The Information Technology Infrastructure Library methodology involves five core publications that enable organizations to deliver information technology services and meet business goals. The methodology defines the processes of problem, incident, change, configuration and release management. These publications map the ITIL service life cycle, which guides organizations from the initial stage of identifying customer needs to designing and implementing IT services. The ITIL service life cycle also guides organizations through monitoring and continual improvement phases.

The Information Technology Infrastructure Library methodology does not compel organizations to implement all the specifications outlined in its framework. Small and medium-sized businesses can adopt the most important features to achieve cost savings.
