Which set of methods reassures customers about the quality of products by meeting certain quality standards (such as ISO 9000)?

• A. quality control
• B. quality assurance
• C. Total Quality Management
• D. lean production

Answer: (B)

Quality assurance is about ensuring quality by following defined standards. It’s a proactive, process‑oriented approach that builds quality into how things are done, using documented procedures, training, audits, and process controls to meet standards such as ISO 9000. By establishing and following these standards, the company provides reassurance to customers that the products will conform to required quality levels. In contrast, quality control focuses on inspecting finished products to find defects after production, lean production concentrates on eliminating waste and increasing efficiency, and Total Quality Management is a broader philosophy of continuous improvement across the organization (with QA as part of that effort).
