Overview of the Service Lifecycle

ITIL V3 approaches service management from the lifecycle aspect of a service. The service lifecycle is an organizational model that provides insight into:

  • The way service management is structured.
  • The way the various lifecycle components are linked to each other.
  • The impact that changes in one component will have on other components and on the entire lifecycle system.

Thus, ITIL V3 focuses on the service lifecycle, and the way service management components are linked. Processes and functions are also discussed in the lifecycle phases.

The service lifecycle consists of five phases. Each volume of the core ITIL books describes one of these phases. The related processes and functions are described in detail in the phase where they have the strongest association. The five phases are:

    • Financial management
    • Service portfolio management
    • Demand management
    • Business Relationship Management
    • Strategy Management
  2. Service Design – The phase of designing and developing appropriate IT services, including architecture, processes, policy and documents; the design goal is to meet the current and future business requirements. Processes and functions:

The Service Design, Service Transition and Service Operation phases are guided by this Strategy; their continual theme is adjustment and change. The Continual Service Improvement phase stands for learning and improving, and embraces all other lifecycle phases. This phase initiates improvement programs and projects, and prioritizes them based on the strategic objectives of the organization.
