The Information Technology Infrastructure Library (ITIL®) is a framework with the goal of closing the gap between IT departments and the needs of a business. The application of the developed guidelines within the framework of ITIL® allows IT departments to improve their overall efficiency; from the way IT infrastructure is created and managed to how individual service interactions within the business are conducted.
Through the use of Key Performance Indicators (KPIs), ITIL® measures the effectiveness of an IT organization by analyzing data related to performance, issues, process improvement, and progress. Given its framework structure, one of the key strengths of ITIL® is its ability to be adapted and modified to fit the unique structure and needs of an organization. By not prescribing a specific set of rules, the dynamic nature of ITIL® affords the ability to be scalable and flexible within an organization.
