Control plans provide a written summary description of the systems used in minimizing process and product variation. The intent of the Control Plan form displayed in this section is to provide an example of how this information can be documented.The control plan is an integral part of an overall quality process and is to be utilized as a living document. A Control Plan is a written description of the system for controlling parts and processes.
