Measurement System Analysis (MSA)
Measurement System Analysis refers to methods used to evaluate the measurement systems (combination of gauges, standards, methods, software, personnel and/or environment) and determine whether we can trust our data. The evaluation of measurement system should be done prior to capability analysis, control charting or any other analysis to prove that the measurement system is accurate and precise, and the data are trustworthy. The five parameters to evaluate during MSA are resolution, bias, linearity, stability, precision (repeatability and reproducibility)
Attribute Agreement Analysis
Attribute Agreement Analysis is the type of Measurement System Analysis (MSA) that is used to quantify how well an attribute (discrete) measurement system is working.
Gage R&R is the type of Measurement System Analysis (MSA) that is used to quantify how well a variable (continuous) measurement system is working.
