Control charts are very important tools used in Statistical Process Control (SPC) to determine if a manufacturing or business process is in a state of statistical control, that is, they help monitor the stability of a process. Alison’s courses teach the learner all about control charts for variables including 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.
