Change Management is a field in the IT Service Management (ITSM). Change Management ensures the use of standard methods and procedures to efficiently handle changes in IT infrastructure and decrease the number of any related occurrence to IT services.
The changes in IT infrastructure may stem from responses to problems or external requirements such as legislative change, business initiatives, and program-project or service-improvement initiatives.
Change Management comprises the following procedures:
- rising and recording of changes;
- benefit, cost, impact, and risk assessment of projected changes;
- development of business validation and acquisition of approval;
- management and coordination of change implementation;
- monitoring and reporting change implementation; and
- review and closure of change requests.
Change Management is the management of change processes involving communications software and equipment, hardware, system software, documentation, procedures related to the operation, support, and maintenance of existing systems.
ITSM Change Management does not usually oversee changes within deployment or the delegation of development projects decreed by project management methodology. However, the project manager may use Change Management to supervise items in production or the requisite criteria for testing, production, and subsequent release methods.
Any projected change to the Change Management process must be approved before being implemented. Change Management facilitates the process under the examination of the Change Advisory Board (CAB). The CAB is mostly composed of individuals under other functions in the organization.
The Change Advisory Board filters changes and manages changes and change process. It also chairs the CAB and CAB/Emergency committee. It requests for Change (RFCs) review and conclusion. It also manages reporting and the provision of management information.
