The Link Between DFMEA and Control Plans

A natural link exists between FMEAs and Control Plans.

The purpose of a Control Plan is to:

	Minimize variation
	Provide a structured approach for control
	Establish an effective reaction plan
	Document and communicate failures and successes
	Enhance customer satisfaction

The primary reason for developing a Control Plan from a DFMEA is to use the DFMEA for setting process control procedures and identifying primary control points in the production process

 A Control Plan linked to the DFMEA provides a structured documentation and communication vehicle for the process control group.

Key components of a Control Plan include the:

	The control factor.
	Specifications and tolerances of control factors.
	Measurement system or technique.
	Sample size and sample frequency.
	Control method.
	Reaction plan.
