Which term describes the system that plans and ensures quality across production and delivery?

• A. Purchasing
• B. Quality Assurance
• C. Six Sigma
• D. ISO 9000

Answer: (B)

The system that plans and ensures quality across production and delivery is called Quality Assurance. QA covers the structured activities and processes that establish quality requirements, set standards, and monitor outcomes to prevent defects and ensure consistent results from start to finish. Purchasing is about obtaining materials. Six Sigma is a rigorous defect-reduction methodology used within processes but not the overall system name. ISO 9000 refers to a family of quality management standards organizations can follow; it describes requirements for a quality system, not the term for the system itself. So the best fit is Quality Assurance.
