The requirement development process for a system starts when a user need is first mentioned. Requirement analysis starts when someone tries to interpret this attempted communication. After that the process that leads from user needs to specific performance parameters of an actual system is described by some as “chaotic.” Current methods isolate several user needs at a time, then a few point solutions are studied to determine which one is most cost effective. This paper addresses how this process should be performed for the class of problems where there are many user needs, many possible solutions (i.e. systems), and each solution has some potential for satisfying multiple user needs. The objective is to determine what combination of performance characteristics for each potential system provides the greatest marginal contribution to the entire set of user needs.
