Which process would maintain policies, standards and models for service transition activities and processes?

Change management focuses on controlling the lifecycle of individual changes through evaluation and authorization, not on setting the overarching policies and models for the broader transition stage.

Capacity management is concerned with ensuring that IT capacity meets current and future business demands in a cost-effective manner, and has no ownership of transition policies or standards.

Service transition planning and support owns the frameworks that guide how transitions are conducted, including reusable models, standards for documentation, and policies that all other service transition processes must follow. This governance role ensures consistency and quality across the entire transition lifecycle.

Release management plans and controls the build, test, and deployment of releases into live environments, but does not own the governance policies and standards framework for service transition.
