Understanding Service Transition

Question Mark Made From Colorful CubesITIL® has grown to become the most widely accepted approach to IT Service Management.  The most recent version of ITIL, ITIL V3, takes a Lifecycle approach.  Service Transition is one of the five stages in the ITIL Service Lifecycle, along with Service Strategy, Service Design, Service Operation, and Continual Service Improvement.

Service Transition focuses on delivering new or modified services from the test environment to the live production environment in a relevant and cost-effective manner without causing interruptions or disruptions to other services or processes. The goal of Service Transition is to help organizations plan and manage Changes as well as test and deploy Releases. For effective Service Transition, an organization must recognize the need and importance of a service and the benefits it can bring to the organization.

Service Transition focuses on:

  • Managing the complexity of Changes to services and Service Management processes
  • Introducing services
  • Transferring services
  • Decommissioning and discontinuing services

Benefits of Service Transition include:

  • Estimating the costs, timing, resources, and risks associated with a service
  • Deploying Changes more successfully
  • Easier to follow processes and procedures
  • Diminishing delays and downtimes due to services and Changes being analyzed in a test environment
  • Improved confidence that the new or changed service will meet needs and expectations without affecting other services or stakeholders
  • Verifying that new or changed services are maintainable and cost-effective

Key Service Transition processes include Change Management, Service Asset and Configuration Management, Release and Deployment Management, and Knowledge Management.

By implementing the ITIL framework within an organization, an organization will be able to deliver high-quality services to users and customers in an efficient manner.
