model of

    products and supply chain by Fisher, 1997).

    In this paper, we will focus especially on Maaloee’s (1997)

    suggestion that middle-range theories can be used to reflect

    connections between a set of concepts that represent key

    decisions of SCM. Only few contributions demonstrate how

    to deal with the phenomena of SCM from a middle-range

    theoretical perspective (New, 1997; Mears-Young and

    Jackson, 1997; Olavarrieta and Ellinger, 1997; Handfield

    and Melnyk, 1998; Logan, 2000; Arlbjoern and Halldorsson,

    2002; Ketchen and Guinepero, 2004; Cousins, 2005).The objective of our article is to develop and discuss a

    middle-range theoretical foundation of SCM based on

    different notions of socio-economic theories trying to

    explain inter-organizational phenomena. We use these

    theories because we are interested in answering two questions:1 How to structure a supply chain when it is perceived as a

    collaboration of institutions?2 What is needed to manage a particular structure?

    To gain insights into the institutional set-up of SCM

    arrangements, we have established a frame of reference that

    allows us to look at SCM from an institutional and socio-

    economic perspective. We have chosen transaction cost

    analysis (TCA) and the principal-agent theory (PAT) to

    answer the first question, as these theories are typically used

    to identify the best structure of and within institutions (e.g.

    Croom, 2001; Eisenhardt, 1989; Williamson, 1985, 1999;

    Coase, 1937). The second question will be answered by

    adapting the RBV and the network perspective (NT), because

    these theories look at institutions’ use of resources to stay

    competitive and the dynamics of inter-organizational

    relationships. All the selected approaches are well

    recognized in non-logistics disciplines, such as organization

    economics (TCA, PAT), marketing and purchasing, and

    strategic management (RBV), but so far their explanatory

    force has been sparingly applied in SCM (see Croom, 2001;

    Logan, 2000; Skjoett-Larsen, 1999). All four theories, each of

    which touches upon specific issues related to SCM, have amuch longer history in business management than theconcept of SCM itself.On this basis, we will show how the developed frame of

    reference can be applied to two SCM research domains:1 third party logistics (TPL); and2 new product development (NPD).

    These two areas have been chosen for several reasons. First,

    both are of strategic importance for managing the supplychain. Second, both are important elements in the SCMconcept. Third, both areas imply the creation of a long-term,inter-organizational arrangement that not only aims to

    promote operative improvements, but also to guide or leadthe strategic direction of companies. Fourth, they representtwo distinctive functional streams in a supply chain that aregaining increasing importance, both within academia and

    companies:1 service; and2 research and development (R&D).

    Although the strategic impact of NPD has always been a part

    of SCM, only recently has it received more attention in theliterature, especially under the topics of early supplierinvolvement in NPD (see Dowslatshahi, 1998; Wynstraet al., 2001; Ragatz et al., 1997; Wasti and Liker, 1997), masscustomization (see Duray et al., 2000; Salvador et al., 2002;Pine, 1993; Mikkola and Skjøtt-Larsen, 2004), andpostponement (see van Hoek, 2001; Pagh and Cooper,1998; Feitzinger and Lee, 1997; Ernst and Kamrad, 2000).

    This is not surprising, as many high-tech industries are facingincreasing challenges imposed by shorter product life cycles,increasing customization of products, and supply chainintegration. Not only are these firms contemplating

    outsourcing their NPD activities, they also have to maintainsustainable growth and stay profitable. Many firms, such asVolkswagen, Lego, Sony and Philips, are coping with thesechallenges through platform strategies to meet their

    customers’ needs while protecting their core competencies.When product innovation is perceived as the source ofcompetitive advantage, product architecture design strategiesthrough modularization and related outsourcing decisions

    become a central issue in SCM. Component and NPDoutsourcing decisions are typically made concurrently withthe decomposition of product architectures, from whichrecombinability, substitutability, commonality, and

    distinctiveness possibilities are determined (Mikkola,2003b). The success of NPD activities depends on theamount of transaction costs incurred, resource allocation,power propensity among the members of the supply chain,

    and inter-organizational dependencies shared between allmembers in the supply chain.TPL is also progressively representing multiple facets that

    share some important features of SCM relationships. Moreimportantly, its managerial practice consists of logisticsoperations performed by a TPL provider on behalf of theircustomers. According to Berglund et al. (1999), TPLrepresents a “separate industry” creating value for theircustomers, not only in terms of costs but also in terms ofdeveloping the customer’s business processes. Thesecompanies are often themselves organized in a network of

    operators with various skills representing multiple locations(Hertz and Alfredsson, 2003). TPL, or outsourcing of

    resources and competencies, may take years to conduct

    (Andersson and Norrman, 2002). Beyond the acquisition ofservices and development of the particular solution is the

    management of relationships between buyers and logistics

    providers, which often takes the form of a close, long-termrelationship in which trust may serve as a coordination

    mechanism in addition to the formal contract (Skjoett-Larsen, 2000). Empirical evidence demonstrates that TPL

    arrangements have become an important feature of the

    buyer’s attempt to exploit, leverage, and develop logisticsresources and competencies through inter-firm relationships

    (see, for example, Halldorsson and Skjoett-Larsen, 2004).The article is structured as follows. After an introduction,

    which includes an argument for the need of this research, we

    present our understanding of SCM and theory building. Inthe third section, we introduce the four theories that are

    developed outside SCM thinking and practice, but which

    nevertheless can be useful in structuring and analyzingmanagement decisions in supply chains. The paper concludes

    with a summary of our efforts and a critical outlook on future

    research.

    2. The theoretical foundations of SCM

    The supply chain encompasses organizations and flows ofgoods and information between organizations from raw

    materials to end-users (Handfield and Nichols, 2002). The

    supply chain is a meta-organization built up by independentorganizations that have established inter-organizational

    relationships and integrated business processes across theborderlines of the individual firms. A supply chain can also be

    characterized as a borderless organization (e.g. Picot et al.,2001), a value net (Bovet and Martha, 2000), a virtual supplychain (Chandrashekar and Schary, 1999), an interactive firm

    (Johansen and Riis, 2005), a multi-organization/single-site

    coordinated operations network (Rudberg and Olhager,2003), or an extended enterprise (Davis and Spekman,

    2004; Boardman and Clegg, 2001). Management of such anarrangement refers to inter-organizational relationship

    management with the objective of improving the overall

    profitability of the activities and/or organizations involved.The current literature on SCM seems to agree on the nature

    of the phenomena (e.g. Persson, 1997).Although SCM has existed for almost 25 years, it still lacks

    a socio-economic theoretical basis that may be used to explain

    and understand this particular form of inter-organizationalarrangement. Initially, two consultants from Booz, Allen and

    Hamilton (Oliver and Webber, 1982) introduced the SCM

    concept. Several authors have traced the theoreticalfoundations of SCM. Thus, Svensson (2002) found that the

    theoretical foundation of SCM and Alderson’s functionalist

    theory (Alderson, 1957) have many similarities. Mentzer et al.(2004) presented a unified theory of logistics based upon

    logistics capabilities as a source of competitive advantage.Recently, academics have presented valuable contributions,

    enhancing our understanding of the concept of inter-

    organizational management of different flows of productsand/or information (e.g. Ballou et al., 2000; Heikkilä, 2002;Monczka and Morgan, 1997; Srivastava et al., 1999; Frazier,

    1999; New and Westbrook, 2004). The majority of

    contributions focus on definitions and concepts from afunctional point of view (e.g. logistics, operations, marketing,and purchasing), providing pragmatic recommendations onhow to improve a firm’s performance and implementation ofpostponement by supply chain reconfiguration. Prominentexamples of such approaches can be found in Mentzer et al.(2001), Cooper et al. (1997), Cigolini et al. (2004), Lambertet al. (2005) and Croxton et al. (2001). Current frameworksof SCM present solutions on how to design and manageparticular relationships between various stages in a chain, butthey do not address the economic, strategic, and socio-economic theoretical rationales behind them (e.g. Min andMentzer, 2004; Chen and Paulraj, 2004a, b).The next section discusses SCM from the four chosen

    inter-organizational theories, and makes a cross-comparisonbased on specific characteristics of the theories.

    3. Developing a middle-range theoretical base forSCM

    3.1 Fundamental issues of SCM

    The literature supports the view that the integration of keybusiness processes within and across companies that addvalue for customers and other stakeholders can be called

    SCM (see Cooper et al., 1997; Bechtel and Jayaram, 1997).Definitions of SCM originate from the operationsmanagement literature referring to issues such as NPD,customization and distribution of goods, including thebalancing of demand needs and capacity requirements inthe transformation of raw materials into final productsdelivered to customers (e.g. Lee, 1993). Within the logisticsdiscipline, Cooper and Ellram (1990, p. 2) define SCM as an“integrative philosophy to manage the total flow of adistribution channel from supplier to the ultimate user”.Both Harland (1996) and Christopher (1998) reach anotherconclusion. Instead of managing flows, SCM is seen as themanagement of a network. Harland (1996, p. 64) defines

    SCM as “the management of a network of interconnectedbusinesses involved in the ultimate provision of product andservice packages required by end customers”. Rather thanlooking at SCM as the management of a vertical pipeline ofinter-linked firms, Harland (1996) considers SCM asmanagement of a complex network of organizations involvedin exchange processes. Christopher (1998) argues that theword “chain” should be replaced by “network”, since the totalsystem normally includes multiple suppliers and customers aswell as multiple suppliers to suppliers and customers’customers. Some scholars (e.g. Christopher, 1998; Heikkilä,2002) also suggest that “supply chain management” shouldreally be termed “demand chain management” to reflect thefact that the chain is driven by the marketplace to satisfy the

    needs of the end-users. Another argument is that withinmarketing SCM is presented as one of the core businessprocesses, which includes purchasing and physicaldistribution activities (e.g. Srivastava et al., 1999).However, all attempts refer to one specific “setting”, which

    is the management of relations of independent organizationsin a particular structure. Consequently, we understand such

    management as the coordination and interaction of decisionmakers (i.e. human beings) from economic institutions withina system based on division of labor (Göbel, 2002). In thatsense, we develop a middle-range theoretical frame of

    Complementary theories to supply chain management

    Arni Halldorsson et al.

    Volume 12 · Number 4 · 2007 · 284 – 296

    286

    reference to explain SCM based on TCA, the PAT, the RBVand the NT. We do not claim that these theories are the onlyones that can be used to establish a theoretical framework ofSCM. But since we understand supply chains asinterconnected socio-economic institutions, we argue thatthese theories are most useful to explain both structure andmanagement issues of supply chains. Other theories andframeworks that focus on other aspects of SCM includerelational contracting theory and resource dependency theoryfrom the organizational sciences (e.g. MacNeil, 1980; Pfefferand Salancik, 1978), the political economy frameworks (e.g.Stern and Reve, 1980), the dynamic capabilities framework(Teece et al., 1997; Eisenhardt and Martin, 2000), and theevolutionary theory of economic change (Nelson and Winter,1982). These supplementary aspects include power regimesin supply chain relations (Cox et al., 2001), dynamic design,redesign of the firm’s chain of capabilities (Fine, 2000), andthe importance of path dependence and organizationalroutines (Nelson and Winter, 1982). However, it is beyondthe scope of the current paper to discuss these supplementaryaspects.

    3.2 The logic of the selected set of inter-organizational

    theories3.2.1 SCM mitigating agency problems – the principal-agenttheory (PAT)Based on the separation of ownership and control ofeconomic activities between the agent and the principal,various agency problems may arise, such as asymmetricinformation between the principal and the agent, conflictingobjectives, differences in risk aversion, outcome uncertainty,behavior based on self-interest, and bounded rationality. Thecontract between the principal and the agent governs therelationship between the two parties, and the aim of thetheory is to design a contract that can mitigate potentialagency problems. The “most efficient contract” includes theright mix of behavioral and outcome-based incentives tomotivate the agent to act in the interests of the principal(Eisenhardt, 1989; Logan, 2000).The alignment of incentives is an important issue in SCM.

    Misalignment often stems from hidden actions or hiddeninformation. However, by creating contracts with supplychain partners that balance rewards and penalties,misalignment can be mitigated (Narayanan and Raman,2004; Baiman and Rajan, 2002).

    3.2.2 SCM as coordination of transferred rights of disposals –transaction cost analysis (TCA)TCA offers a normative economic approach to determine thefirm’s boundaries and can be used to present efficiency as amotive for entering inter-organizational arrangements(Williamson, 1975, 1985, 1996). A company may reduce itstotal transaction costs (ex ante and ex post costs of contact,contract, and control) by cooperating with external partners.The key question is: why do firms exist? In the context ofSCM, this question is addressed as: which activities should beperformed within the boundary of each firm, and whichactivities should be outsourced? SCM relationships arerepresented by the hybrid mode of governance betweenmarkets and hierarchies. Asset specificity (limited value in analternative application of, for example, physical, site, human,and dedicated assets) is the most influential attribute of thetransaction (Rindfleisch and Heide, 1997). Behavioralassumptions of bounded rationality and the risk of being

    subject to opportunistic behavior from a partner also

    influence the transaction costs. Bounded rationality may

    result from insufficient information, limits in management

    perception or limited capacity for information processing.

    Mechanisms for mitigating the risk of opportunism include

    safeguards and credible commitments such as long-term

    contracts, penalty clauses if a partner fails to fulfill the

    contract, equity sharing, and joint investments. According to

    Williamson (1996), trust between the parties is based on

    “calculated risk” and not on personal trust between

    individuals.TCA has often been used in make-or-buy decisions in

    supply chains. Examples are outsourcing of logistics activities

    (Maltz, 1993; Andersson, 1997; Halldorsson, 2002), buyer-

    supplier relationships (Mikkola, 2003b; Bensaou, 1999;

    Stuart and McCutcheon, 1996), and restructuring of supply

    chains (Croom, 2001). In essence, TCA is a useful

    instrument to decide whether a transaction should be

    performed in the marketplace or in-house.

    3.2.3 SCM as reciprocated interactions between institutions –the network perspective (NT)The performance of a firm depends not only on how

    efficiently it cooperates with its direct partners, but also on

    how well these partners cooperate with their own business

    partners. NT can be used to provide a basis for the

    conceptual analysis of reciprocity (Oliver, 1990) in

    cooperative relationships. Here, the firm’s continuous

    interaction with other players becomes an important factor

    in the development of new resources (Haakansson and Ford,

    2002). Relationships combine the resources of two

    organizations to achieve more advantages than through

    individual efforts. Such a combination can be viewed as a

    quasi-organization (Haakansson and Snehota, 1995;

    Haakansson, 1987). The value of a resource is based on its

    combination with other resources, which is why inter-

    organizational ties may become more important than

    possessing resources per se. Thus, the resource structuredetermines the structure of the supply chain and becomes its

    motivating force. The network theory (NT) contributes

    profoundly to an understanding of the dynamics of inter-

    organizational relations by emphasizing the importance of

    “personal chemistry” between the parties, the build-up of

    trust through positive long-term cooperative relations and the

    mutual adaptation of routines and systems through exchange

    processes. Through direct communication, the relationships

    convey a sense of uniqueness, ultimately resulting in supply

    chains as customization to meet individual customer

    requirements. The parties gradually build up mutual trust

    through the social exchange processes. A network does not

    seek an optimal equilibrium, but is in a constant state of

    movement and change. Links between firms in a network

    develop through two separate, but closely linked, types of

    interaction: exchange processes (information, goods and

    services, and social processes) and adaptation processes

    (personal, technical, legal, logistics, and administrative

    elements) (Johanson and Mattsson, 1987).NT is descriptive in nature and has primarily been applied

    in SCM to map activities, actors, and resources in a supply

    chain. The focus has been on developing long-term, trust-

    based relationships between the supply chain members.

    Examples of issues include buyer-supplier relationships

    287

    (Halldorsson, 2002), and management roles in supply

    networks (Harland and Knight, 2001).

    3.2.4 SCM as coordination of relational assets – the resource-based view (RBV)Only a few articles have applied the resource-based view

    (RBV) to the field in focus in order to obtain the sources ofcompetitive advantage through SCM (Lewis, 2000; Pandza

    et al., 2003; Rungtusanatham et al., 2003; Carr and Pearson,2002) or to analyze the structure of chains and industrial

    clusters (Miller and Ross, 2003; de Olivera Wilk andFensterseifer, 2003).The RBV deals with competitive advantages related to the

    firm’s possession of heterogeneous resources (financial,

    physical, human, technological, organizational, andreputational) and capabilities (combination of two or more

    resources) (Grant, 1991; Penrose, 1959; Prahalad andHamel, 1990). These resources and capabilities constitute

    the core competence of the particular firm and serveultimately as its source of competitive advantage. The static

    stream of research focuses on attributes that contribute to theheterogeneity of resources and capabilities. Four barriers may

    prevent competitors from imitating a firm’s resources andcapabilities:1 durability;2 transparency;3 transferability; and4 replicability (Prahalad and Hamel, 1990).

    These attributes may also apply to inter-organizationalarrangements (Jap, 2001). The more dynamic aspects of the

    RBV consider a firm’s core competence to be its ability toreact quickly to situational changes and build further

    competencies (Prahalad and Hamel, 1990) or dynamiccapabilities (Eisenhardt and Martin, 2000). Hence, a firm’s

    competitiveness is associated with the configuration ofresources and capabilities as the markets evolve. However,

    inter-organizational relationships may also facilitate andadvance the learning processes of individual firms. As such,

    relationships are not only output-oriented but also learning-oriented. Efficiency may not only be explained in terms of

    productivity or operational measures, but also in terms of theopportunity to access another firm’s core competencies

    through cooperative arrangements as an alternative tobuilding such competencies in-house (Haakansson et al.,1999).The RBV is an implicit assumption in many supply chain

    decisions. Often, outsourcing decisions are based on the ideaof focusing on core competencies and outsourcing

    complementary competencies to external partners. TPL andoutsourcing of standard components and processes to

    subcontractors are examples. However, outsourcing ofdesign, NPD, or software development is often a way to

    gain access to other supply members’ core competenciesthrough inter-organizational collaboration.Table I summarizes and compares the specific

    characteristics of the four selected theories, which should

    be viewed as complementary and not mutually exclusive.The PAT stresses issues of inter-firm contracting and

    ultimately the notion of supply chain transparency. TheTCA considers hybrids such as integrated supply chains as

    the result of a market failure, whereas the NT and the RBVsee the supply chains as a means to access resources and

    competencies outside the focal firm (Skjoett-Larsen,

    1999). Easton and Araujo (1993) assert that the RBV

    poses a “narrow conceptualization of the firm as a businessentity” indicating that this stream of research may benefit

    from both the network approach (NT) and the vision ofSCM.In the following sections, we demonstrate how the four

    theories can contribute to answering our two questions

    adapted to two selected fields of application within SCM:1 third party logistics (TPL); and2 new product development (NPD).

    4. The theoretical framework applied tothird-party logistics (TPL)

    Within the realm of SCM, the case of TPL illustrates the

    efficient governance structure for the “make-or-buy” decisiondepending on the characteristics of the transactions. Table II

    provides an overview of how the four theories can be appliedto TPL. The four theoretical approaches increase our

    understanding of TPL by offering a complementary view ofwhy TPL relationships exist (TCA), just as they guide inter-firm interactions based on contracts (PAT) into long-term

    relationships (NT) supporting a firm’s core competence(RBV).

    4.1 The principal-agent theory and TPL

    Balancing the need of the shipper and the capability of the

    TPL provider is a well-known managerial issue (e.g. Hertzand Alfredsson, 2003) that explicitly implies the risk ofagency problems. The PAT suggests an “inter-firm

    contracting perspective” on TPL, focusing on the designof an efficient contract between the buyer and seller of

    logistics services. The idea is to develop the most efficientcombination of outcome and behavioral incentives in the

    contract between the shipper and the TPL provider. Theextent to which the TPL provider’s performance can bemeasured and controlled has a great effect on whether the

    provider is paid by actual performance (e.g. number oforders picked, packed, and shipped to the customers) or

    according to behavioral outcomes (e.g. salaries, hours, and/or miles). Not all aspects can be covered ex ante in thecontract. Therefore, the issue of contracting should be arevisiting issue in TPL relationships.

    4.2 Transaction cost analysis and TPL

    By reducing the supplier base of transport firms and enteringinto close and long-term cooperation with a few key

    operators, a firm may reduce the transaction costs related tocollecting information about numerous suppliers, the costs of

    negotiating and writing a contract, and the enforcement costsafter the negotiation of a contract. However, closecooperation also involves the risk of opportunistic behavior.

    Therefore, it might be necessary to incorporate “safeguards”and “credible commitments” into TPL agreements, such as

    penalty clauses related to poor delivery performance, jointinvestments in dedicated warehouses or equipment, joint

    training programs, and exchange of employees between thefirms.

    4.3 The network perspective and TPL

    To TPL, the NT presents openness and trust between theparties as a condition for gaining the best possible results

    from cooperation. Over time, mutual adjustments improve

    Complementary theories to supply chain management

    Arni Halldorsson et al.

    Supply Chain Management: An International Journal

    Volume 12 · Number 4 · 2007 · 284 – 296

    288

    administrative and logistical systems, making them more

    efficient. Examples of adjustment processes might be an

    electronic data interchange (EDI) connection between the

    client and the TPL operator or the implementation of a

    quality control system. By entering into close cooperation

    with TPL providers who possess complementary

    competencies, the individual firm is able to utilize

    resources and skills controlled by other players. In close

    and long-term cooperation, the parties are able to establish

    mutual and strong relations of trust, which may result in the

    disappearance of cost-consuming, contractual safeguards.

    Thus, firms with efficient, cooperative arrangements might

    gain competitive advantage over firms that have to bear

    transaction costs to prevent their transport firms from acting

    in an opportunistic way.

    4.4 The resource-based view and TPL

    Similar to TCA, the RBV applies a stringent perception to the

    firm’s boundaries. Resources and capabilities can only be

    acquired from the market to a limited degree. Under certain

    circumstances, firms in the supply chain interact closely on a

    long-term basis exchanging confidential information. Hence,

    TPL is both a means of improving the logistics services of the

    TPL buyer and a way to achieve a mutual transfer of logistics

    experience. A long-term mutual commitment and

    adjustments as well as a customized rather than

    standardized solution contribute to the uniqueness and

    heterogeneity of logistics resources and capabilities. Besides

    the static dimensions of heterogeneity (inimitable attributes of

    resources and capabilities), RBV can help us to understand as

    to how to use TPL to shortcut an upcoming need for

    competence configuration (building and development)

    (Halldorsson and Skjoett-Larsen, 2004). The focal point of

    discussion is the ability of TPL to create venues throughlearning, either jointly or from each another, which may

    support the building of a core competence. This approach is

    similar to the view of TPL as a means to configure logisticscompetencies (Halldorsson, 2002).

    5. The theoretical framework applied to newproduct development (NPD)

    Within the realm of SCM, we focus our discussion on

    modularization of product architecture design strategies (seeMikkola, 2003a, b; Momme et al., 2000) and how supplier-buyer relationships impact such NPD decisions (see Wasti

    and Liker, 1997; Dyer et al., 1998; Hsuan, 1999). The fourtheoretical approaches provide us with additional insights

    connecting NPD to SCM, as shown in Table III.

    5.1 The principal-agent theory and NPD

    Firms’ NPD activities are often proprietary in nature, whichmakes firms reluctant to involve suppliers in their activities.

    Product architecture designs suggest which NPD tasks might

    be performed by suppliers and how. Hence, specific assetsshared with the suppliers have to be determined. Specialized

    assets (in contrast to general assets) often have a narrow range

    of potential applications and are difficult to deploy (Christyand Grout, 1994). Co-specialized investments, on the other

    hand, increase the principal and agent’s interdependence and

    serve as an economic rationale for cooperative, long-termrelationships. Furthermore, shared standards reduce

    specificity and provide a form of embedded control

    (Sanchez and Mahoney, 1996), reducing search,

    monitoring, and enforcement costs, which allows firms to

    make efficient exchanges with multiple partners. Such a cost

    reduction will subsequently lessen a firm’s incentive to

    integrate activities internally and free it to pursue the

    advantage of flexibility when there are high levels of input

    and demand heterogeneity (Mikkola, 2003c).

    5.2 Transaction cost analysis and NPD

    In a TCA perspective, it is argued that modularization

    reduces transaction costs. Modular systems lower the

    transaction costs of information about the parts available

    (for a firm) and imply economies of scale in assembling the

    package (for a consumer) (Langlois and Robertson, 1992).

    Product architectures made up entirely of standard

    component would favor market governance. One incentive

    to devise modular product architectures is to have

    components with standardized interfaces to enable

    competition between suppliers on technology innovation. To

    reduce transaction costs, firms may outsource product

    development and manufacturing activities of certain

    components to qualified suppliers. Firms naturally try to

    find the optimal trade-offs between switching costs and

    performance between partners, which will depend on the

    length of relationships shared between the buyer and its

    suppliers.

    5.3 The network perspective and NPD

    In many industries, such as the PC and bicycle industries,

    there is a large variety of interchangeable components readily

    available. Interchangeability of components in modular

    systems encourages vertical specialization, leading to the

    creation of networks. One force speaking for verticalspecialization is the dissimilarity among production stages.When resources are recombined in new ways, a number ofinterfaces with other resources need to be considered.Components and systems have to be designed so they areeasy to assemble and transport. Handling this complexity hasbecome increasingly important due to the ongoing changes ofactivity structures in industries. Furthermore, an increasingreliance on outsourcing leads to substantial interdependenciesbetween the activities of different firms. One way to solve thiscomplexity is through modularization and product platformdesigns (Mikkola, 2003c).

    5.4 The resource-based view and NPD

    Modularity management of product architectures can beviewed as the management of a firm’s resources. It takes timeand money to develop the capabilities associated with productarchitecture designs, and the subsequent market success (orfailure) of the firm is dependent on the architecture’sconfiguration (i.e. heterogeneity of resources and causalambiguity), the extent of certain technologies andcomponents’ (i.e. resources and assets) inimitability bycompetitors, and the management of resources that must beshared with suppliers, especially when complementary assetsare involved (Teece, 1986).

    6. Frame of reference for SCM

    Since supply chain thinking emerged, researchers fromdifferent disciplines have been in search of a theoreticalfoundation for the phenomenon. Chen and Paulraj (2004a,b), Croom et al. (2000), Svensson (2002), Mentzer et al.(2004), and Ganeshan et al. (1998) have pointed to differentbodies of literature and management problems relating tosupply chain management (SCM). Recently, Cigolini et al.(2004) presented SCM as resulting from a specific set ofmanagement and supporting tools that may be formed toachieve successful management of different supply chains. Butnone of these authors have presented a theoretical analysis ofthe phenomenon SCM.As we interpret SCM as a network of socio-economic

    institutions, we have chosen a set of relevant theories that canbe applied to the management and structuring of specificSCM arrangements (see Figure 1). The upper part of thefigure includes the four different theories that we havecombined to answer our two research questions:1 How to structure a supply chain of collaborating

    organizations?2 How to manage a particular structure?

    The lower part of the figure illustrates the managerial arena ofSCM, including the key elements (Lambert et al., 1998), theprerequisites, and the outcome.One of the contributions of the paper is the attempt to

    mitigate the gap between the current SCM research andpractice and the theoretical explanations of how to structureand manage supply chains. The lower part of Figure 1illustrates the characteristics often related to SCM. The leftpart lists a number of preconditions, which can be found inmost theoretical and empirical studies of inter-organizationalrelationships, such as trust, long-term collaboration, mutualcommitments, and willingness to share costs and benefits.The middle section shows the interactions between structure,processes, and management, which constitute the core of the

    SCM concept. The right side shows the expected effect on

    SCM performance measured in terms of higher cost efficiency

    internally or in the interfaces between the SCM participants,better customer service, and higher flexibility and

    responsiveness towards changes in the customers’ needs andexpectations. The upper part of Figure 1 shows the “missing

    link” – a theoretical framework to analyze and explain thephenomena in the management arena of SCM.

    7. Managerial implications

    In this paper, we have proposed four different theories to beapplied when making decisions on the structure and the

    management of supply chains:1 transaction cost analysis (TCA);2 the principal-agent theory (PAT);3 the network theory (NT); and4 the resource-based view (RBV).

    Both TCA and the PAT have their roots in neo-classical

    economic theory and are especially valuable when it comes tothe issue of how to structure the supply chains. Important

    management decisions include, for example:1 Which activities should the firm keep in-house, and which

    activities should preferably be outsourced to externalpartners in the supply chain?

    2 What should be the roles, positions, and responsibilities of

    the participants in the supply chain?3 How can the firm safeguard against the risk of

    opportunism from the other participants in the supplychain?

    4 How should the incentives be aligned internally andbetween the participants in order to further the outcomes

    of the supply chain?

    However, TCA and the PAT have limitations due to the

    embedded assumptions about human behavior and the staticview of the firm’s boundaries. Therefore, it is necessary to

    apply complementary theories, which can explain the

    dynamics in governance structures and inter-organizationalrelationships. Here, we have examined such challenges with

    the following two complementary theories: the NT and theRBV. The NT is basically a descriptive theory that examines

    how interacting companies in a supply network adapt theirprocesses and systems to each other by exchange processes,

    and how they can develop trust and confidence in inter-organizational relationships over time. Trust is an important

    precondition in SCM. This is especially true in NPD, which

    often involves early supplier involvement in order to speed uptime-to-market or to gain access to the latest technology.

    Trust can also serve as a governance mechanism in hybridorganizations, in line with price in the market and authority in

    the hierarchy (Bradach and Eccles, 1989).The RBV complements TCA by considering the resources,

    capabilities, and competencies both inside the individual firmand in the linkages between the firms in a supply chain. The

    resources and capabilities of the firms play an important role

    in boundary decisions, as discussed by Barney (1999). WhereTCA explains the boundary of the firm by characteristics

    related to the transactions (e.g. asset specificity anduncertainty), the RBV looks at the capabilities of the firm

    and the capabilities of potential partners in the supply chainswhen deciding which activities should be outsourced and

    which should be kept in-house. Combs and Ketchen (1999),

    Complementary theories to supply chain management

    Volume 12 · Number 4 · 2007 · 284 – 296

    291

    however, warns that firms should be careful with the selectionof theory used to explain inter-firm cooperation, as theysometimes come up with contradictory explanations. Theirempirical findings showed that firms do not simply respond tothe logic of only RBV or TCA, but rather react tocontingencies identified by both. Barney (1999), forexample, argues that the normative implications of TCAand RBV, respectively may differ; despite the circumstances ofhigh asset specificity and risk of opportunistic behavior, inwhich TCA would recommend a “in-house” solution, whileRBV would prescribe circumstances where outsourcing wouldbe necessary. Cousins (2005) discusses this theoreticalintersection further and suggests that supply andrelationships modes must align with strategies of the firm.

    8. Research implications

    The research implication of this eclectic approach to SCM isthat we cannot rely on one theoretical explanation (e.g. TCAor the RBV) when analyzing phenomena in SCM. We have toconsider several theories and how they may complement eachother in order to provide a more comprehensive view of SCM.Depending on the concrete situation, we can choose onetheory as the dominant explanatory theory, and thencomplement with one or several of the other theoreticalperspectives. The four theories selected in this paper aresupported by empirical evidence provided mainly by theliterature, both in general and also to some extent within therealm of SCM. The way the four theories complement eachother is explored on a conceptual basis, but further researchinto this direction may explore more deeply how these allegedcomplementarities occur in practice, and how managers

    mould their decisions by these ideas. In so doing, the

    theoretical development of SCM may reach beyond a mere

    battle of intellectual territories urging managers to operate in

    a wider, or almost infinite, domain. The main message in this

    paper is therefore that there is no such thing as “a unified

    theory of SCM”.

    9. Conclusions

    The starting-point of our considerations focused on two the

    attempt of explaining two research questions:1 How to structure a supply chain?2 How to manage a particular structure?

    These questions are important, as many decision makers in

    business practice as well as in academia address these issues

    more often than to think of new possible definitions on the

    phenomena of inter-organizational management of

    transformation flows between production and consumption.We have presented an argument that builds on organization

    theories in order to answer our questions, and this can be seen

    as an attempt to diminish the gap between current SCM

    research and practice and existing theoretical descriptive and

    prescriptive explanations.We have therefore developed a general framework where we

    combine the managerial SCM arena with four different

    organization theories in order to explain our two research

    questions, and we use our framework for looking at two

    different problem areas within SCM:1 third-party logistics; and2 new product development.

    We find that we cannot rely on one unified theory to explain

    inter-firm governance structure and management decisions in

    a supply chain, but have to apply complementary theories.Furthermore, we can show that building a unified theory of

    SCM might be difficult, as many problems can occur whose

    solution might depend on different theoretical backgrounds.

    In that sense we have shown how our theoretical choice has

    shown different results depending on the observation

    perspective.We suggest that further empirical and theoretical research is

    needed in order to find out the contingencies for choosing a

    specific combination of theories that adequate explains

    management decisions related to configuring and managing

    supply chains.

    Keywords:Supply chain managementSustainabilityConceptual developmentSupplier managementRisk and performance management

    Sustainable supply chain management (SSCM) emerged as a niche topic around 20 years ago but moved intothe mainstream. This paper revisits some of the conceptual developments of the field‐building on Seuring andMüller (2008). We draw upon this framework and its core constructs to revisit the status quo of theory devel-opment in SSCM. We reflect on the research needs for each construct of the initial framework. Some constructs,like drivers and barriers, are well researched, while stakeholder management issues or supplier developmentwarrant future research. Risk and performance aspects will stay on the agenda, albeit some more criticalaccounts are needed. This discussion forms the second main part of the paper thereby pointing toward futureresearch needs. The link between digital transformation and sustainable development would be one of the coretopics driving change in SSCM. More research on emerging economies and the environmental and socialimpact of supply chains in such contexts would be welcome. Contemplating on the constructs’ content andarrangement for prospective future endeavours drive this research, while not conducting a complete analysisincluding all aspects can be seen as a limitation.

    1. Introduction

    In line with the increasing relevance of sustainable development,research on sustainable supply chain management (SSCM) has nowreached the mainstream. While several of the SSCM issues raised byPagell and Shevchenko (2014) remain and true sustainability is stillan aspiration of most supply chains, there is progress on multiplefronts of related research. The existing multitude of papers raises ques-tions of how to position future research and drive the field forward.This would also respond to, e.g., the critique rightly put forward byCarter and Washispack (2018) that there might be no need anymorefor structured literature review papers providing a broad overviewof the topic. Yet, following (Seuring et al., 2021), it is a “normal” ques-tion of how to identify a research gap and to position research accord-ingly, irrespective of the method employed for the single piece ofresearch.

    Based on a critical reflection of the SSCM domain, we address thefollowing research questions: What are the conceptual elements ofSSCM? How has theory development in SSCM evolved? How canfuture research directions be identified?

    Following the well‐cited conceptual work by Seuring and Müller(2008), this paper is based on the first author’s knowledge and experi-ence in the field of (S)SCM since the early 2000s. We adopt Seuringand Müller’s (2008) structure as a blueprint for the arguments raisedhere and, consequently, follow the triggers, supplier managementand sustainable products logic. Based on Weick’s (1989) insights into“theory construction as disciplined imagination,” our reflections con-tribute to designing, conducting and interpreting imaginary experi-ments through which carefully selected papers provided us withfurther evidence to explain SSCM developments.

    A note of caution is due here. First, we ground our reflections onvarious papers, yet we do not systematically review the SSCM litera-ture. Second, the adopted conceptual elements might not captureevery facet of the SSCM literature. In line with Seuring and Müller(2008), we did not consider transport and logistics or reverse logisticsaspects. However, the adopted conceptual elements are meaningful, asthey fulfil the often‐asked criteria of being mutually exclusive but col-lectively exhaustive (often acronymised as MECE). Each conceptualelement has its own core and sums up arguments on specific content.Overall, the original framework outlines many debates in SSCM, and

    y.sel.de (F.

    S. Seuring et al. Cleaner Logistics and Supply Chain 3 (2022) 100016

    the lines of reasoning are still applicable. Third, there are issues wherecategories have links to each other. We clarify them subsequently,albeit and again, in a more selective and not in a systematic manner.Fourth, we use some papers in more than one category. In this respect,we depart from the logic of a structured literature review Seuring et al.(2021) to illustrate certain aspects of the debate. Nonetheless, wepoint out that the paper selection process can be subjective or missother pertinent papers. Finally, some bias derives from the fact thatthe paper’s first author refers to his own past research. Thus, the papercontains elements of personal reflections on the field.

    This leads us to structure the paper as follows. In the next section,we revisit Seuring and Müller’s (2008) paper and succinctly present itscore constructs. We then link each construct to research on relatedtopics in SSCM. This poses the challenge that some papers are posi-tioned at the intersection of topics; consequently, they might havebeen taken up in different parts. Next, we adopt the logic of the theory,method, and empirical field to unveil future research directions. Asthis paper is solely committed to discussing the developments of thefield, there is no discussion but a conclusion section.

    2. Identifying the conceptual core

    Seuring and Müller (2008) structure their paper into three parts,which can be used for empirical analysis (Seuring et al., 2019). Hence,the initial conceptual framework will briefly be summarised, and someconstructs will be identified, which will structure the subsequent sec-tion. This is one particular way of operationalising the framework,which might be challenged, as the focus is on single topics. Thisapproach might risk that overarching lines of research would not beaddressed, an issue we will return to at the end of this section. The sin-gle conceptual elements identified will be numbered against the logicof the subsequent text, which is also presented in Fig. 1. This allows amore logical form of arguments.

    1. Triggers for SSCM

    The central starting point for why companies deal with SSCM isseen in stakeholder groups exerting pressure on focal companies andproviding incentives outside of the company‐based factors. The twocore lines of theoretical developments are therefore on (1) stakeholdermanagement and (2) pressures and incentives, which also captureinternal drivers and barriers.

    2. Supplier management for risk and performance

    This part of the framework looks at the relationship of a focal com-pany and its (3) (multiple‐) tiers suppliers and related managementpractices. The core line of reasoning is based on supply managementand related processes, with a focus on (4) supplier selection and eval-uation. The results are categorised into (7) risk management and (8)

    Fig. 1. Core conceptual elements of Sustainable Supply Chain Management.

    2

    performance management of the supply chain, thereby focusing onthe outcomes to be achieved.

    3. Supply chain management for “sustainable” products

    The third building block, where Seuring and Müller (2008) providea figure for summing up elements, centres on the product dimension.The next conceptual element relates to supplier management processes,particularly in (3) multi‐tier supply chains, where (5) supplier develop-ment and (6) communication and collaboration take a central role. Thisoften requires or aims at moving toward (9) sustainable products.

    In sum, a visual representation of the nine conceptual elements iden-tified above is presented in Fig. 1. Admittedly, Fig. 1 solely shows themost common connections between focal companies and related SSCMconceptual elements. As the subsequent sections will show that there aremultiple ways of reasoning, the aim here is to sum up the key SSCM con-ceptual elements. The first two conceptual elements link the focal com-pany to stakeholders. Numbers (3) to (6) look at the supplier side and thefocal company’s relationships with suppliers. On the outcome side, andtherefore connected by uni‐directional arrows, there is on the one handside the link to (7) risk and (8) performance management, while there isalso the link to offering (9) sustainable products and services.

    3. Reflecting on the conceptual elements

    1. Stakeholder managementInitially, Seuring and Müller (2008) explore how SSCM is coming

    into force or why companies turn to it. The central starting point isthe stakeholder perspective, which has received much attention andis mentioned in multiple papers. In this regard, one key aspect ishow stakeholder management takes place and how it might be shapedor how it might shape SSCM. Systemising the pressure of multiplestakeholder groups that might get involved into supply chains,Meixell and Luoma (2015) point to a three‐step process of awareness,adoption and implementation of sustainability in the supply chain.This aligns with stakeholder theory and its application in sustainabilityand points to sustainability‐based value creation for stakeholders(Hörisch et al., 2014). Interesting perspectives have been added,where Liu et al. (2018) distinguish three roles for stakeholders: driver,facilitator and inspector. This moves beyond the pressure debate andoffers insights that stakeholders do much more than just pressuringcompanies. The facilitator role has been explored by, e.g., Rodríguezet al. (2016), who show how nongovernmental organisations (NGOs)can take an active role in developing and managing supply chains.The authors offer insights into how NGOs apply their knowledge, pro-vide bridging capabilities and enable organisational routines in thenetworks, thereby helping to establish sustainable supply chains(Cole and Aitken, 2020). This allows implementing sustainability ini-tiatives and reaching social and economic goals. The inspector roleis relevant for the debate on environmental and social standards(Seuring et al., 2019), while this then falls short of the more proactiveroles (Liu et al., 2018) and related stakeholder management practices(Siems and Seuring, 2021).

    A special but not much addressed issue is that stakeholder manage-ment can also be linked to corruption (Silvestre et al., 2018). Hence,this issue is a highly relevant research gap that requires additionalscholarly work. This would take a critical debate on the role of stake-holders, which can also raise false claims or even contribute to fraud ororganisational hostility (Markman et al., 2016). Still, in most cases, thepressures and incentives they offer are instrumental for driving changein corporate sustainability and supply chain management.

    Stakeholder theory still has to offer more for the SSCM field. Bothpositivist studies on engagement taking different forms as well as crit-ical studies on what might, but also what might not be achieved, arehighly welcome.

    S. Seuring et al. Cleaner Logistics and Supply Chain 3 (2022) 100016

    2. Pressures and incentives as well as drivers and barriers

    To understand what makes companies get involved in stakeholdermanagement Seuring and Müller (2008) distinguish among pressuresand incentives, rather driven by stakeholder pressure and external tothe focal company and its supply chains. Based on how certain barriersto greening supply chains might be overcome (Mathiyazhagan et al.,2013), the social aspects were also integrated (Bai et al., 2019). Thisfield has seen several papers consolidating drivers and barriers(Diabat and Govindan, 2011). Sajjad et al. (2015) distinguish internaland external motivators and barriers, somewhat following the logic ofSeuring and Müller (2008).

    More recently and linked to the stakeholder debate, scholarly dis-cussions on drivers and barriers have been extended to the circulareconomy (Govindan and Hasanagic, 2018). They also point to the rel-evance of governance aspects, a topic guiding a further stream ofSSCM research.

    As already mentioned in the previous section, further progressmight rather come from, e.g., the integration of different stakeholdergroups and their roles. Aspects of pressure would also be relevant link-ing to other theoretical domains, such as institutional theory (Sauerand Seuring, 2018) or institutional uncertainty (Kelling et al., 2020),where forms of pressure are taken up. This topic might only beexplored further when deliberate theoretical contributions would bemade, in some cases borrowing theory from other fields (Touboulicand Walker, 2015b).

    3. Multi‐tier supplier management

    Expanding the perspective from the direct suppliers, one highly rel-evant line of research is the one on multi‐tier supply chains(Tachizawa and Wong, 2014), which has been linked to sustainabilityissues (Govindan et al., 2021; Sauer and Seuring, 2018; Wilhelm et al.,2016a). In extreme cases, such as the frequently long mineral supplychain, upstream focal firms might play a central role overseeing thesupply chain closer to the virgin material. This is particularly challeng-ing as focal companies will frequently find it demanding movingbeyond the first‐tier, leading to a double agency role of the first‐tiersupplier, reporting to the focal company on the one hand side, butensuring compliance at lower tiers of the supply chain (Wilhelmet al., 2016b) and limiting supply chain visibility (Busse et al.,2017). Consequently, a cascaded approach is proposed, wheredemands, but also monitoring processes are passed on step by step(Sauer and Seuring, 2019), which should improve transparency forsustainability (Garcia‐Torres et al., 2019, 2021).

    Multi‐tier supply chain management and related sustainability issuesseem to warrant more research. The intersection particularly to the digi-tisation topic seems hardly explored so far. However, blockchainapproaches for documenting (mis)conduct (Cole et al., 2019; Saberiet al., 2019), use of artificial intelligence approaches (Nishant et al.,2020) and Industry 4.0 technologies such as big data (Fosso Wambaet al., 2018) and cybersecurity (Sawik, 2020) for predicting and prevent-ing the issues raised from fraud and misconduct to disruptions seempromising topics for addressing the related intersection. This can alsobe challenged since blockchains would not always lead to more trace-ability (Bischoff and Seuring, 2021). Given the dynamic developmentof digital transformation of business (Hanelt et al., 2020), this seems apromising research direction linking into multiple further topics.

    4. Supplier selection and evaluation

    Supplier selection and evaluation have been addressed taking mul-tiple forms (Miemczyk et al., 2012). Starting from green supplier selec-tion (Kuo et al., 2010), there are multiple numerical and optimisationtools (Luthra et al., 2017) that have been used as review papers illus-trate (Govindan et al., 2015; Igarashi et al., 2013; Zimmer et al.,

    3

    2016). This links into the wider debate on environmental purchasingand supplier management (Tate et al., 2012) and related managementpractices (Blome et al., 2014a). This topic now gets new impetus as aconsequence of the Covid‐19 pandemic (Mahmoudi et al., 2021), whereissues of green and resilient sourcing and shorter supply chains areaddressed, which links into sustainable supply network management(Matthews et al., 2016) and re‐evaluating supply chain objectives(Siebert et al., 2021). Therefore, supplier selection and evaluationmight also be the topic, where future development can be expected.

    5. Supplier development

    Supplier development (Krause and Ellram, 1997) played and stillplays an important role in the SSCM debate. This links to the pressuredebate (Busse et al., 2017) as well as stakeholder management (Liuet al. 2018) and shows a possible connection with mimetic pressure(Sancha et al., 2015). In line with Seuring and Müller (2008), Yawarand Seuring (2017) point out that supplier development is highly rele-vant for addressing social issues in supply chains. This is explored ingreater depth by studies pointing to the relevance of supplier develop-ment for achieving social outcomes (Yawar and Kauppi, 2018) andimproving performance (Aman and Seuring, 2021; Blome et al.,2014a). Recent developments show that supplier development (Jiaet al., 2021; Yawar and Seuring, 2020) can also be applied to addressinginstitutional voids (Parmigiani and Rivera‐Santos, 2015) and sustain-ability tensions and paradoxes (Hahn et al., 2015), which is a recentand rapidly emerging debate in the sustainability domain. Both havebeen linked to the sustainable supply chain topic. Xiao et al. (2019)explore how purchasing and sustainability managers within buyingfirms make sense of and respond to paradoxical tensions in SSCM,which is certainly a challenging issue, also reflected in further research(Zehendner et al., 2021). Staying in emerging market contexts, supplierdevelopment might address institutional voids (Brix‐Asala and Seuring,2020). Particularly, supplier development might also address what istermed the inclusion(‐exclusion) paradox (Brix‐Asala et al., 2021).The integration of farmers from low‐income countries into global sup-ply chains demands that certain standards are implemented, therebyaiming for performance improvements (Aman and Seuring, 2021).However, smallholders are hardly equipped for fulfilling the rigorousquality and safety checks and numerous requirements. Thus, standardscan create barriers for smallholders to become part of global supplychains, which are increasingly required to ensure fair wages andachieve other social objectives (Glasbergen, 2018; Valkila, 2009). Thispoints to an issue taken up in the future research section, i.e., base‐of‐the‐pyramid and emerging economy‐related research aiming at sustain-able value creation (Schilling and Seuring, 2021).

    6. Communication and collaboration

    If positive outcomes are to be achieved and more sustainable devel-opment along the supply chain is to be obtained, communication, coor-dination and collaboration with suppliers seem evident (Seuring andMüller, 2008). In the analysis of base‐of‐the‐pyramid‐related literatureagainst supply chain constructs, communication emerged as one of thecentral constructs (Khalid and Seuring, 2019). Subsequent empiricalresearch revealed a link between communication and strategic purchas-ing and technological integration with suppliers as well as purchasingperformance (Khalid et al., 2020). Both studies thereby offer insightson how essential communication with suppliers is. A different observa-tion is made in the empirical analysis by Seuring et al. (2019), where thecommunication item is mainly connected to auditing and third‐partyinvolvement and ensuring minimum standards of environmental andsocial conduct. This is in line with Silva et al. (2021), who explain: “sus-tainability is spread driven by market pressure, mainly through the dif-fusion of technical information, either by lead organisations enablers orinter‐organisational relations” (Silva et al., 2021, p.1030).

    S. Seuring et al. Cleaner Logistics and Supply Chain 3 (2022) 100016

    Turning to supply chain collaboration, similar arguments can befound; therefore, aligning supply chain initiatives pays off (Blomeet al., 2014b) and confirming the often made win–win argument. Thisseems to be one of the central aspects of communication and collabo-ration with a range of stakeholders, often linked to environmentalobjectives, such as a carbon cap and addressing trade‐offs among envi-ronmental and economic objectives (Ding et al., 2016). Such trade‐offswould link into the already mentioned tension and paradox debate(Brix‐Asala et al., 2021), where many questions are still open andresearch seems to emerge. More critical analysis on sometimes evenunforeseen outcomes of related measures would certainly be welcome(Matos et al., 2020). It also links into the two subsequent issues of riskand performance management.

    Further, the role of collaboration has evolved from the traditionaldyadic relationships (e.g., buyer–supplier relationship) to triadic andmyriad relationships (Mokhtar et al., 2019) in order to integrate stake-holders as discussed in the previous sections. Chen et al. (2017) com-prehensively elaborated this diversity through a list of supply chaincollaboration practices worth further studying to understand their con-tribution to the environmental, social and economic performances.Touboulic and Walker (2015a) highlighted the importance of under-standing how companies from different industries collaborate toachieve improved sustainability performance in supply chains, whileBenstead et al. (2018) encouraged horizontal collaboration with NGOsto improve sustainable performance while overcoming uncertaintiesfaced during legislation changes. Hence, moving beyond the bound-aries of traditional supply chains and collaborating with non‐traditional supply chain actors can spark new avenues to drive innova-tion (Aman and Seuring, 2021) and improve sustainability perfor-mance in supply chains.

    7. Risk management

    Based on the links to environmental and social risks in supplychains (Freise and Seuring, 2015), it can be expected that there willbe an ongoing debate analysing multiple impacts from disruption(Jabbarzadeh et al., 2018) to external shocks and extreme conditions(Sodhi and Tang, 2021) linking to the aspects mentioned for supplierselection. It is almost hard to point to a specific issue, as the researchon sustainable supply chain risk is multifaceted (Lima et al., 2021b;Rebs et al., 2018). The intersection of sustainability and resilience(Ivanov, 2018) would be particularly relevant for this analysis, againlinking into the Covid‐19 aftermath topic. It can be expected that thisstream of research will continue further, which seems well justifiedgiven changing global conditions and open research issues in supplychain resilience (Wieland and Durach, 2021). These changing globalconditions also link digital transformation to environmental and socialrisks. In this regard, both appreciation and criticism are expected if wecombine research from the emerging and the developed markets.

    8. Performance management

    Searching for performance management in a supply chain contextgives an almost endless number of hits. The challenge seems to behow this performance would be comprehended. As mentioned already,Seuring and Müller (2008) point to environmental and social stan-dards serving to set minimum requirements that need to be monitoredalong the supply chain. Such standards can have a positive impact onthe communication of related objectives (Laihonen and Pekkola,2016), given that environmental and social standards are fulfilled(Seuring et al., 2019). A critical account is presented by Lima et al.(2021a), who ask whether organic standards are “socially just, ecolog-ically regenerative, economically robust, and politically inclusive”(Lima et al., 2021a, p. 89), thereby being linked to the already men-tioned question on how sustainable supply chains can be managed inan inclusive manner (Brix‐Asala et al., 2021).

    4

    This links into the wide debate on supply chain governance struc-tures in global supply chains (Koberg and Longoni, 2019) and pointsto different governance structures (Formentini and Taticchi, 2016).Future SSCM research may adopt different theoretical frameworksand critical perspectives to further theorise the relationship betweengovernance structures and sustainability outcomes. In the agri‐foodsector, early influential research suggested that private and neoliberalforms of governance can provide firms with a competitive advantage,but the social and environmental protections they offer are often min-imal (Guthman, 2007). These reflections concerning the businesspotentials and complications of market‐driven governance structurescould also be brought into the realm of manufacturing, electronics,retail, logistics and more, which received little scholarly attentionwhen compared to agri‐food research (Wahl and Bull, 2014). An addi-tional link is evident in the already covered multi‐tier challenge, wherefirst‐tier suppliers and focal companies have a formal contract, whichis usually not the case with second or third‐tier suppliers, also raisinggovernance‐related issues. This also then links to the emerging econo-mies debate where governance structures are often criticised. Besides,they also serve as second‐ or third‐tier suppliers in some of theresource‐based global supply chains. As Silvestre (2015, p. 156) men-tioned, “although globalisation is a trend, natural resource‐based sup-ply chains are often more geographically bounded and susceptible tolocal social demands than other supply chains”. Therefore, considera-tion of governance structures and sustainability outcomes offers inter-esting research directions.

    More conventional forms of performance management and mea-surement in sustainable supply chains addressing economic criteriaand particularly the intersection to environmental and social issuesstill offer an interesting research topic. For instance, Sudusinghe andSeuring (2020) addressed this intersection between social and eco-nomic performance in apparel supply chains while hinting at theimportance of future research to explore the scholarly debate relatedto the direction of causality on whether socially sustainable supplychains achieve economic performance or vice versa.

    9. Sustainable products and services

    The sustainable products are mentioned here for completeness. AsSeuring and Müller (2008) point out, the supplier and process‐relatedaspects are linked to the product and outcome‐related ones. Whilethey are often kept apart in the academic debate, they are clearlyinterrelated in real‐world examples. The link to sustainable new pro-duct design and related capabilities is already established (Gmelinand Seuring, 2014), but still a current stream of research(Guimarães et al., 2021). It seems nearly impossible to define a sus-tainable product in line with hardly any supply chain being truly sus-tainable (Pagell and Shevchenko, 2014). Hence, this links into thedebates on life‐cycle management (Benoît et al., 2010), which playsa role in supply chain management. With the evolution of the tech-nologies, digitalised supply chains integrated with Industry 4.0 tech-nologies such as additive manufacturing (3D printing) (Mellor et al.,2014), cloud computing (Queiroz et al., 2021), the internet of things(Da Xu et al., 2018) have the potential to positively impact productlife‐cycle management. Therefore, this topic needs furtherinvestigation.

    Moving on from these lines of reasoning, several other debates areemerging in the SSCM domain. Such a list can only look at selectedtopics, which are based on our admittedly personal observations.

    4. How to move on in SSCM?

    For looking at how to move on, we build on the logic of the theory,method, and empirical field as three distinct aspects of academicresearch in the social sciences (see Seuring et al., 2021).

    S. Seuring et al. Cleaner Logistics and Supply Chain 3 (2022) 100016

    1. Theory

    Touboulic and Walker (2015b) opened up the debate of what theo-ries are used for in SSCM, which is in line with the demands raised byCarter et al. (2015). There are multiple facets of theories borrowed intoSSCM, where it is hard to present a list of what might be relevant. Thedynamic capability approach (Carbone et al., 2019; Gruchmann et al.,2019; Siems et al., 2021) should be one candidate for comprehendingchanges in the supply chains, both on explaining what is happeningbut also predicting future directions. Given the constellation of theorieswithin supply chain management, marketing and management, werefer the reader to Gligor et al.’s (2019) 217 theoretical approaches thatcan help supply chain scholars explain the phenomena of interest.

    In the previous sections, we briefly outlined several theories, suchas institutional theory or sustainability tensions and paradoxes. Thisshows how different theoretical streams inform SSCM, a line of devel-opment that is expected to continue. The paper titled “dancing the sup-ply chain” (Wieland, 2021) points the way forward in broadening ourcomprehension of supply chain management.

    2. Methods

    The field seems to be dominated by either modelling research orempirical research, where Rebs et al. (2018) even show that there isnot much exchange among these two substreams. This is a clear pointof criticism, as colleagues from other management domains would notdistinguish this. Therefore, it is a kind of plea to all of us writing in thefield not to ignore development in SSCM just because they use a differentmethodological approach. More studies building on behaviouralresearch methods would certainly enrich the comprehension in the field.

    The critique of Carter and Washispack (2018) made for literaturereview papers would also hold for other cases: without a sound theo-retical grounding, yet next study in a dynamic but established field isnot expected to make a difference.

    One core challenge in supply chain management research is datacollection on multiple tiers of the supply chain. This is still rarelyimplemented, as it is challenging to access focal companies, suppliers,and customers. So, research will be very well received if data on alonger part of the supply chain can be presented.

    To illustrate some issues appearing on the intersection of theoryand method, we refer to recent calls for theorising the intersectionbetween circular economy and supply chain management, often calledcircular supply chains (Farooque et al., 2019). Some challenges inapplying empirical methods might hamper the development of soundresearch and theory. We share that “empirical evidence of non‐linearproduction benefits is sparse” (Sehnem et al., 2019), primarily dueto the limited number of organisations implementing circular practicesrather than recycling and managers’ time constraints to participate inresearch (Sehnem et al., 2019). Overall, we regard the latter issue as arecurring trend within supply chain research, where some firms mightsee no “obligation” to participate in, for instance, case study researchunless they could benefit from it in the short term. While an effectivesolution to overcome this issue may vary across different disciplinesand fields of research, we insist that “nothing is quite so practical asa good theory” (van de Ven, 1989).

    Nevertheless, to enlighten the profession of management throughgood theory, we believe it is highly crucial to establish, among otherthings, collaboration with practitioners, e.g., through workshopswhere both practitioners and scholars can benefit from knowledgesharing. Other scholars also stress the role of adopting critical,engaged research to embrace transformative opportunities and thepower to re‐imagining issues in supply chain management and thebuilding of novel theory (Touboulic et al., 2020). Notable examplesin this regard include but are not limited to experimental actionresearch, emancipatory and participatory research, narrative inquiries,and reflexive deconstruction through collaborative inquiry.

    3. Empirical fields

    Looking at empirical fields, there are always new topics coming.Structuring the debate, we group this into the three dimensions of sus-tainability logic and discuss some issues on the environmental andsocial sides. As before, there is no assumption that the lists would becomplete.

    a) Environmental issues

    The driving issue on the environmental side receiving a lot of atten-tion at the moment is carbon emissions and climate change (Ghadgeet al., 2020). Given the broader debate on planetary boundaries, manyenvironmental issues have hardly been connected to supply chainmanagement, posing many challenges (Clift et al., 2017). For instance,looking at biodiversity, the use of phosphorus and nitrogen has hardlybeen linked to the supply chain debate. This would allow to explorenew environmental challenges, which can serve as a test on whetherdeveloped constructs and concepts would also hold in this domain.

    A different kind of logic is evident in the circular economy and cir-cular supply chains debate, which is gaining more attention (Batistaet al., 2018; Calzolari et al., 2021). Related models of managing supplychains will be needed to avoid the overuse and exploitation ofresources.

    b) Social issues

    Following an initial slow start, the social side is not well covered(Yawar and Seuring, 2017). There are still many issues left, wherebase‐of‐the‐pyramid (Brix‐Asala et al., 2021; Khalid and Seuring,2019) and emerging economy (Silva et al., 2021) related topics war-rant more research. In this regard, a range of social issues is addressed.So, there will be ample research opportunities looking into, e.g., socialand sustainable value creation (Lashitew et al., 2021) and aiming at“good supply chains” (Carbone et al., 2019).

    A particularly relevant topic is modern slavery (Caruana et al.,2021), which moved into the focus of supply chain research (Coleand Shirgholami, 2021; Gold et al., 2015). In line with the argumentjust mentioned on the environmental side, in this context, existing con-cepts can be put to the test and advance knowledge accordingly.

    c) Digital transformation toward sustainability

    The other core theme driving business and management relatedresearch forward at the moment is the briefly bypassed digital trans-formation (Hanelt et al., 2020; Klos et al., 2021), which seems highlyrelevant for reaching a sustainable future, but has not been addressedmore often (Liu et al., 2020). Hence, topics such as blockchains (Coleet al., 2019; Esmaeilian et al., 2020; Saberi et al., 2019), artificial intel-ligence (Kuo et al., 2010; Pournader et al., 2021), Industry 4.0 (Baget al., 2018; Yadav et al., 2020), and its related technologies includingbig data (Fosso Wamba et al., 2018), additive manufacturing (Ford andDespeisse, 2016; Oettmeier and Hofmann, 2016) offer ample researchopportunities. Linking this to environmental and social outcomes andcritical assessments of their impact would offer changes for driving thecomprehension of SSCM forward and enabling sustainable value cre-ation (Schilling and Seuring, 2021), thereby advancing the lines ofresearch envisioned in the extant paper.

    5. Conclusion

    This paper operationalised one of the frameworks of SSCM that hasimpacted the field (Seuring and Müller, 2008) which serves as a foun-dation to reflect on developments in the field. First, nine conceptualelements of SSCM are identified to address theory development: (1)

    S. Seuring et al. Cleaner Logistics and Supply Chain 3 (2022) 100016

    stakeholder management, (2) pressures and incentives/drivers andbarriers, (3) multi‐tier supplier management, (4) supplier selectionand evaluation, (5) supplier development, (6) communication and col-laboration, (7) risk management, (8) performance management and(9) sustainable products. Second, lines of research were illustratedfor each field to elaborate on the current status of the field and,thereby, pointing to future research directions. While only selectedissues could be covered in such a manner, the paper outlined manydevelopments and pointed to future research directions. Both environ-mental and social sides still have much to offer on several issues to beaddressed given the many needs people and planet have for their sur-vival and further sustainable development.

    Third, the paper reinforced the need for a sound choice and justifi-cation of theory, method, and empirical field to advance future SSCMresearch. Although each element has its own underlying complexities,carefully planning the respective research process is paramount. Thus,planning and reflection are crucial processes that require SSCM schol-ars to critically theorise the phenomena of interest while consideringdisruptive risks, such as climate change and biodiversity loss. Theoris-ing in SSCM can elucidate and explain supply chain management phe-nomena toward economic, environmental, and social sustainability.The paper highlights that hot topics such as the circular economy, dig-ital transformation and base‐of‐the‐pyramid supply chains, to name afew, still require careful scrutiny and theorising in SSCM. This is par-ticularly important to enable future SSCM research “to tackle (…)grand societal challenges” (Wickert et al., 2021, p. 297) such asexceeding planetary boundaries and social issues in underdevelopedeconomies in order to create impact on various levels.

    Abstract

    Purpose – The purpose of this paper is to critically assess current developments in the theory andpractice of supply management and through such an assessment to identify barriers, possibilities andkey trends.

    Design/methodology/approach – The paper is based on a three-year detailed study of six supplychains which encompassed 72 companies in Europe. The focal firms in each instance weresophisticated, blue-chip corporations operating on an international scale. Managers across at least fourechelons of the supply chain were interviewed and the supply chains were traced and observed.

    Findings – The paper reveals that supply management is, at best, still emergent in terms of both theoryand practice. Few practitioners were able – or even seriously aspired – to extend their reach across thesupply chain in the manner prescribed in much modern theory. The paper identifies the range of keybarriers and enablers to supply management and it concludes with an assessment of the main trends.

    Research limitations/implications – The research presents a number of challenges to existingthinking about supply strategy and supply chain management. It reveals the substantial gaps betweentheory and practice. A number of trends are identified which it is argued may work in favour of betterprospects for SCM in the future and for the future of supply management as a discipline.

    Practical implications – A central challenge concerns who could or should manage the supplychain. Barriers to effective supply management are identified and some practical steps to surmountthem are suggested.

    Originality/value – The paper is original in the way in which it draws on an extensive systematicstudy to critically assess current theory and current developments. The paper points the way fortheorists and practitioners to meet future challenges.

    Introduction“Supply management” can be viewed as both an emergent field of practice and anemerging academic domain. Neither perspective is fully mature but each hasconsiderable promise. The future progress of each will be enhanced and indeed isultimately dependent upon the other. Hence, the purpose of this paper is to take stockof developments in theory and practice to date and to identify barriers and possibilities.Moreover, given the off-remarked acknowledgement of the crucial importance of thebehavioural and people dimension but the relative neglect of this in any substantiveform, we give special attention to this aspect. Supply (chain) management is ultimatelyabout influencing behaviour in particular directions and in particular ways. Theunderlying logics, drivers, enablers and barriers merit and require close attention.

    A number of analysts have already sought to comprehend and substantially redrawthe boundaries of, and the essential nature of, this domain of theorising and practice. Forexample, in one of the more coherent and developed attempts at a reconceptualisation,Harland et al. (1999) present the case for a new expanded body of knowledge and field ofpractice which they suggest should be labelled “supply strategy”. The rationale behindthis is the intent to improve upon the more limited concepts of “operations management”and “operations strategy”. They suggest that supply strategy can embrace logistics,operations management, purchasing and supply management, industrial relationshipmarketing and service management. But, they suggest it is not just an aggregation ofthese: the underpinning idea is to exploit “relational strategies” in a holistic way.

    When approached in such a way the field merges imperceptibly into the strategicmanagement literature concerned with strategic partnerships (Storey, 2002). Strategicpartnerships can be formed “horizontally” and “vertically” – the latter being expressionsof supply or channel relationships. Closer bonds are:

    . . . what separates partnerships from a more transaction based set of exchanges which arelimited in scope and purpose (Mohr and Spekman, 1994, p. 140).

    The essential point is to identify and describe a domain of theory and practice wherethere is potential for some additional gain by reconceptualising it in a particular way.The important idea captured at least in part by “supply strategy” (or “strategic supplymanagement”) is that a mode of thinking and action which encompasses, and seeks toexploit, interlocking relationships could potentially be used as a powerful lever forcompetitive advantage (Ketchen and Giunipero, 2004).

    Drawing upon an extensive three year research project which involved a number ofsupply chains encompassing a total of 72 companies in Europe, we seek in this paper toshed new light on the theory and practice of strategic supply management. We willargue that while there is an emerging body of theory which ostensibly offers a relativelycoherent and compelling prescriptive narrative, predominant practice is at considerableodds with this conceptualisation. We will also reveal the substantial reasons why such adiscrepancy exists and why it is likely to persist in most value chains for some time tocome. It is certainly possible to find transient instances of impressive practice; but wemaintain and show that these are vulnerable to erosion. Thus, while the field of supply(chain) management has promise in terms of its idealist allure, in practice it will remainunder-developed unless new modes of skilful intervention are developed.

    If supply chain management is to mature as a discipline there needs to be furtherprogress in clarifying its domain, its central problems, its core components, its theoriesand its theoretical map (Tranfield and Starkey, 1998; Croom and Romano, 2000; Storeyet al., 2005). In addition, we need to attend to how this work in theory-building can beassisted by drawing on the study of practice. Under this latter heading we include mostcentrally how managers’ own cognitive maps, expectations and goals are constitutedand what barriers stand in the way of the realisation of the idealistic notions such as“seamless end-to-end pipeline management” (Storey et al., 2005). Thus, a furtherrefinement of the objectives of this paper can be stated thus to:

    . identify and clarify the core conceptual building blocks of the emergentdiscipline;

    . examine these conceptual building blocks in relation to empirical data in order todevelop a view on the fit between theory and practice; and

    Theory, practiceand challenges

    755

    . identify the future challenges that these revealed outcomes pose for supply chainmanagement as both a practice and a discipline.

    The paper is structured in four parts. The first summarises the key elements in supplychain management theory; the second explains the methods by which we investigatedsupply chains in practice; the third identifies some of the crucial features of supplychain management practice; and the fourth discusses the implications of thecomparisons between theory and practice. In particular, this final section identifies keyissues meriting special attention in the future.

    The theory of supply managementIt is apparent that much of the focus in the increasingly voluminous literature onsupply strategy, operations strategy and supply chain management is directed atmeaning making. Often this comprises assertions about what it essentially “is”. Theprecepts of SCM as currently portrayed are a mixture of three elements: description,prescription and the identification of alleged trends.

    DescriptionDebates here relate to scope and focus. Some academics openly declare that they usethe terms supply chain management and purchasing “synonymously” (Stuart, 1997).Pragmatically there may be much to commend this but the identification with onefunction and one process seems to miss much of the idea of supply chain or networkmanagement. Others evidently have a more expanded notion in mind, for example, thelean supply approach focused on the “purchasing activities of vehicle assemblers andthe supply activities of the component (and component system) manufacturers”(Lamming, 1996, p. 183). Accordingly, Lamming argues, for the merits of the broaderconcept of “supply management”. Some purchasing specialists see SCM as aboutdeveloping relations with suppliers (Giunipero and Brand, 1996), while others say thatgood supplier management is not enough; there is an additional requirement for awider, more integrated, all-encompassing perspective embracing all processes fromsourcing through make and transportation and on to merchandising to final customers(Davis, 1993).

    In the battle over definitions and descriptions, part of the agenda is undoubtedly anattempt to re-position functions and quasi-professions such as operations managementand logistics. We return to this point later. Rather than try here to determine the preciseconstruct, we acknowledge the value of adopting a constructivist approach – that isexploring how actors themselves engage in meaning-making. Through this latterapproach we have the opportunity to explore how relevant actors construe their primeobjectives, the scope of their activities, the allocation of responsibilities, the barriers todesired practice and the enablers. Accepting the value of this approach does not denythe contribution of theory and model-building of the kind more conventionally foundwithin supply management.

    PrescriptionProblems arise when the shift from description to prescription is relatively covert.Beneficial attributes are often attributed to certain features. For example, one definitionsuggests that:

    IJOPM26,7

    756

    . . . any chain or network connected through electronic means can be considered virtual if itfacilitates efficient and effective flows of physical goods and information in a seamlessfashion (Chandrashekar and Schary, 1999, p. 27).

    Some prescriptions stem from observed superior practice in particular domains.The IMVP prescription deriving from Toyota and its suppliers leading to the leanproduction formula is arguably of this type. Another example might be the prescriptionfor mass customisation and agility (Pine, 1993; Goldman et al., 1995; Meier andHumphreys, 1998).

    Prescription can be valuable, but for the discipline to advance there needs to be alsorigorous testing – and serious exploration of the causes of failure.

    Trends identificationThe literature on supply chain management tends to move rather imperceptibly betweendescription, prescription and trend identification. Key trends which have been identifiedinclude, most notably, “cooperation” rather than competition, a shift from the“antagonistic” model to a collaborative model (Matthyssens and Van den Bulte, 1994;Carr, 1999), the increasing use of supplier-evaluation tools (Carr, 1999), a trend towardssupplier management, and so on. While the alleged trends may be similar, different kindsof assessments are sometimes made. Some authors suggest an irresistible trend whileothers note the relatively limited take up to date (Skjoett-Larsen, 1999; Kemppainen andVepsalainen, 2003).

    Another facet of the trends dimension is the concern with the “impacts” of SCM onvarious functions such as purchasing (Andersen and Rask, 2003; Wisner and Tan, 2000),the impacts on suppliers required by retailers to replenish stock based on actual sales(Abernathy et al. 2000), and the increasing use of tools and techniques such as “QuickResponse” (QR) and “Efficient Consumer Response” (ECR). A trend, possibly mainlyrestricted to the auto industry, is towards a pattern of differentiation in the supply chainwith, for example, a few “system integrators” at first tier supply level (Senter and Flynn,1999).

    While most trend analysis implies progress – for example, Hines et al. (2004) –Fisher (1997) claims that despite all the technology and the new techniques, supplychain performance in many instances has “never been worse”. The reason, he suggests,is that managers lack a framework for determining which methods are appropriate.This implies the need for managers to adopt far more of a contingent rather than a“best practice” approach. It further suggests a need to fit supply chain characteristicsto product strategy. Similarly, partnership may not always be the right approach inevery circumstance (Lambert et al. 1996).

    The underlying claimed “trend” is that supply management consciousness isaccelerating up the corporate agenda and there does appear to be some evidence forthis. For example, many companies have appointed supply chain directors and therehas been talk of competition between supply chains rather than simply competitionbetween individual firms (Christopher, 1998). Perhaps even more prevalent has beenthe trend towards the conscious examination and rationalisation of supplier networksand the development of “collaborative” or “partnership” relationships between buyersand suppliers (Balakrishan, 2004). Such initiatives have come to be seen as of strategicsignificance by general managers rather than simply tactical gains by functionalspecialists (Storey, 2002).

    Theory, practiceand challenges

    757

    But these examples point to a problem for supply management as a potentialdiscipline. There is already a reasonably well-developed field concerned withbuyer-supplier behaviour (or purchasing) and this has its own set of core concerns.Many of these concerns relate to the choice of supplier, managing relationships withsuppliers and so on (Monczka and Petersen, 1998). But this sub-field rarely attends to thewider vision of the supply chain management concept with its notions of end-to-endpipeline management and the seamless, efficient, flow of information andmaterials/products through the whole network or chain – from source, through make,and on to delivery to the end customer. Thus, while there are certainly overlaps betweenthe dyadic buyer-supplier behaviour domain and the supply chain (or network) conceptthere are also some substantial points of difference.

    So, in the light of the discussion so far, where does the emergent discipline of supply(chain) management stand today? Academic disciplines normally have core sets ofconcerns or problems, but the variability and uncertainty within supply managementof its core concerns is one of the problems it faces (Ho, 2002).

    Our review of the literature on supply chain management suggests that the field ischaracterised by idealism and fragmentation. It uses overlapping terminology which isin turn drawn from multiple-disciplinary bases. Croom and Romano (2000) show how11 different subject literatures – including, for example, purchasing, logistics,marketing and organisational behaviour – have contributed to the supply chaindomain. Despite recent attempts to map the terrain (Chen and Paulraj, 2004; Giannakisand Croom, 2004; Mills et al., 2004), the field remains disparate. None the less, whencomparisons are made across the literatures there are some basic shared “visions”which help form an underpinning “big idea” – or a number of interlocking big ideaswhich help constitute and describe supply chain management. In Table I, we drawupon a wide literature in order to enumerate and categorise these core ideas.

    This dichotomous representation suggests of course a rather stark set ofalternatives. It nonetheless represents widely held assumptions about the “paradigmshift” to partnering, strategies of co-operation, and SCM.

    The unit of analysis itself – the supply “chain” – is itself a matter of somecontention. Sometimes the internal supply chain is seen as a suitable arena;alternatively the dyadic relation between buyer-supplier is the unit of analysis, or achain or a wider network. Then, within the confines of any of these, intervention maybe directed at efficiency improvements of existing processes, the redesign of interfaces,or (more rarely one assumes) radical restructuring of the supply chain components(De Treville et al., 2004). Critiques of the discipline of supply chain managementsuggest that it is atheoretical and relies too much on prescription and description(Cox, 1999; Croom and Romano, 2000).

    As Table I suggests, there are a number of interlocking ideas and propositionswhich constitute the theory and prescription of supply management. The centralunderpinning ideas relate to alignment and integration. Whether sub-components orservices are made or bought, the prescription is that the interface between eachvalue-add phase should be subject to careful planning and management. Otherimportant related concepts include core competences, supplier segmentation, strategicpurchasing and supplier integration (alignment; supply-base management, andreduced supplier base). Other fundamental ideas include win-win relations betweenpartners in the chain, goal congruence, avoidance of opportunistic behaviour, supplier

    development, strategic alliances, variants of vendor managed inventory (VMI), and thesharing of risks and rewards. Beyond these core concepts, there are some points ofdifference depending on the particular approach to supply chain management that isproselytised.

    Make or buy is a crucial preconditioning decision which determines the need for theamount of external relationship management. How much difference it really makeswhether the supply chain extends across different ownership structures rather than asingle vertically integrated organisation is a moot point and is yet to be subject tosufficient systematic empirical investigation. It would be fair to contend that thequestion of where to locate the decoupling points in order to address issues ofreplenishment exists relatively independently of the ownership make/buy decision. Thewhole issue of relationship development across partners is however highly connectedwith the nature of the independent units. But again, the precise nature of the practicalmanagerial challenge to forging win-win collaborative partnerships across the supplychain irrespective of whether the partners are officially internal or external to the focalorganisation is itself also relatively under-explored. Some analysts focus entirely oninternal tensions, for example, between the marketing and logistics functions (Ellinger,2000), while others ignore this and focus only on the external (Cox, 1999).

    Much of the theory in supply management is based on idealised schemas of optimalroutes and quantities for demand fulfilment when considered from a whole-network orchain perspective. These idealised schemas may vary in detail when advanced byvarious proponents but there are a number of relatively common elements. Thesecommon elements are constituted by a number of technical possibilities. Table IIsummarises the characteristics underpinning the ideally managed supply chain.

    Nestled beneath the dominant big idea of supply chain management as a whole(i.e. the notion of an aligned and possibly integrated network of processes from endcustomer to source and design of product and service) are a number of sub-theories.These include for example lean (Womack et al., 1990), agile (Goldman et al. 1995) andmarket segmentation (Gattorna, 1998). The latter leads to the concept of adifferentiated approach to supply chain provision (Fisher, 1997). These ideas havefuelled recent development (Cigolini et al., 2004; Lee, 2002; Randall et al., 2003) andcritique (David et al., 2002).

    Usually remaining implicit in the core component ideas shown in Tables I and IIand in the sub-theories are a number of issues and activities. These can be understood

    1 Seamless flow from initial source(s) to final customer2 Demand-led supply chain (only produce what is pulled through)3 Shared information across the whole chain (end to end pipeline visibility)4 Collaboration and partnership (mutual gains and added value for all; win-win; joint learning

    and joint design and development)5 IT enabled6 All products direct to shelf7 Batch/ pack size configured to rate of sale8 Customer responsive9 Agile and lean

    as a series of mainly unanswered and yet crucial questions: who is responsible for“managing” these activities? Just because supply chains may exist it does notnecessarily follow that they are actually managed. Even if they are managed in parts, itdoes not necessarily mean that they are managed across the whole spectrum. How dothe actors reach-through the various echelons in order to achieve the desired alignedgoals? What levers do they pull? What barriers do they encounter and how do theyseek to overcome these? These particular questions are especially pertinent given that,as has already been noted, most definitions of the field are based on metaphors(pipelines, chains, networks) rather than “objective entities” (Saunders, 1994).Managing objective entities is difficult enough, but how do managers cope with andengage with the metaphorical forms? These, and similar questions, which have so farbeen massively neglected in the literature to date, formed the heart of our empiricalresearch project.

    Researching current supply practiceAs we said at the outset, one of our central objectives was to examine the theory andpractice of supply chain management. Hence, to complement the summary of supplychain theory in the previous section we set out to compare that with contemporarypractice. In order to map current practice we designed a large study which explored arange of supply chains across multiple echelons. Notably, in the core part of thestudy we delved into the supply chain management practices of six “blue chip” firms(and their suppliers and customers), which we will refer to as Pharmaco,Householdproductsco, 4PLDrinks, TelevisionCo, ElectronicsCo and 4PL Electronics.These cases were selected on the basis that, according to information in the publicdomain, these players were likely to exhibit leading-edge sector practice. A summaryof the six case environments is shown in Table III.

    Pharmaco is a large manufacturer and retailer of pharmaceuticals and relatedhealthcare products; HouseholdproductsCo is a manufacturer of a range of skincareand beauty products; 4PL Drinks is a division of a global logistics corporation whichspecialises in third and fourth party logistics in partnership with a number of alcoholicand non-alcoholic drinks manufacturers; TelevisionCo designs and makes a wholerange of domestic electrical goods including televisions of both high and lowspecification; ElectronicsCo designs and supplies sophisticated telecommunicationsnetwork equipment; and 4PL Electronics is a joint venture between a major logisticsprovider and a computer equipment manufacturer. As the sales figures in the thirdcolumn of Table III reveal, these were all substantial businesses. The companies listedin the fourth column indicate the number of supply chain partners that were alsoresearched. The final column shows the number of interviews conducted in each case.

    Interviewees were selected according to the key supply chain processes they managedin each of the firms. We were primarily interested in the evidence provided by directorsand middle managers covering all supply processes (plan, source, make and deliver).Interviews were conducted in the UK, Ireland, the Netherlands, Germany and Italy.The duration of each interview was usually between one and a half hours to two hours.All interviews were recorded and transcribed. Some key informants were interviewedon multiple occasions. We undertook extensive site tours and collected large amountsof documentary materials relevant to SCM. The project commenced in 2001 andcontinued into 2004. The scope of the six supply chains that we studied was plotted,based on an adapted version of the New and Payne (1995) supply chain taxonomy.This is shown in Figure 1.

    From this body of research we have started to compile a picture of current supply chainpractice, and have identified a number of organisational and behavioural barriers to therealisation of the more idealistic depictions of the “seamless, end to end” chain that should beresponding to customer demand. Despite the considerable interest among practitioners inthe idea of supply chain management – and this interest was certainly found among manyof our respondents – its practice usually differs markedly from the idealised prescriptionsidentified in the previous section. The research into practice also helped us identify thenature of the more significant (real-life) trends in supply chain management today.

    We interrogated supply chain practice through a series of four fundamental questions:

    (1) Who was “managing the supply chain” in practice? (That is, which individualsor groups are actually engaged in such practice?)

    (2) What type of “supply chain” activities were they managing?

    (3) What were the key enablers and inhibitors to this process?

    (4) What external factors were driving the strategic imperative of supply chainmanagement?

    This kind of dual theoretical and empirical approach is in tune with the point made byCroom and Romano (2000, p. 75) that:

    . . . the inductive-deductive dichotomy is best addressed through the constant reflection ofempirical against theoretical studies.

    Results: supply chain practice(s)The description of results is structured into four-sections, each one capturing thefindings from one of the fundamental questions used for exploring the supply chain.

    Who is “Managing” the supply chain?The holistic concept of “seamless, end to end” supply management – as distinct from aseries of units or functions engaging in sub-optimal behaviour – is clearly laudable.However, it implies some considerable effort to reach through the supply chain: upstreambeyond the first tier suppliers, and downstream beyond a focal firm’s customers – theso-called “arcs of integration” (Frohlich and Westbrook, 2001). Alternatively, it wouldrequire an unusual degree of co-ordination between tiers. Rarely asked by the proponentsof such “integrated” supply chains is who precisely is meant to be doing this “managing”?In practice we found very few instances where any such active agent could be identified.The modal pattern was a number of practitioners who sought to manage parts of thesupply chain. These parts were normally circumscribed by legacy practice and also by theexpectations of other senior colleagues who defended “their” functional areas ofresponsibility. As the results in Table IV demonstrate, it was still more common to have alogistics director than a supply chain director – usually with a focus on outbound logistics.

    With the shift to outsourcing there had been a significant reduction in the scale andscope of in-house manufacturing facilities. Where these remained, the procurement ofparts was predominantly a procurement and/or purchasing function responsibility, theexception being TelevisionCo, where supplier base management had been recentlyintegrated into their already cross-functional, market-orientated supply teams.Manufacturing and assembly operations were managed by separate manufacturingfunctions. Normally, even people with the title “Supply Chain Director” did not actuallymanage the whole chain nor did they usually expect, or seek, to do so. They wereconfined to inward or outward logistics. In manufacturing their writ rarely extended toproduction planning and in retail they were usually not able to interfere too strongly inthe affairs of the trading directors.

    Supply chain theory would suggest that the supply chain should be managed fromend-to-end. Our research found very few examples of this but it did illuminate the barriersto its achievement in practice. There were one or two instances where very senior directorscarrying multiple responsibilities were able to transgress these norms but these wereexceptional. Even where 3PL or 4PL companies were hired to take charge of supply chainmanagement they tended to restrict their activities – or have them restricted – to limitedsegments of the chain. Even the tightly-coupled logistical operations between 4PLCoElectronics and their customer did not include the provision of information about productsin the process of manufacture – the first alert was given when a product was ready to beshipped from the factory gate. Management of the supply chain was analogous to a relayrace, with responsibility being passed from one company of actors to another, asillustrated by the array of management mechanisms found.

    Table IV.Supply chain“management”mechanisms

    IJOPM26,7

    764

    Scope of managed supply chain activitiesReaching out across the supply chain and “interfering” in suppliers’ operations wasstill relatively unusual. Exceptions related to major third party or sector-levelinitiatives such as ECR in supermarket retailing – though even these appeared to belimited to a focus on a few strategically significant first tier suppliers. The assumptionin some of the literature that supply chains are managed by powerful customers whoinfluence suppliers to conform may be broadly correct in the motor industry wherethere are a few international large assemblers, but it is a generalisation that does notapply in many other sectors. Indeed, in many instances the reverse may hold true(Bates and Slack, 1998). Even “in-sector” ECR generalisability is problematical. Forexample, our case research revealed clear “push backs” even from the champions ofECR: powerful brand holders sometimes resisted customer-led attempts at supplychain management.

    Despite this evident lack of holistic SCM, we did find evidence of internally-focusedintegration attempts, particularly within globally dispersed supply chains. Such effortstended both to simplify control, whilst reducing costs and cycle times within internallogistics activities. For example, TelevisionCo had embargoed any more than twocross-continent airfreight moves during component manufacturing operations whichwere distributed around the globe.

    Attempts to improve internal functional co-ordination ranged from the appointmentof senior managers with designated responsibilities to the nomination of operationalindividuals with specific accountability for selected boundary-spanning activities.Between these extremes, the institution of formal cross-functional teams was used bysome to improve pipeline integration.

    In certain cases, sophisticated key performance indicators (KPIs) were agreed andmonitored between SC partners. Often in the form of balanced scorecards, these measureswere weighted to drive SC practice in a particular direction. Customer-orientated measureswere balanced against internal priorities. The weaknesses of such formalised performancemeasurement systems were compensated for by pragmatic exception policies.

    Both ElectronicsCo and TelevisionCo produced (among other things) two majordifferent products: on the one hand, “off-the-shelf” products, and on the other “fullycustomised systems”. Off-the-shelf products tended to be high volume, low variety andlow value items that would flow through the logistics infrastructure (including a rangeof distribution channels) to the end customer. Fully customised systems, on the otherhand, were very high value, highly customised systems made and, in the case ofElectronicsCo installed, to specific customer requirements. ElectronicsCo employedproject managers to ensure that the systems were installed to customer requirementsboth in terms of specification and time-line, and they even set-up dedicated warehousesaround the world to facilitate installation as required. The scope was similar forHouseholdproductsco supplying washing and bathing products to a wide range ofretail customers. However, the main difference here was that Householdproductsco didnot have contact with the end consumer. The narrowest (though paradoxically themost clearly “managed”) scope was the 4PLElectronics supply chain. The scope waslimited to the outbound logistical operations of their close partner in Europe. This 4PLjoint venture company did not even have information about products in the process ofmanufacture – their first alert was when a product was ready to be shipped fromthe factory gate. In consequence of the typically constrained scope of intervention

    Theory, practiceand challenges

    765

    the notion of “seamless end-to-end pipeline management” was far beyond actualpractice – and indeed some distance even beyond aspirations.

    Enablers and inhibitorsThe research found that a number of factors can either serve to enable or inhibit supplychain management depending on the context and the way in which the factor is utilised.The case research identified three core enablers and inhibitors, the understanding ofwhich is central to turning supply chain rhetoric into reality. These are: transparencyof information and knowledge; supply chain behaviour; and performancemeasurement. The results in relation to each are considered in turn.

    Transparency of information and knowledge. Most of our cases illustrated a moveaway from forward prediction based on short-term, EPOS data. Rather, consolidatedanalysis of base trends over the medium-to-long term were used to provideforward-looking forecasts. These were then overlaid with promotional activities, anapproach adopted, for example, by a shared customer of Householdproductsco and 4PLDrinks.

    When judged in these terms we found, at best, pockets of good practice rather thanwhole-firm exemplars. Rich information was largely found to be restricted tospecifically identified users in particular relational contexts. For example, extendedcollaborative planning, forecasting and replenishment practices had been instigatedwith one internal customer within one of the market-orientated supply teams atTelevisionCo. Even where this occurred, the persistence of such privilegedarrangements was vulnerable to erosion, revision and withdrawal. In another case, asupplier to Householdproductsco had championed a Supplier Managed Inventorysystem with their major customer. Replenishment activities were driven by customerproduction schedules. The customer, however, seemed keener to abandon the systemthan work through emergent issues.

    A further forecasting refinement was attempted by one upstream, componentsupplier. An application was introduced to amalgamate component sales’ forecasts atsystem-level. This provided a more accurate prediction of future sales, since aggregateddata could be compared against external market trends. The impetus behind this projectwas customers’ tendency to over-forecast their requirements to secure supply in thisrapidly growing marketplace, when they knew manufacturing capacity was scarce.

    Supply chain behaviour. Predominantly, traditional inter and intra-organisationalboundaries remain mainly intact. Dyadic buyer-supplier relationships remained themainstay of supply interactions. These were supplemented by a variety of supportroles – whether replenishment or product development-focussed.

    Clear power differentials existed within buying decision-making units, particularlywithin retail organisations. There was substantial evidence of attempts to divorcetraditional elements of buyer-supplier negotiation from “collaborative” activities.Customer-focussed key-account management structures had evolved to “face up” tomajor customers.

    However, such so-called “man-to-man marking” on the customer side, often led togreater intra-organisational complexity. The most complex network of supplyrelationships we studied was found within TelevisionCo. Twenty-six parallel businessline teams were responsible for executing order fulfilment activities for their respectivemarkets. Each of these cross-functional management teams was responsible for

    IJOPM26,7

    766

    the sourcing, capacity planning and operational control of technologically similarsemiconductor products through a common configuration of manufacturing and testoperations. However, managing the intra-relationships between these organisationalunits and an externally-facing sales organisation (to provide a single point of customercontact) raised internal co-ordination challenges.

    Where boundary-spanning specialist “in-plants” where used, these tended to be in“adjoining” organisations (i.e. supplier-customer). There was a wide variety of roles,from project analysts working on information system co-developments and dataanalysts handling promotional evaluations, to goods despatch handlers and specialistmerchandisers. Whilst the employing companies’ declared clear benefits from theseinteractions, the scope of individual roles was often constrained and precarious.

    Promotional activities, increasingly common within UK multiple retailers, createdadditional challenges. These planned events commonly generated an uplift from basedemand of 70-100 per cent. Such demand stimulation required cohesive supply chainplanning if on-shelf availability was to be sustained. However, such was the cut andthrust of commercial competition that promotions were frequently not pre-announcedto branded suppliers for fear of a competitor seizing the initiative. Instead, regionalsafety stocks were held in an attempt to underpin supply continuity.

    Performance measurement. The predominant method of performance measurementwas the use of KPIs that cascaded down from top level business objectives andmeasures, through the organisation into a series of functional measures. Thealternative method found in just two cases was the use of a balanced score card (BSC),which, in the case of 4PL Co Electronics, was sophisticated. The main results inrelation to performance measurement used in SCM are shown in Table V.

    However, even the BSC was cascaded down from business objectives to functionalobjectives. Pharmaco made a conscious effort to try and keep the BSC for differentactivities at the “highest” level possible. For instance, the BSC for distribution was foran entire region and not at individual Regional Distribution Centre (RDC) level.However, the management at the RDC found it to be an inadequate tool for managingthe operation of the RDC and the regional manager in conjunction with the RDCmanagers were in the process of developing a hybrid system that measured both RDCand regional performance. Furthermore, the cascade, whilst seeming to be eminentlysensible in linking metrics, has the pitfall that the sum of the parts does not equate tothe whole. All too often, metrics pursued at a functional level for the benefit offunctional targets, jeopardised the performance of the supply chain as a totality. A goodexample was found in 4PLCo Electronics. The performance measurement systememployed in this supply chain was exemplary in many respects. Metrics were collectedat all stages in the supply chain – daily, weekly, monthly and quarterly – and wereactively reviewed through telephone calls, face-to-face meetings and business reviewmeetings. The format and content was identical across the supply chain and themeasures were used to drive performance improvement and also reward. And withreward, here-in lies the danger. There has been a shift over the last ten years or sotowards metrics that are specific, measurable, achievable, realistic and timely(SMART). This has led managers (particularly middle managers) to expect targets thatare wholly within their span of control. This in turn leads to functionally drivenbehaviour. 4PL Electronics had measures that showed that they consistently achievedtheir 3-day delivery target. However, in reality, for the sample studied, the large

    majority of orders were delivered after the date the customer had originally requested,and on average they were 16 days late. 4PL Electronics were only measured on the partof the supply chain they were in control of and not on what the customer actuallywanted.

    DriversSupply chain management is becoming of increasing strategic importance, and thefieldwork concurred with the literature in identifying globalisation, outsourcing andfragmentation as three major drivers. Evidence to support each of these drivers issummarised in Table VI which shows that, for all cases, evidence of each practice wasfound to a greater or lesser extent.

    However, an additional driver was also uncovered that did not feature sopredominantly in the literature – market polarisation. It could be argued that thispotentially has the most significant effect of all. For Pharmaco, Householdproductscoand TelevisionCo the mid-high markets that they traditionally served havedisappeared and been replaced by a polarised high-end/low-end market profile.ElectronicsCo has such a broad range of products that these naturally fall into polarextremes of the volume: variety continuum yet the supply chain strategy used todeliver these products is not significantly different. This has serious implications forsupply chain management.

    Challenges for SC management and future prospectsThe challenges facing SCM as theory and practice stem from their interplay andmisalignment. The research reported here reveals the substantial gaps between theoryand practice. One central challenge is to the very idea of “managing” the supply chain.Who could and should have this responsibility? Arguably one ideal would be a separatefunction independent of the existing array of functions which are partially but not fullyinvolved. Such a developed function might act as the arbitrator of supply and demand. Anumber of our respondents envisaged that this development could be supported by thematuration of the 4PL concept. Alternatively, some commentators suggest the need toredefine the purchasing role (Mehra and Inman, 2004). A related challenge is to increasethe scope of SCM involvement – the “arc of integration” (Frohlich and Westbrook, 2001).This can only be achieved if the enablers identified above are harnessed more effectively– the greater transparency of information and knowledge, the formation of appropriaterelationships, and the design and use of appropriate measurements.

    So what are the prospects for the future of SCM? There do appear to be some trendsworking in favour of a higher profile and a more developed role for supplymanagement. But we suggest they fall well short of the more full-blown claims of manyof the advocates. We suggest that business models and supply chain practices arechanging in tandem. The most important elements are as follows.

    First, supply chain management can be seen as part of a wider set of trendsinvolving outsourcing, cross-boundary working, new organisational formscharacterised by flattened hierarchies, teams, empowerment and so on rather thanrigid command and control (Ruigrok et al., 1999). These trends present an opportunityfor the development of SCM.

    Second, the trend towards outsourcing and the increasing importance of intangiblesheightens the need for, and the potential of, supply chain management. As contract

    Table VI.Evidence of SC drivers

    manufacturing becomes the norm so the value added role of brand owners who havevalued relations with customers are recognised as having important intangible assetsand skills.

    Third, the trend towards fragmentation and variety in product and service offeringsnecessitates greater thought and skill in managing decoupling points andpostponement of final product composition. Hence, the drivers impelling attention tocrucial issues of alignment are certainly present but this does not mean that the task isgiven to supply chain specialists. This indeed appears to be the source of muchconfusion; simply because there is an apparent need for someone to take a helicopterview of the whole terrain does not mean that this happens in practice. There areundoubtedly issues of professional status and standing intruding here. In most firmsthe supply chain function (in whatever guise it happens to adopt) rarely has thepolitical standing to allow it take command of these critical strategic issues.

    Fourth, globalisation necessitates greater attention to logistics and to othercomponent elements of supply chain management. The same arguments noted abovein relation to fragmentation also recur here. The need is evident; the power to respondis problematic and uncertain. The dispersion of nodes in the supply chain across thecontinents offers new business opportunities to freight handling companies and thirdparty logistics providers. But these interventions cannot be described as constituting“supply chain management” in the holistic senses described in the early part of thispaper. There are wider forces at play – outsourcing, global sourcing, volatile customerdemand, heightened competition, shorter product life cycles, and customisation. Thenthere is the shift to virtuality – leased merge centres, contract manufacturers,innovators who market a concept and have others make it and so on. The pretence that“supply chain management” is a mode of intervention or a self contained disciplinewhich is effectively grappling with these forces is an exaggeration. This is not an arenawhere a neatly managed activity is underway. That said, the change of mindsettriggered by the constellation of forces as described in this paper and elsewhere couldprovide the opportunity for sophisticated and capable managers to engage in practiceswhich approximate to the vision as described above. There could be aprofessionalisation opportunity here, or at least a pathway for further occupationaldevelopment.
