BPM Library updates
The reference document on the ISO website lists the updated BPMs in the library.
The ISO may unilaterally make and implement revisions to the BPMs in emergency circumstances, as set forth in Sections 22.4.3 and 22.11 of the ISO Tariff and in Section 2.6 of the Business Practice Manual for BPM Change Management. An emergency PRR will continue through the BPM change management stakeholder process to obtain stakeholder input on the revisions and make other recommendations, as necessary.
Please note that affected parties must register in order to submit a PRR or written comments.
