Start Your Free Excel Course. These out of control points represent “special” or “assignable” causes of variation that should be investigated. 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).
