ITIL® – the IT Infrastructure Library® for IT Service Management (ITSM)

What is ITIL?

The Information Technology Infrastructure Library (ITIL®) IT service management (ITSM) and is usually used in preperation for ISO/IEC 20000 certification. The framework is based around a five-phase service lifecycle: service strategy, service design, service transition, service operation and continual service improvement.

  1. Service strategy - involves understanding customers and how to develop and successfully execute IT services to meet their needs.
  2. Service design - ensures that the service is designed efficiently and cost-effectively.
  3. Service transition - sees the design built and tested.
  4. Service operation - delivers and manages the service.
  5. Continual service improvement - provides a mechanism for improving the service and the technology and processes used in its management.

If you are new to ITIL, we recommend the following books:

ITIL, ITSM and ISO 20000

Although they have much in common, ITIL and ISO/IEC 20000 serve different purposes.

ISO 20000 is the standard for service management processes. Organisations can attain independently audited certification to the Standard to demonstrate that they are following ITSM best practice.

ITIL provides advice on ITSM best practice. It includes options that may be adopted and adapted by organisations according to business needs, local circumstances and the maturity of the service provider.
