During which process would stakeholders provide formal acceptance of the completed project scope?

According to the PMBOK® Guide, the process of formalizing acceptance of the completed project deliverables is known as Verify Scope (Note: In newer editions of the PMBOK® Guide, this is referred to as Validate Scope).

Primary Objective: The key benefit of this process is that it brings objectivity to the acceptance process and increases the probability of final product, service, or result acceptance by validating each deliverable.

Key Output: The primary output of this process is Accepted Deliverables. These are deliverables that have been completed and signed off on by the customer or sponsor, indicating formal acceptance.

Comparison with Quality Control:

Verify Scope is primarily concerned with the acceptance of the deliverables by the stakeholders.

Perform Quality Control is primarily concerned with correctness of the deliverables and meeting the quality requirements specified for the deliverables. Quality Control is generally performed before Verify Scope, although they can be performed in parallel.

Why other options are incorrect:

Control Scope: This is the process of monitoring the status of the project and product scope and managing changes to the scope baseline.

Develop Schedule: This is a planning process focused on analyzing activity sequences, durations, and resource requirements to create the project schedule model.
