Service Transition

4. Service Transition Processes

^4.1PLAN/SUPPORT

^4.2CHANGE

This chapter sets out the processes and activities on which effective Service Transition depends. These comprise both lifecycle processes and those almost wholly contained within Service Transition. Each is described in detail, setting out the key elements of that process or activity.

The processes and activities and their relationships are se' out in Figure 2.3, and the topics specifically addressed in this chapter are:

Transition Planning and Support
Change Management
Service Asset and Configuration Management
Release and Deployment Management
Service Validation and Testing
Evaluation
Knowledge Management.

Some of these processes are used throughout the service lifecycle, but are addressed in this publication since they are central to effective Service Transition.

The other processes and activities are mostly contained within the Service Transition phase of the lifecycle, but also are made use of in other phases, e.g. evaluation of design, and performance testing within operations. The scope, goals, purpose and vision of Service Transition as a whole are set out in section 2.4.
