How corrective action, phase gates, acceptance, transition, and formal closure maintain control through the end of a project.
Execution manages work against approved commitments. Closing confirms that deliverables have been accepted and that operational, contractual, and knowledge-transfer responsibilities are complete.
| Stage | Control |
|---|---|
| Delivery variance | Investigate the driver, select corrective action, and communicate impact |
| Phase gate | Confirm readiness, required evidence, decision authority, and approval to continue |
| Deliverable completion | Verify acceptance criteria and obtain the required sign-off |
| Transition | Transfer ownership, support information, access, assets, or service responsibility |
| Closure | Archive records, close commitments, release resources, document lessons, and confirm final status |
Technical completion is not the same as accepted delivery. Phase gates and closure records preserve the decisions, evidence, and handoff information needed after a project team disbands.
