Measurement System Analysis

Measurement System Analysis (MSA) is a structured process to evaluate the accuracy and consistency of measurement tools and methods. It ensures that data collected from instruments or procedures reliably reflect the true characteristics of what’s being measured. By analyzing factors like repeatability (getting similar results under the same conditions) and reproducibility (getting similar results across different users or devices), MSA helps identify and reduce errors. This is essential in quality control, process improvement, and decision-making, ensuring confidence that measurements are valid and trustworthy.
