The ongoing, cyclical process that clash detection is just one part of: regularly merging discipline models into a federated model, reviewing it (visually and through automated checks), logging every problem found as a tracked issue, assigning it to whoever needs to fix it, and confirming the fix in the next cycle. A single clash-detection run is a snapshot; Model Coordination is the repeating weekly or biweekly rhythm that keeps a project's models converging toward a buildable, conflict-free design instead of diverging further apart.
Issues are typically tracked with BCF files so every team can open exactly the same problem in their own software, at the exact camera angle and element it was found.
