ITIL - Transition

Service Transition: delivery of services required by a business into live/operational use, and often encompasses the project side of IT rather than business as usual (BAU).  

Service Transition Processes

  1. Transition planning and support - coordinate the resources to deploy a major Release within the predicted cost, time and quality estimates

  2. Change management - ensure that standardized methods and procedures are used for efficient handling of all changes.

    • Aims of Change Management:
      • Minimal disruption of services
      • Reduction in back-out activities
      • Economic use of resources involved in the change
    • Types of Change Management:
      • Standard Change
      • Normal Change
      • Urgent/Emergency Change
  3. Service asset and configuration management - maintain information about Configuration Items required to deliver an IT service, including their relationships

    • Key Processes:
      • Identification
      • Planning
      • Change control
      • Change management
      • Maintenance
  4. Release and deployment management - plan, schedule and control the movement of releases to test and live environments. The primary goal of Release Management is to ensure that the integrity of the live environment is protected and that the correct components are released.

    • Goals:
      • Planning the rollout of software
      • Designing and implementing procedures for the distribution and installation of changes to IT systems
      • Effectively communicating and managing expectations of the customer during the planning and rollout of new releases
      • Controlling the distribution and installation of changes to IT systems
  5. Service validation and testing - ensures deployed releases and resulting services meet customer expectations, and to verify that IT operations is able to support the new service.

  6. Change evaluation - assess major Changes, like the introduction of a new service or a substantial change to an existing service, before those Changes are allowed to proceed to the next phase in their life cycle.

  7. Knowledge management - gather, analyze, store and share knowledge and information within an organization. The primary purpose of Knowledge Management is to improve efficiency by reducing the need to rediscover knowledge.
