Unfortunately we all live in a world of constraints. There arent many people who can make an expensive purchase without foregoing something else or take on a new project without taking time away from an existing one. Usually these are fixed-sum constraints; we only have so much discretionary income per month and so many hours in a day.
Sometimes the options or the things from which were choosing are related. For example you cant get a new car with premium speakers unless you also order the deluxe entertainment package or get a keyless ignition without keyless entry.
General Note: To earn maximum credit you should post to the module discussion board in the first week of each module. Theres no reason not to because the discussions are non-technical. Each topic is intended to get us thinking about the type of management problem discussed in each module. The topics dont require any research or any prior knowledge of management; theyre based upon our own mundane experiences.
