measurement system analysis (MSA)

Measurement System Analysis (MSA) evaluates the accuracy and reliability of a measurement process. It identifies how much of the variation in measurement results is due to the measurement tools or methods versus actual changes in the item being measured. By assessing factors like consistency, precision, and accuracy, MSA ensures that data collected are trustworthy for making informed decisions. Essentially, it helps confirm that the measurement system provides stable, precise, and accurate readings, minimizing errors that could impact quality, production, or process improvements.
