3. CHANGE MANAGEMENT (CHAPTER 4) Change management is the process that approves and schedules the change in order to ensure the correct level of notification and minimal user impact. These are the key steps for change management: 1. Assign a change controller who can run change management review meetings, receive and review change requests, manage change process improvements, and act as liaison for user groups. 2. Hold periodic change review meetings to be attended by system administration, application development, network operations, and facilities groups, as well as general users. 3. Document change input requirements, that includes change owner, business impact, risk level, reason for change, success factors, back out plan, and testing requirements.
