The Change Management process depends on the accuracy of the configuration data to ensure the full impact of making Changes is known. There is therefore a very close relationship between Configuration Management, Release Management and Change Management.
Details of the Change process are documented in SLAs to ensure that Users know the procedure for requesting Changes and the projected target times for, and impact of the implementation of Changes.
Details of Changes need to be made known to the Service Desk. Even with comprehensive testing there is an increased likelihood of difficulties occurring following Change implementation either because the Change is not working as required or expected, or because of queries on the change in functionality.
The Change Advisory Board (CAB) is a group of people who can give expert advice to the Change Management team on the implementation of Changes. This board is likely to be made up of representatives from all areas within IT and representatives from business units.
