Six Sigma – Understanding Control Charts

Course Level 3: Advanced

Estimated Study Time: 2-3 hours

Statistical Process Control (SPC) is a process used to determine if a manufacturing or business process is in a state of statistical control. Control charts are very important tools used in this process as they help monitor the stability of a process.

The course begins by describing the main features of control charts. These features include the data points, a centerline (mean value), and upper and lower limits (bounds to indicate where a process output is considered ‘out of control’). Next, the course describes how control charts visually display the fluctuations of a particular process variable, such as temperature, in a way that lets the engineer easily determine whether these variations fall within the specified process limits.
