WebDFMEA tends to be used mainly for products, while FMEA can also be used for processes, procedures and services. The final major difference is that DFMEA tends to be much cheaper than performing FMEA at a later stage to correct a failure. Used from design through to end-of-life for products, processes and services. WebArrange the product according to the body structure, design the product shape and structure, and use tools FMEA, FTA and DRBFM to analyze the potential failure of the design, and take preventive measures to avoid the failure; Ensure the product meets the target of performance, project schedule, cost and other objectives.
One of the simplest ways to accomplish this is by breaking down the product design into systems and components, each with its own function, and organizing them in a design and function tree.
