Close Project or Phase: This process involves finalizing all activities and formally completing the project or phase. A key activity is to "confirm that the defined project scope is complete." The scope baseline
which includes the WBS
is a primary input to this process
used to verify completion. (p. 123).
Section 5.5
Validate Scope: This process is about formalizing the acceptance of completed project deliverables. The WBS

Delivery Performance Domain: This domain addresses the activities and functions associated with delivering the scope and quality that the project was undertaken to achieve. Verifying that "the project deliverables have been completed and that the project has achieved its intended business value" is a key check before closure. (p. 69).
Section 4.3
Artifacts: The Work Breakdown Structure is described as a "hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables." It serves as the definitive record of what must be delivered. (p. 188).

Project Termination: This chapter details the closure process
emphasizing the need for a final report that confirms "all deliverables have been made to the satisfaction of the client." The verification process relies on checking against the initial project plan and scope
for which the WBS is the foundational document. (pp. 618-620).
