ISO 20000 is an IT service management standard for organizations, aimed at providing a model for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving an IT service management system (ITSM). Establishing an IT Service Management System (ITSM) has become an essential mechanism for various organizations, especially financial institutions, telecommunications, high-tech industries, and others, to manage operational risks. ISO 20000 provides IT managers with a reference framework for managing IT services, and a comprehensive level of IT management can also be demonstrated through certification.
