Change Management

A critical component of project monitoring and control is change management. As business requirements and operating environments change all the time, the project manager has to manage change throughout the software development cycle from acquisition, supply, development, operation, and then maintenance. The guiding principles, techniques, and tools for change management are discussed in this chapter.


Nothing is rarer in information systems development than an application without changes. Users forget requirements and remember them late in the design. The business changes. Bugs get fixed and require documentation. Change occurs in all phases and all levels of application development. Procedures to manage change, therefore, are necessary to maintain sanity and order on the project team. 

The three major types of change in an application's life cycle-requirements, software, and documentation-are discussed in this chapter. For each, the importance of the change management techniques is discussed. Then, for each, techniques for managing changes are developed. At the end of the chapter, automated tools are identified for collaborative work, documentation, reverse engineering, and code management. First, we discuss the importance of designing for maintenance, regardless of the environment, architecture, or item being developed.
