ITIL (Information technology infrastructure library) Definition

ITIL Definition
Information technology infrastructure library

ITIL is basically for them who deliver IT services-----M. imp. line

ITIL in short is " How IT can provide better value to business"

HOW????????

ITIL describes life cycle, processes, procedures, tasks, functions and checklist that are not organization specific-  i.e. 

[Good and bad practices material gathered and documented (because it is a library) are based on years of experiences by the IT practitioners designed for any information technology service delivery model.]

It is used by organisations to establish integration with company vision and strategy (by continually improving as well as changing services provided by company) focused on delivering services that are of value and importance while maintaining its costs and risks.

It allows the IT organisation to establish a baseline from which it can plan, implement and measure its services to its customers and ensure continual improvements.

It also reduces costs by leveraging efficiency to improve productivity on IT staff & resources.

Above definition is bookish but what i personally think is that ITIL is a philosophy about IT service delivery.

For eg:-

Think like that You are a IT service provider and to keep customers satisfied with the services, I choose to build a proven service model which includes many idle recommendations.

And what is idle is the way of conducting business...........
