Change Management is the process of recording, evaluating, approving, planning, and overseeing the implementation of a change in a controlled and efficient manner. A change is an addition, modification to, or removal of, applications, infrastructure, or technical client services, service components, or related configuration items and their associated documentation. In Service Management, the goal of Change Management is to protect the live environment. The authority for approving changes can be assigned to the Change Manager, the CAB or ECAB, and other identified parties.
