Service Transition Overview

Service Transition is the phase in the Service Lifecycle in which services that are needed by the business are put into operational use. The Service Transition publication provides guidelines on how the requirements defined in the Service Strategy phase and coded into the Service Design Packages can be transitioned effectively into Service Operation.  In addition, Service Transition explores how errors, disruptions, and risks of failure can be reduced.

In any business when there are changes required in a service or in the delivery of a service, there will have to be changes in the Service Transition stage to have the desired modification reflected in the actual service.  The Service Transition stage ensures the smooth functioning in the delivery of IT services by developing and improving the necessary skills for the transition of new or modified services. It builds and deploys Changes to services and Service Management processes in a coordinated way. In addition, Service Transition ensures that other processes or services are not interrupted or disturbed when an organization is going through a Change.

The following processes are part of the Service Transition phase:

  • Release and Deployment Management – plans, builds, tests and delivers the capabilities of the services in accordance with the Service Design specifications.
  • Service Asset and Configuration Management – allows IT management to execute control of Service Assets and Configuration Items by keeping up-to-date and verified information, which is stored in the Configuration Management System.
  • Change Management – allows Changes to be made across the organization with minimum disruption to IT services by balancing the need for flexibility with the need for stability.
  • Transition Planning and Support – plans and coordinates resources to make sure that the requirements detailed in the Service Design phase are realized.  This process also identifies, manages, and limits risks that could interrupt or disrupt the service.
  • Service Validation and Testing – is responsible for ensuring that the new or changed service not only provides value to the business and customers but also meets all of the customer specifications and is fit for use and fit for purpose.
  • Knowledge Management – makes sure that the proper person has the correct information at the right time to make an informed decision.
