The IT Infrastructure Library (ITIL) is a set of best practices for IT service management. Developed by the UK government in the 1980s, ITIL has since become the most widely accepted framework for IT service management. It provides a comprehensive approach to managing IT services, including processes, procedures, and policies.
The ITIL Framework
The ITIL framework is made up of five core publications, each covering a different aspect of IT service management. These publications include:
- Service Strategy
- Service Design
- Service Transition
- Service Operation
- Continual Service Improvement
Each of these publications contains a set of best practices, processes, and procedures for managing IT services.
The ITIL framework includes a number of processes that are used to manage IT services. Some of the most important ITIL processes include:
- Incident Management – This process deals with the management of incidents, which are unplanned interruptions to IT services. The goal of incident management is to restore normal service operation as quickly as possible.
- Problem Management – This process deals with the management of problems, which are the underlying causes of incidents. The goal of problem management is to prevent incidents from happening in the first place.
- Change Management – This process deals with the management of changes to IT services. The goal of change management is to ensure that changes are made in a controlled and predictable manner.
- Configuration Management – This process deals with the management of IT assets, such as hardware and software. The goal of configuration management is to ensure that IT assets are properly tracked and updated.
- Release Management – This process deals with the management of software releases. The goal of release management is to ensure that software releases are properly tested, planned, and deployed.
- Service Level Management – This process deals with the management of service levels. The goal of service level management is to ensure that IT services meet the needs of the business.
There are several ITIL certification levels available, including ITIL Foundation, ITIL Practitioner, ITIL Intermediate, and ITIL Expert. The ITIL Foundation certification is the entry-level certification and is a prerequisite for the other certifications. The ITIL Practitioner certification focuses on the practical application of ITIL, while the ITIL Intermediate and ITIL Expert certifications focus on specific ITIL processes and best practices.
