What does Service Transition involve in the ITIL framework?

Service Transition in the ITIL framework focuses on the planning and management of service changes while ensuring that the services are delivered effectively and efficiently. The correct choice highlights the key components of Service Transition, which include building, testing, and preparing services for live operations. This phase is critical because it ensures that new and changed services are designed properly, transitioned smoothly, and are ready for deployment in a live environment.

Service Transition involves various activities such as preparing the environment and supporting documentation, ensuring proper testing and validation of the services, and ultimately ensuring that everything is aligned with service management processes before the services go live. This ensures minimal disruption to existing services and helps in delivering high-quality services that meet customer needs.

Other options, while they refer to important aspects of service management, do not accurately depict the essence of Service Transition in ITIL. Delivering ongoing support indicates the Operations phase rather than the transition process, monitoring performance pertains to the continual improvement of services and service management, and creating new marketing strategies is unrelated to the ITIL framework's service management practices.
