Continuous Service Improvement: This phase defines new requirements for the preceding phases of ITIL based on operational feedback and service levels. It helps to ensure that policies and procedures are followed, that service level agreements are met and that operational lessons learned are incorporated into existing and future service refinements.
This official ITIL Foundation certification course provides you with a general overview of the IT Service Management Lifecycle which is outlined in ITIL’s five core books – Service Strategy, Service Design, Service Transition, Service Operation and Continual Service Improvement.

Often confused with the role of incident management from service support, operations has a more technical bias and is concerned not solely with incidents reported by users, but with events generated by or recorded by the infrastructure.
