ISO 20000 IT Service Management Systems
ISO 20000-1 is the international standard for quality management specifically focused around IT service management. ISO 20000:2011 (the latest version of ISO 20000-1) provides a set of standardised requirements for an IT service management system (SMS). Given how vital IT is to organisations it is essentially that both your internal and external IT services are aligned with the needs of your businesses and customers.
An increasing number of organisations are implementing an IT Service Management System (ITSMS), based around ISO 20000 as a solution to this business requirement. By certifying to the IT standard companies are able to independently demonstrate to their customers that they are meeting (and sometimes exceeding) industry best practice.
