What is Measurement System Analysis?
Not every organization is aware of the importance of understanding and quantifying the variation in measurement systems. Without a good measurement system, there is no real way of knowing what the output of a process really is! We may think that we are producing good parts based on measurements made only to find out that the parts are seriously defective or out-of-tolerance because the measuring device used is inaccurate, out-of-calibration, or not stable.
GR&R Studies are the most widely accepted techniques for evaluating the level of variation in a measurement system and determining if the evaluated measurement system is acceptable for use.
Measurement Systems Analysis Online Training
MSA (Measurement Systems Analysis) online training includes detailed tutorials on many measurement system analysis techniques including how to conduct and analyze GR&R (Gage Repeatability and Reproducibility) Studies. A GR&R is the accepted technique for evaluating the level of variation in a measurement system and determining if the measurement system is acceptable for use. Measurement System Analysis covers techniques for analyzing the variation within a measurement system, determining its suitability for use, and ways to improve measurement systems. The GR&R analysis techniques used in the MSA online training program are in compliance with IATF 16949/AIAG methods.
