Note: This step would normally not occur when performing the FFDM, It is included here to offer a design on which the FMEA can be performed. In the actual FFDM, the first physical model would already exhibit functionality and/or componentry to address possible failure modes. In this case, the initial physical design does not address any possible failure modes.

To succeed in the product development market today, firms must quickly and accurately satisfy customer needs while designing products that adequately accomplish their desired functions with a minimum number of failures. When failure analysis and prevention are coupled with a product’s design from its conception, potentially shorter design times and fewer redesigns are necessary to arrive at a final product design. In this article, we explore the utility of a novel design methodology that allows failure modes and effects analysis (FMEA)-style failure analysis to be conducted during conceptual design. The function-failure design method (FFDM) guides designers towards improved designs by predicting likely failure modes based on intended product functionality.
