What are repeatability and reproducibility?

Repeatability and reproducibility describe how consistent a measurement process is, i.e., the precision of measurements. Repeatability is the variation you see when the same item is measured multiple times under the same conditions—same operator, same instrument, same setup, in a short time. Reproducibility is the variation when measurements are made under different conditions—different operators, different instruments, or different setups—measuring the same item. If measurements stay close in both scenarios, the system has good precision. They aren’t about time-based drift, environmental factors, or how often you calibrate; those address other aspects of measurement but not the definitions of repeatability and reproducibility.
