Parameter Diagramm Fmea. A structured tool that identifies the inputs from a system and relates those inputs to the desired system outputs while considering the controlled and uncontrolled factors the parameter diagram can provide important input to system and design fmeas. System elements und their functions are described and visualized in a simplistic manner.
Quality one international 1333 anderson road clawson mi 48017 ph. 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 it is a useful tool in brainstorming and documenting input signals noise factors control factors error states and ideal response. Creating a p diagram is an optional step when preparing a system or subsystem fmea.
Fmea works smoothly through the development phases when an investigation of past failures and preparatory documents is performed from its onset.
Parameter diagrams the ability to create parameter diagrams has been added in xfmea version 11. The parameter diagram p diagram is a block diagram which shows the connections between different parameters of a system. Ein p diagramm ist der ideale einstieg in eine fmea. Creating a p diagram is an optional step when preparing a system or subsystem fmea.
