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.
