Dynamic Process Performance Charts

The BIS.Net Team BIS.Net Team

Dynamic Process Performance Charts are an advanced form of Change Analysis and highly popular. They combine changes in both the average and standard deviation over time and display this information in a manner that enables the analyst to see the contribution to non-conformance. Applications are in quality assurance, process control, health and fitness and in general any application which must fall inside specification limits., although they are equally useful in the absence of specification limits.

To visualize the effect of changes in the average and standard deviation, color coded ‘D’s are used, as shown in the image below. Th effect of the instability can then be easily seen.
