Using Control Charts

Control charts are a tool that can be used as a part of VPP.

A "control chart" is a graphic presentation of results compared with your goals or limits. A control chart is used to determine whether variations in the results of a process are random or systematic. It allows you to identify the non-random variations that corrections or changes can be made to eliminate the variations.

An article on the web site for the Hanford Nuclear Reservation provides an excellent, detailed description of how to generate and use control charts. The article starts by discussing the various types of control charts. It then provides a detailed description of how to create a control chart, including the required mathematics. This is followed by a description of how to analyse the information provided by a control chart.
