Which process has the following objective 'Establish new or changed services into supported environments within the predicted cost, time and resource estimates'?

Service Strategy defines the overall direction and goals for IT services but does not manage the execution of transitioning services into supported environments.

Service Transition Planning and Support is the ITIL process specifically responsible for coordinating resources across all service transition activities to ensure new or changed services are delivered within agreed cost, time, and resource constraints. It provides oversight and governance for the entire transition lifecycle, from planning through deployment into the supported environment. This distinguishes it from other processes that may contribute to transition but do not own this top-level objective.

Service Level Management focuses on negotiating, agreeing, and monitoring service level agreements with customers, not on coordinating transition activities.

Change Management controls the lifecycle of individual changes to minimize disruption, but it does not own the broader objective of establishing services within predicted cost, time, and resource estimates.
