The revision of ISO/IEC 20000-1 is expected to publish ahead of schedule - July or August 2018.

ISO/IEC 20000-1 revision schedule

The revision of ISO/IEC 20000-1 was expected to publish late October/early November. However, ISO are working faster than anticipated and the revision is likely to publish in July or August 2018.

The final draft internal standard (FDIS) has been released and is now with national bodies for an 8-week ballot which will complete at the end of June.

Now the FDIS is released, it will be available to purchase to get a view of the final revised standard. However, please be aware that the FDIS may change before publication of the revised standard although any changes at this stage should only be editorial.

After the ballot and assuming it will pass (the DIS ballot passed with 100% approval so no issues anticipated), then there will be a time period to deal with editorial comments and for ISO to finalise the document.

Further news

Part 10, Concepts and Vocabulary, is currently out for DIS ballot and is likely to move straight to publication with only very minor updates after DIS. We are trying to ensure that parts 1 and 10 are published together.

Part 2 and part 3 revisions continue with a plan to publish these shortly after part 1. Likely publication will be in 2019.

Part 4 – process reference model: It has been agreed that this will no longer be part of the 20000 series. The process reference model is currently used by a process assessment model called 15504-8. When these are updated for the revised 20000-1, they will be done within a different ISO committee that specialise in these models and will become part of the 33000 series. Expected publication is 2019.

ISO/IEC 90006 – mapping to ISO 9001:2008: This document will be withdrawn since it will apply to an out of date 9001 and an out of date 20000-1. Discussions are ongoing about the usage of this document and a possible change to make it into an ISO20000 part about integration between 20000-1 and 9001.

ISO/IEC 27013 – integration of ISO/IEC 27001 and ISO/IEC 20000-1: The ISO committee that owns the 27000 series (SC27) will start the update in 2019.

Discussions are ongoing about producing an ISO guide about the use of ISO/IEC 20000-1 with new technologies and methods e.g. SIAM, Devops, Cloud, Internet of Things.

Training transition

Many training organizations are already working to produce transition courses and to update their normal courses for the revised edition.


If you are already certified or starting to implement ISO20000 part 1, do not worry. It is likely that there will be a 2-year transition period following the revision of part 1. Nothing you are doing now for the current ISO/IEC 20000-1 will be wasted so keep going and then transition in a managed way.
