ISO/IEC 20000 is an international standard for IT service management that describes processes for effective delivery of IT services. It is aligned with ITIL best practices and consists of two parts - ISO/IEC 20000-1 defines requirements for delivering managed services, including management systems, service delivery and control processes. ISO/IEC 20000-2 describes best practices to help organizations prepare for audits and improve service management. Adopting ISO/IEC 20000 can help IT organizations better meet customer needs, implement industry best practices, and improve quality, efficiency, and transparency of IT services.
