Which component of the simplified quality scheme is described as monitoring only precision?

• A. TQMS
• B. QA
• C. QC
• D. CQI

Answer: (C)

Quality control is the part of a simplified quality scheme that focuses on the measurement process itself, ensuring repeatable and consistent results. In practice, this means running control materials with every batch and tracking the results on control charts to see if they stay within predefined limits. If the controls stay in range, the assay’s precision—the agreement of repeated measurements—is considered acceptable. If a control point goes out of range, it signals a potential imprecision or drift in the measurement process and prompts investigation. This emphasis on consistent, repeatable results is why quality control is described as monitoring only precision in this context. The other components serve broader aims: quality assurance oversees the entire process quality and compliance, CQI aims at ongoing process improvement, and TQMS covers the overall management system.
