Change Management
Service description
The Change Management aims to control the lifecycle of all Changes. The primary objective of this process is to enable beneficial Changes to be made, with minimum disruption to customer services.
• The structure of the Change Management process highlights that significant changes require authorization at different points in their lifecycle.
• Change Management embeds dedicated sub-processes to assess Change Proposals and to implement minor Changes.
• On the other hand, Change Management submits major Changes to the Change Evaluation process for a formal assessment.
• Change Scheduling ensures that the detailed planning of a Change and the corresponding Release is performed by Release Management.
• Change Management embeds also Change Models, putting more emphasis on defining different types of Changes and how they are to be handled. Furthermore, Change Models are given a more prominent role in Change Management, being used not only for Standard Changes (low-risk Changes on an operational level), but also for recurring significant Changes.
