Design For Assembling: The Evaluation Methods Of Hitachi, Boothroyd And Lucas

The product design that is best for function, for manufacturing, for assembling and for servicing results in the best product.

The stages of Design for Manufacture (DFM) and Design for Assembly (DFA) combine towards that integration in the form of Design for Manufacture and Assembly (DFMA). Some broad guidelines for DFMA are given in Table I.
