ITIL is the acronym for Information Technology Infrastructure Library, which is a framework that encompasses a set of best practices for delivering IT services. ITIL provides a standardized approach to build and manage stable IT Infrastructure that offers lesser risks, higher efficiency, and scalability for growth.
As one of the most popular and widely accepted framework for IT service management today, organizations use the best practices laid down by ITIL for increasing operational efficiency and IT service improvement. The nucleus of ITIL is structured around a Service Lifecycle which consists of the five phases below:

To extract maximum benefit from ITIL, an organization need not employ all the practices. The trick to success is to use the ones that add value and align to strategic objectives. For example, many organizations tried to use virtualization and network transformation that needs ITIL Framework, but lack of expertise has resulted in overkill at an extensive cost.
