ISO/IEC 20000 is an international IT standard that allows companies to demonstrate excellence and prove best practice in IT management. The standard ensures companies can achieve evidence-based benchmarks to continuously improve their delivery of IT services. ISO/IEC 20000 was released in 2005 based on the IT infrastructure library (ITIL®) best practice framework, and updated in 2011.

The adoption of ISO/IEC 20000 has grown quite rapidly in the international arena of IT service providers and it has become a competitive differentiator for delivery of IT services.
