The closing phase of project management is the final phase of the project lifecycle. This is the stage where all deliverables are finalized and formally transferred, and all documentation is signed off, approved, and archived1. The most important step of the project closing phase is getting formal sign-off and acceptance of the customer2. Because projects are initiated based on a business need and customer request. Therefore, if the customer does not accept the final outputs and product, a project cannot be closed2.
