Process stability check with free excel template
Nelson rules are a method in process control of determining if some measured variable is out of control (unpredictable versus consistent).
The rules are applied to a control chart on which the magnitude of a variable is plotted against time. The rules are based around the mean value, the range and the standard deviation of the samples.
With this process-stability-excel-template-english-20150928.xlsx you can immediately check if your process follows the rules. If not, you have to analyse your process.
