Information Technology Infrastructure Library (ITIL) is an IT service management framework. ITIL focuses on the key principles for any business: how to enhance IT values, services, increase efficiency and improve customer satisfaction.
ITIL implementations have been designed to help companies determine the need of improvement in any potential areas.
Note: ITIL is not a tool. It is a set of business implementations applicable to IT services management.
The objective behind ITIL is to ensure that an IT professional is aware of the best possible solutions in any service management situation. ITIL helps companies by reducing costs and improving IT services. A number of major IT companies around the world consider ITIL certification as a crucial requirement in IT service management.
