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 focuses on making sure the manufacturing system consistently produces parts that meet specifications. It’s the overarching function that defines the processes, standards, documentation, calibration, and audits needed to ensure conformity. By establishing quality plans, process controls, and feedback loops, QA creates the environment where parts are built right the first time and any deviations are caught and corrected early.

Verification is the act of checking whether the product actually conforms to the requirements—often through tests or measurements. Validation, on the other hand, asks whether the part will function in its real intended use, which goes beyond simply matching specs. Inspection is a specific method used to evaluate a part against requirements, but it’s a technique within the broader QA framework rather than the whole function.
