Chapter 9: Measurement System Analysis (MSA)
Abstract: Measurement System Analysis (MSA) is a statistical method to evaluate the quality, accuracy, and precision of a measurement system (gauges, methods, software, personnel, environment) to ensure it provides reliable data for decisions, identifying variation sources like repeatability, reproducibility, bias, linearity, and stability, and confirming it's fit for use before impacting product quality . MSA helps separate measurement error from actual product variation, preventing costly mistakes in quality control, This video provides a detailed overview of Measurement System Analysis (MSA): Key Components & Concepts Accuracy (Bias): Difference between the average measurement and the true value. Precision : How close repeated measurements are to each other. Repeatability: Variation when the same operator uses the same gauge on the same part. Reproducibility: Variation when different operators use the same gauge on the s...
