At what point does project execution transition to project closing?

The transition from project execution to project closing takes place when project deliverables are accepted by the primary customer. This acceptance signifies that the project has achieved its objectives and that the deliverables meet the agreed-upon specifications and quality standards. It marks a critical milestone in the project life cycle, as it indicates that the project's goals have been fulfilled from the client's perspective, allowing the team to begin the formal closure process.

Once the deliverables are accepted, the project team can focus on closing activities, such as finalizing contracts, completing documentation, and conducting retrospectives. This acceptance serves as a clear and definitive point to transition into closure, helping ensure that all stakeholders are aligned and satisfied with the project's outcomes.

Other options, while important elements of project management, do not represent the primary transition point. For instance, finalizing the budget is more related to planning and control rather than closing. Completing documentation is necessary for closure, but it follows the acceptance of deliverables. Conducting a project retrospective is an important step for learning and continuous improvement but occurs after the acceptance of deliverables, not as a trigger for project closure. Thus, acceptance by the primary customer is the pivotal moment that transitions a project from execution to closing.
