[Approval Requirementsrefer to how the objectives, deliverables, project management documents, and other outcomes and results of the project will be approved. This is different from product acceptance criteriathat element describes how the product itself will be approved, whereas this element describes the requirements that must be met in order to approve the deliverables. An example of product acceptance criteria might be "All widgets must measure three inches." A deliverable approval requirement might be that the director of sales must approve a prototype before the project can proceed. This section might also contain the process and approval requirements of the project scope statement.]
