You need to recommend a software development methodology for an upcoming project. From the methodologies presented in this chapter, choose a methodology for each of the following projects. Briefly provide the rationale for each choice.

a. A system for monitoring electrical surges in an electrical power grid.

The requirements for the system are well understood. Users will be required to use the system.

b. A contact management system. The system's potential users are unsure of exactly what they want the system to do. Use of the system will be voluntary.

c. A relatively small order-tracking system. The objectives of the system are well known, and potential users very much want such a system.
