What is an ITIL V3 Lifecycle?

The ITIL® V3 Lifecycle is a model that is intended to illustrate relationships and dependencies between various independent lifecycles that comprise a mature, enterprise IT Service Management program.

To be clear, this model encompasses many IT Management conceptualization, planning, development, deployment and support paradigms and is not strictly confined to a Service Lifecycle.

In other words, the full ITIL® V3 Lifecycle supports all aspects of an enterprise IT Service Management program – not just the operational management of services.
