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”.
