non normal process capability

Sometimes, your data are not normally distributed.  Our SPC for Excel software has the capability of handling non-normal process capability analysis. The data can be fit to one of 13 different distributions.

Our software generates histograms with distribution curves, plots the specification limits, handles one-sided specifications and generates all the capability statistics you need for non-normal distributions.
