The functions of Quality Control include the following, EXCEPT:

• A. Analytical control
• B. Inspection control
• C. Auditing
• D. Planning

Answer: (C)

Quality Control is about the hands-on, day-to-day actions that keep products meeting specifications: monitoring processes, measuring outputs, inspecting items, analyzing data, and taking corrective actions to prevent defects from slipping through. Auditing, on the other hand, is an evaluative activity that checks whether the quality system and its procedures are being followed and are effective. It’s about assessing the quality management system itself rather than directly controlling the quality of a specific product or batch. Planning fits into QC insofar as it sets up how QC will operate—defining procedures, sampling plans, and acceptance criteria. Because auditing is a broader, systemic activity rather than a direct quality-control operation, it is the one that doesn’t belong as a QC function.
