Concept FMEAs are used to analyze concepts for systems and subsystems in the early stages.
Focus on potential failure modes associated with the proposed functions of a concept proposal caused by design decisions that introduce deficiencies (these include “design” decision about the process layout).
Include the interaction of multiple systems and the interaction between the elements of a system at concept stages (this may be operation interaction in the process).
Design FMEAs are used to analyze products before they are released to production.
Focus on potential failure modes of products caused by design deficiencies.
Identify potential designated characteristics called “Special Characteristics.”
Process FMEAs are used to analyze manufacturing and assembly processes.
Focus on potential product failure modes caused by manufacturing or assembly process deficiencies.
Confirm the need for Special Controls in manufacturing and confirm the designated potential “Special Characteristics” from the Design FMEA.
Identify process failure modes that could violate government regulations or compromise employee safety.
