DFMEA and Assumptions

Abstract

Carl and Fred discuss a listener question about the assumptions that go into a Design FMEA, relating to manufacturing and assembly.

Key Points

Join Carl and Fred as they discuss assumptions that go into FMEAs, how they are determined and applied.

Topics include:

• Question: if the product meets dimensions, do we assume it works as intended?
• Question: does the Design FMEA assume the product is manufactured to specifications?
• Does the Process FMEA assume the design is good?
• Are there exceptions to these assumptions?
• What about tolerances, what assumptions are made?
• What about supplier parts? Does the FMEA assume incoming parts are good?
• Can the product design be good enough so that assembly adjustments are not needed?
• How do you address assumptions in Design and Process FMEA?
• Design for manufacturability and assembly can be functions in the Design FMEA.
• Should the DFMEA assume the user will operate or use the product within the specifications?
• The use of “what if” brainstorming
• Question: Do you assume the drawings are finalized, when doing a DFMEA?
