Click here to view the videos on how SPC for Excel handles the measurement systems analysis and gage R&R techniques.

Our SPC software, SPC for Excel, contains a Measurement Systems Analysis/Gage R&R component that determines if the measurement process is acceptable. It is based on the techniques outlined in Measurement Systems Analysis (AIAG), 4th edition, and Evaluating the Measurement Process (Wheeler and Lyday). The MSA/Gage R&R component is also available as a stand-alone product.

The SPC software contains the variable measurement techniques as well as the attribute measurement techniques. It includes the average and range method with all the charts highlighted in the AIAG manual on measurement systems analysis. The software also contains the ANOVA method for the variable measurement system. The range method for gage R&R is included as well, determining the bias and linearity of a measurement system. Finally, attribute gage R&R is included. The features in the software are shown below.

For more information on variable measurement systems analysis, please see our four part newsletter series from September - December 2007.
