Service Transition builds and deploys new or modified services.

The ITIL service lifecycle stage of Service Transition (see fig. 1) includes the following main processes:

Process Objective: To assess major Changes, like the introduction of a new service or a substantial change to an existing service, before those Changes are allowed to proceed to the next phase in their lifecycle.

Process Objective: To plan and coordinate the resources to deploy a major Release within the predicted cost, time and quality estimates.

Process Objective: To make available applications and systems which provide the required functionality for IT services. This process includes the development and maintenance of custom applications as well as the customization of products from software vendors.

Process Objective: To plan, schedule and control the movement of releases to test and live environments. The primary goal of Release Management is to ensure that the integrity of the live environment is protected and that the correct components are released.
