According to the PMBOKĀ® Guide (6th Edition), the primary tool used to determine if project activities comply with organizational and project policies, processes, and procedures is a Quality Audit. This is a key tool and technique of the Manage Quality process (often referred to as Quality Assurance).
A quality audit is a structured, independent process used to determine if project activities comply with organizational and project policies, processes, and procedures. The objectives of a quality audit include:
Identifying all good and best practices being implemented.
Identifying all nonconformity, gaps, and shortcomings.
Sharing good practices introduced or implemented in similar projects in the organization and/or industry.
Proactively offering assistance in a positive manner to improve the implementation of processes to help the team raise productivity.
Highlighting contributions of each audit in the lessons learned repository of the organization.
Analysis of Distractors:
A (Look at the quality metrics): Quality metrics are an input or a measurement standard (e.g., number of defects, on-time performance). While they tell you what to measure, simply looking at them does not constitute a formal review of " compliance with policies and procedures. "
B (Validate the scope): This is a Monitoring and Controlling process focused on the formalized acceptance of the completed project deliverables by the customer or sponsor. it is about the " correctness " of the deliverable relative to the scope, not process compliance.
C (Review the quality checklist): A quality checklist is a structured tool used to verify that a set of required steps has been performed. While it helps in maintaining consistency, it is a component used during the work. A formal determination of overall organizational compliance is handled by the broader " Audit " function.
