Which of the following tools and techniques is used in the Verify Scope process?

According to the PMBOK® Guide, specifically within the Validate Scope process (historically referred to as Verify Scope), Inspection is the primary tool and technique used to obtain formal acceptance of the completed project deliverables.

Core Function: Inspection includes activities such as measuring, examining, and validating to determine whether the work and deliverables meet requirements and product acceptance criteria.

The Goal: The main objective of this process is to have the customer or sponsor formally sign off on the deliverables. Inspection confirms that the results match the documented scope and requirements.

Terminology: Inspections are sometimes called reviews, product reviews, audits, or walkthroughs.

Comparison with Other Options:

Variance Analysis (B): This is a tool used in Control Scope to determine the cause and degree of difference between the baseline and actual performance, but it does not facilitate formal acceptance of a deliverable.

Expert Judgment (C): While experts may be involved in the inspection, " Inspection " is the specific, named technique for this process.

Decomposition (D): This is a tool used in Create WBS to break down the project scope into smaller, manageable components.

The Validate Scope process differs from Quality Control in that Validate Scope is primarily concerned with the acceptance of the deliverables by the customer, while Quality Control is concerned with the correctness of the deliverables and meeting the quality requirements.
