ITIL: Information Technology Infrastructure Library.
ITIL is an integrated set of best-practice lifecycle recommendations with common definitions and terminology. It is actually divided into a series of five documents/books, which are known commonly as 'sets' or 'volumes'. The volumes themselves describe what are often termed 'disciplines', covering individual subjects and approaches.
Conceptually, the driving volume is 'Service Strategy', which offers a view of ITIL that aligns business and IT so that each brings out the best in the other. The remaining four volumes are Service Design, Service Transition, Service Operation and Continual Service Improvement. An established and well defined certification scheme is also in place to support ITIL. This comprises three disctinct levels: Foundation, Practitioner and Manager. This is discussed in a separate section of this portal.ITIL is a series of documents, originally created by the Office of Government Commerce, a governmental department in United Kingdom. These are used to help implement an efficient framework for IT Service Management (ITSM).
This 'ITIL framework' essentially defines how to organize the system and network management departments within individual organizations. The concepts within ITIL support IT service providers in the planning of consistent, documented, and repeatable processes that improve service delivery to the business.
ITIL addresses the organizational structure and skill requirements for an IT organization by presenting a comprehensive set of management procedures with which an organization can manage its IT operations.The ITIL Certification structure is broadly as follows:

The Foundation Certificate enables people to understand the terminology used within ITIL. It focuses on foundation knowledge with regard to the ITIL Service Support and Service Delivery sets as well as generic ITIL philosophy and background. It is a prerequisite for the Practitioner's and Manager's Certificates in IT Service Management.
The Practitioner Certificate focuses upon the understanding and application of the specific processes within the IT Service Management discipline.
The Manager's Certificate is aimed at experienced professionals, who will be involved in managing service management functions.
