ISO/IEC 20000 is an international standard for IT service management that specifies requirements for establishing, implementing, maintaining and improving an IT service management system. It aims to ensure consistent service delivery and provide customers with proof of effective IT service management. While based on ITIL best practices, ISO/IEC 20000 differs in that it focuses on certifying an organization's quality management system and processes rather than individual qualifications. Organizations can become certified through an independent audit to demonstrate their compliance with over 200 requirements specified in the standard.
