Chapter Review

Change management is an essential management tool and control mechanism. The key concept of segregation of duties ensures that no single individual or organization possesses too much control in a process. Therefore, it helps prevent errors and fraudulent or malicious acts. The elements of change management (configuration identification, configuration control, configuration status accounting, and configuration auditing), coupled with a defined process and a change control board, will provide management with proper oversight of the software lifecycle. Once such a process and management oversight exists, the company will be able to use CMMI-DEV to move from ad hoc activities to a disciplined software management process.
