ITIL 4 is the latest version of the information technology infrastructure library, released in 2019—this version is, so far, the most agile, customizable, and flexible. ITIL 4 offers a systematic approach to ITSM with more stable IT environments, reduced expenses, better awareness of risk, and enhanced customer support. The methodologies focus more on automated processes, the integration and expansion of service management beyond IT, and the improvement of collaboration and communication across the entire organization.
