Which process involves managing all changes to IT services?

Change Management is the process responsible for managing all changes to IT services in a controlled manner, ensuring that standard procedures are followed to minimize the impact of changes on service quality and availability. This process includes assessing, approving, implementing, and reviewing changes to ensure they align with business objectives and do not disrupt existing services or operations.

The importance of Change Management lies in its ability to systematically handle modifications, whether they are upgrades, fixes, or new functionalities. By doing so, it helps in maintaining service continuity while facilitating improvements to the IT infrastructure. The effective implementation of Change Management reduces the risk of errors and service interruptions that can arise from uncoordinated changes.

Other processes mentioned have distinct focuses: Release Management deals specifically with the deployment of new or changed services into the live environment, ensuring they are built, tested, and delivered correctly. Incident Management is focused on restoring normal service operation as quickly as possible after an incident occurs, while Configuration Management maintains the integrity of service assets and their configurations but does not directly control changes to those assets. Thus, while all these processes are vital within ITIL, Change Management's primary goal is to manage changes to IT services comprehensively.
