What evidence would show effective PPQA implementation?

• A. Records of independent process and product quality reviews, nonconformity reports, and corrective action closures.
• B. Financial audits and budget variances only.
• C. Customer satisfaction surveys without process reviews.
• D. A schedule showing test execution dates with no QA activities.

Answer: (A)

Evidence that PPQA is effective comes from independent quality assurance activities that verify both process and product quality. Records of independent process and product quality reviews show QA personnel evaluating work separate from the project team, identifying nonconformities, and ensuring corrective actions are closed. Nonconformity reports provide a trace of issues found and the actions taken, while corrective action closures demonstrate problems were resolved and improvements implemented. This combination shows an ongoing, objective check on how processes are followed and how the product meets quality standards.

The other options don’t fit because financial audits and budget variances focus on finances rather than process and product quality; customer satisfaction surveys alone don’t reveal the independent reviews or issue closures tied to PPQA; and a schedule with test execution dates but no QA activities implies no independent quality assurance evidence at all.
