BPM change management process
The ISO systematic and publicly transparent BPM Change Management process ensures the consideration of all relevant information when modifying BPMs. The change management process uses a system available through the ISO public website that provides a way to propose BPM changes, comment on open change requests, and track proposed change requests. The change management process begins when the ISO or a stakeholder submits a web-based Proposed Revision Request (PRR). After an ISO review for completeness, PRRs are posted to the website, triggering a stakeholder review and comment period.
- Submit Proposed Revision Request (PRR)
- Comments period
Upon ISO acceptance, PRR becomes public and 10-business day comment period starts - Stakeholder meeting
PRR details and comments reviewed and discussed - Recommendation
ISO recommendation issued on PRR - Comments on recommendation
10-business day comment period open on recommendation - Stakeholder meeting on recommendation
PRR recommendation and comments reviewed - Final decision*

Stakeholders have the right to appeal the final decision of a proposed revision request (PRR). Upon appeal, an ISO executive appeals committee conducts a public session to hear stakeholder positions and has 21 days to post a decision.
