Which function is typically used to verify that a manufactured part meets required specifications?

• A. Verification
• B. Inspection
• C. Quality Assurance
• D. Validation

Answer: (C)

Quality Assurance is the function that ensures manufactured parts consistently meet specifications by planning, documenting, and controlling how work is done. It creates the quality system—procedures, training, calibration, process controls, and audits—that makes conformity to requirements an ongoing, built-in part of production. Verification and inspection are important tools used within that system, and validation checks if the final product meets user needs, but QA is the overarching approach that ensures the entire process drives parts toward meeting specs reliably.
