ITIL: Overview and Benefits
ITIL advocates that IT services must be aligned to the needs of the business and underpin the core business processes. It provides guidance to organisations on how to use IT as a tool to facilitate business change, transformation and growth.
The ITIL best practices are currently detailed within five core publications which provide a systematic and professional approach to the management of IT services, enabling organisations to deliver appropriate services and continually ensure they are meeting business goals and delivering benefits.

The five core guides map the entire ITIL Service Lifecycle, beginning with the identification of customer needs and drivers of IT requirements, through to the design and implementation of the service into operation and finally, on to the monitoring and improvement phase of the service.

Adopting ITIL can offer users a huge range of benefits that include:

• improved IT services
• reduced costs
• improved customer satisfaction through a more professional approach to service delivery
• improved productivity
• improved use of skills and experience
• improved delivery of third party services.
