Why ITIL

ITIL (the IT Infrastructure Library) is essentially a series of documents that are used to aid the implementation of a framework for IT Service Management. While the Service Management sets (Service Support and Service Delivery) are by far the most widely used, circulated and understood of ITIL publications, ITIL provides a more comprehensive set of practices as a whole. IT Service Management as a concept is related but not equivalent to ITIL which, in Version 2, contained a subsection specifically entitled IT Service Management (ITSM).

It would be wrong to assume that every aspect of PRINCE2 will be applicable to every project. A means for capturing and assessing project issues is suggested together with the way in which corrective action should be taken. Why ITIL Capacity Management supports the optimum and cost effective provision of IT services by helping organizations match their IT resources to the business demands.

Analogous to debates in software engineering between agile and prescriptive methods, there is debate between lightweight versus heavyweight approaches to IT service management. The ITSC manager will ensure that the ITSCM process is implemented and maintained in accordance with the organization's requirements and business continuity management process.

After implementation has been completed, the process needs to be maintained as part of business as usual.
