ISO/IEC 20000 is an international standard for IT service management aimed at integrating processes to meet business and customer requirements. The standard is structured into three parts: Part 1 sets the requirements for effective service management, Part 2 describes best practices that support these requirements, and Part 3 offers guidance on conformance. Certification may provide competitive advantages, client compliance, and aid in continual improvement efforts, making it beneficial for organizations seeking to enhance their IT service management practices.
