In this paper Trevor explores the principles of Services Transition and how it is used to build and deploy IT services.

The main objective of Service Transition is to build and deploy IT services, ensuring that the changes to IT Services and Service Management processes are carried out in a coordinated way.

In the previous paper “Enterprise Architecture and ITIL®: Implementing Service Design” Trevor Lea-Cox looked at some important concepts in Service Design (SD). Now, in this latest paper, Trevor explores the principles of Services Transition by:

• Reviewing some important principles used in ITIL for managing the transition of IT Services into Service Operation.

• Summarizing the main ITIL processes for managing Service Transition.

• Showing how these principles would be applied to the “EA Publishing Service”.
