The service transition planning and support process ensures the orderly transition of a new or modified service into production, together with the necessary adaptations to the service management processes.

The service transition planning and support process must incorporate the service design and operational requirements within the transition planning. This essentially involves the management and control of the transition plan, specifically the coordination of the following aspects:

• Integration and alignment of the transition planning with the customer, service and contract portfolio.
• Coordination of the progress of the transition with modifications, pending items, risks and variances.
• Quality review of all service transition, release and deployment plans.
• Implementation of the transition process, support systems and tools.
• Monitoring and improvement of the service transition performance.
