To ensure continuity and stability in CBRA and trader IT systems, changes to the WCO DM should be minimal, be reached by consensus, and be driven by strong business needs.
The purpose of these procedures is to provide a method whereby requests for changes, deletions, and/or additions to the WCO DM (including business process and information models, data elements, codes, and message implementation guidelines (MIGs)) can be processed in a logical and co-ordinated manner through the IMSC.
