Quality Control (QC) is defined as...

• A. The Ongoing Measurement of Product Sales Performance
• B. Customer Feedback Analysis Only
• C. An Assessment of Quality Based on Internal Standards, Processes, and Procedures Established to Control and Monitor Quality
• D. External Audit of Suppliers

Answer: (C)

Quality control focuses on ensuring products meet defined quality standards by using internal benchmarks and formal processes to monitor and regulate quality during production. It’s about evaluating outputs against these internal standards and taking corrective actions when needed, rather than just looking at sales performance or collecting feedback. The option describing an assessment of quality based on internal standards, processes, and procedures established to control and monitor quality best captures this systematic approach. The other choices miss that element: measuring sales isn’t about quality in production, customer feedback analysis alone doesn’t implement ongoing process control, and external supplier audits relate to supplier quality rather than the internal QC process itself.
