Issue Ownership in Design Coordination

Why Ownership Prevents Stalled Issues

A coordination issue stays open when no one knows who is supposed to close it. Assigning a single owner is not enough — different people own different parts of the resolution. The DisciplineBridge Review Manual uses five roles so that every issue has a clear path from question to closed.

The Five Roles

• Reviewer — Checks the proposed answer against their own discipline. A reviewer does not decide; they confirm or flag a problem.
• Decision owner — Accountable for the final answer. Only the decision owner can choose between options when reviewers disagree.
• Action owner — Implements the agreed change in the model, drawings, or documentation. The action owner turns the decision into a deliverable.
• Affected party — Must confirm that the change does not break their scope. An affected party is not a reviewer of the answer itself but of its side effects.
• Final approver — Signs off that the issue is closed for all disciplines. The final approver is the last check before the issue leaves the coordination log.

Assigning Roles

When an issue is opened, name all five roles at once. If a role cannot be named, the issue is not ready to work. The most common mistake is naming a decision owner but leaving the affected party blank — the change then breaks a scope that no one checked.

Closing an Issue

An issue is closed only when the final approver signs off. Reviewer approval alone is not closure. If the action owner has not yet implemented the change, the issue stays open even if the decision is agreed. Closure means the decision is made, implemented, confirmed by the affected party, and approved.
