Clearly, given the fact that change is a natural part of the process and that change will come from both external and internal sources, we need a process for managing change. Such a process puts the team in control so that it can effectively discover change, perform impact analysis, and incorporate those changes that are deemed both necessary and acceptable into the system in a systematic manner. Building on Weinberg's recommendations, a process for more effectively managing change must include the following steps.
1. | Recognize that change is inevitable, and plan for it. |
2. | Baseline the requirements. |
3. | Establish a single channel to control change. |
4. | Use a change control system to capture changes. |
5. | Manage change hierarchically. |
