Calibration is a key element of a robust Quality Plan. Which option reflects this?

• A. Calibration is not considered.
• B. Calibration is performed only for fun.
• C. Calibration is a key element of a robust Quality Plan.
• D. Calibration applies only to software.

Answer: (C)

Calibration being part of a robust Quality Plan means that measurement accuracy is planned, managed, and traceable across the entire process. A solid plan specifies how every measuring instrument and software tool used in inspection or testing is calibrated, how often, what standards are used for calibration, who is responsible, and how the results are documented and acted on. This keeps data trustworthy, reduces process variation, and supports compliance with quality requirements and customer expectations.

Saying calibration is not considered, or is done “for fun,” or only applies to software contradicts disciplined quality practice. True calibration encompasses physical gauges, fixtures, instruments, and software-based measurement tools, all requiring scheduled calibration, traceability to standards, and appropriate corrective actions when readings are out of tolerance.
