Describe the importance of carrying out DFMEA and DFMA reviews in engineering product development. What are the key outcomes of these reviews?

Solution

Design Failure Mode and Effects Analysis (DFMEA) is used to uncover design risk, which includes possible failure, degradation of performance and potential hazards. The DFMEA is typically the first FMEA tool used in product development. When performed properly, there are many benefits of DFMEA.

DFMA is used as the basis for concurrent engineering studies to provide guidance to the design team in simplifying the product structure, to reduce manufacturing and assembly costs, and to quantify improvements.

Review outcomes

DFMEA

–Early identification of the ways the product design can fail

–Rational prioritization of potential failures so that corrective/preventive action and/or redesign can be accomplished before risk and cost can escalate

–Smoother production ramps

–Enhanced system reliability once countermeasures are implemented

–Reduced development, production and warranty cost

–Higher customer and end-user satisfaction

DFMA

1.Estimation of manufacturing cost

2.Reduction in cost of components

3.Reduction in cost of assembly
