What is the primary responsibility of Service Transition?

The primary responsibility of Service Transition is to ensure that new or changed services are delivered to the production environment successfully. This phase of the ITIL lifecycle focuses on planning and managing the deployment of these services, which includes both the technical aspects of the transition and the coordination of activities with other stakeholders.

Service Transition is crucial because it aims to minimize risks and ensure that services meet the requirements set forth in the service design phase. This process involves several activities, such as managing service asset and configuration, validating and testing the service, and ensuring that all stakeholders are informed and prepared for the changes. By focusing on successful delivery and minimizing disruptions, Service Transition helps organizations effectively integrate new or modified services into their existing operations.

In contrast, the other options refer to activities and processes that occur in different stages of the ITIL lifecycle. Monitoring ongoing service performance is usually part of the Service Operation phase, gathering feedback from users is a continuous activity relevant across all lifecycle stages, and conducting follow-up reviews of service quality is often associated with the continual service improvement phase. Thus, the emphasis in Service Transition is distinctly on the successful deployment of new or changed services into the production environment.
