New Fast Track Maintenance process now available

Aug 07, 2017

Beside the current yearly maintenance cycle and the urgent unscheduled maintenance process, a new "fast track maintenance process" has been made available to submitting organisations.

The current ISO 20022 maintenance process is illustrated below. It is usually initiated on a yearly basis, but can also be initiated in a more urgent, unscheduled manner. The yearly process starts in June and usually spans three quarters of a year. When used in an urgent unscheduled manner, the process can be initiated any time and may be reduced up to a quarter.

It is the submitter of the change request who proposes to use the urgent unscheduled process and the Standards Evaluation Group (SEG) in charge of the message definition that authorizes the use of this urgent unscheduled process.


The new fast track maintenance process skips the first two steps of the current maintenance process (that is, the submission of the change request (CR) and its initial review by the SEG in charge of the message definition). The fast track process starts directly with the submission of a Maintenance Change Request (MCR) prepared by the (submitting) organisation that intends to develop the new version of the message definition. The MCR includes all the changes requested by the submitting organisation and the detailed proposed implementation.

The fast track maintenance process can thus be initiated only by the submitting organisation that owns the message definitions (that is, the original submitting organisation) or another organisation that is capable of developing the new message version and has been authorized to do so by the original submitting organisation.


The duration of the fast track maintenance process depends on the diligence of the (submitting) organisation. If this organisation is really in an urgent need for a new message version, it is expected that the MCR will be extremely clear about the implementation of the requested changes, thereby allowing the SEG to take a rapid decision.   Similarly, the development of the new version by the submitting organisation is expected to be fast.

To further speed up the process, the validation of the draft documentation by the SEG will be performed in two stages:

1) approval of the new message description, that is, the Message Definition Report (MDR) - Part 2 and the schemas

2) approval of the auxiliary documentation (MDR Part 1 and 3)

As soon as stage 1) is completed, the new versions will be considered as approved and the MDR Part 2 and schemas will be officially published on the ISO 20022 website by the Registration Authority (RA). This documentation will be complemented by the updated MDR Part 1 and 3 when stage 2) is completed.

The timeframe between the submission of the MCR and the publication of the new schemas is expected not to exceed 2 months.
