Control Charts & The Balanced Scorecard: 5 Rules. Control charts can be used as part of the Balanced Scorecard approach to account for an acceptable range or variation of performance. If you choose to do this, there are five key quality control rules to keep in mind when considering using control charts at your organization: Also called: Shewhart chart, statistical process control chart. The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. A less common, although some might argue more powerful, use of control charts is as an analysis tool. The descriptions below provide an overview of the different types of control charts to help practitioners identify the best chart for any monitoring situation, followed by a description of the method for using control charts for analysis. Control charts, also known as Shewhart charts (after Walter A. Shewhart) or process-behavior charts, are a statistical process control tool used to determine if a manufacturing or business process is in a state of control. It is more appropriate to say that the control charts are the graphical device for Statistical Process Monitoring (SPM).
