Question P-Diagram (Parameter Diagram) in FMEA Preparation

Where does the " P " stand for in " P-diagram "?

A P-diagram is used as preparation for FMEA to show the interfaces and the " noise factors " of a system.

Best regards,

Antoine

"P" in "P-diagram"

Thanks Howard,

That why I asked the question in the first place because I did not find it myself while running through the material.

Best regards,

Antoine

Never heard of it before but my best guess would be "Process diagram" (whatever that might be in Ford's terminology).

Re: P-diagram in FMEA preparation - What does the "P" stand for in "P-diagram"?

Gentlemen,

I am working for FORD Motor Company and just wrote an article about p-daigrams.
It has been published in the ATZ worldwide June 2006.
I will try to attach this article as a PDF-File.

Re: P-diagram in FMEA preparation - What does the "P" stand for in "P-diagram"?

Hi guys, Google to the rescue as usual, a P-Diagram is a Parameter diagram.

The Parameter Diagram (P-Diagram) takes the inputs from a system/ customer and relates those inputs to desired outputs of a design that the engineer is creating also considering non-controllable outside influences. The P-Diagram, is a useful tool in brainstorming and documenting:

* Signal Factor(s)
* Response Variable or Ideal Function
* Control Factors, and
* Noise Factors
* Error States (or the failure modes)

A P-Diagram is essentially a schematic diagram that encompasses signal factor, control factor, noise factor and response variable.
