What is the purpose of service transition?

The purpose of service transition is to ensure that changes made to services and service management processes deliver the expected business value while minimizing risk and disruption to existing services. This phase of the service lifecycle is focused on the planning and management of the transition of new or changed services into the operational environment. It involves managing all aspects of the transition process, including the coordination of people, processes, and technology to achieve successful implementation.

By emphasizing the assurance that changes will meet their intended aims, service transition helps organizations align services with the needs of the business and allows for the realization of benefits from those changes. This leads to improved service delivery, better customer satisfaction, and a more adaptive organization.

The other options do not fully capture the core objectives of service transition. While enhancing existing services, providing detailed knowledge of IT services, and reviewing past service incidents may be important in their own right, they do not directly relate to the primary aim of ensuring that changes facilitate expected business value.
