Revised version

ISO/IEC 20000-1:2018 was released on 30 September 2018. There are several significant changes in the new edition, but overall, the scope of the changes can be considered moderate. The key change is the adoption of a common framework for ISO management system standards with a Common High-Level Structure (HLS), common text and definitions. Hence, the document has been completely restructured compared to the 2011 edition. Some other important changes in IT service management should also be noted.


How to prepare for the implementation of the new version?

We recommend that you start preparing for the transition as early as possible and plan properly to incorporate the necessary changes into your management system.


Recommended transition steps:

Familiarize yourself with the content and requirements of the new standard. If you are a current user of the 2011 standard, you should focus on changes in requirements.

Make sure the relevant staff in your organization are trained and understand the requirements and key changes.

Identify gaps that need to be addressed to meet new requirements and establish an implementation plan.

Implement activities and update your management system to meet the new requirements.
