MSA (Measurement System Analysis)

A method for testing and validating the accuracy and precision of a measurement system. It measure the level of risk in its reliability generally from three perspectives: Accuracy, Repeatability, and Reproducibility. It's not just calibration, but a more formal and scientific analysis of that measurement system.
