move to sidebar hide from wikipedia the free encyclopedia product design methodology design for manufacture and assembly often abbreviated dfma or dfma is a product development approach that combines design for manufacture dfm and design for assembly dfa to simplify product structures reduce manufacturing and assembly costs and address production considerations early in design 1 the methodology developed through academic and industrial research in the late 1970s and 1980s then saw wider uptake through software tools and training 2 3 in 1991 geoffrey boothroyd and peter dewhurst received the u s national medal of technology and innovation for the concept development and commercialization of dfma 4 the term is also used in the architecture engineering and construction sectors where dfma emphasizes off site manufacture standardization and platform approaches history edit early research into assembly friendly product design and quantitative evaluation methods focused on estimating manual and automatic assembly times and on reducing part counts to cut assembly effort 5 in the early 1980s geoffrey boothroyd and peter dewhurst introduced design for assembly methods and associated software interest from large manufacturers helped spread industrial adoption and led to commercial offerings 6 a design for manufacture module followed in the mid 1980s the combined methodology dfma was popularized through textbooks training and analysis tools 7 in 1991 boothroyd and dewhurst were jointly awarded the u s national medal of technology and innovation recognizing their dfma work and its industrial impact 8 usage edit engineering product design and manufacturing edit dfma is used in concurrent engineering to guide simplification of product structures reduce manufacturing and assembly costs and quantify improvements the practice aims to identify measure and eliminate waste or inefficiency in a product design dfma is therefore often positioned as a component of lean manufacturing dfma is also used as a benchmarking approach to study competitors products and as a should cost input to supplier negotiations 9 academic reviews survey dfma methods across mechanical and electromechanical products they discuss measurable effects such as part count and assembly time changes and the timing of design decisions 10 dfma in construction edit while modernist architect le corbusier advocated industrialisation of construction in 1923 proposing a house is a machine to live in dfma as a concept in construction began to emerge in the 1990s as construction industry critics applied cross sectoral learning that looked at production theory integration of design manufacture and assembly and lean concepts and tools 11 in the early 21st century dfma began to be advocated by government and industry organisations 11 including in the uk the royal institute of british architects 2016 updated in 2021 12 and the infrastructure and projects authority 2018 13 in singapore the building and construction authority advocated dfma in hong kong the sar development bureau provided guidance 11 uk government construction policy has continued to advocate dfma approaches it appeared in the 2019 construction sector deal 14 the construction playbook 2020 2022 15 and the ipa s 2021 tip roadmap to 2030 16 in the 2020s procurement of construction projects based on product platforms sometimes called platform design for manufacture and assembly pdfma has been encouraged 15 16 the pdfma approach has been applied to prison projects constructed by kier group for the ministry of justice 17 18 and to delivery of a landsec commercial office building the forge in central london 19 constructed by mace and sir robert mcalpine 19 and designed by bryden wood 20 documented results and case studies edit independent reporting in the 1990s summarized typical dfma outcomes these include reductions in part counts and assembly time for products that underwent redesign using dfma methods and checklists 21 academic reviews synthesize dfma methods and measured effects across mechanical and electromechanical products 22 publisher provided case studies hosted by boothroyd dewhurst inc describe applications of dfma across sectors such as agricultural machinery aerospace components and medical diagnostics these are primary sources and should be interpreted accordingly 23 examples named by the publisher include projects at john deere itt and idexx 24 tools and software edit dfma methods are implemented in analysis tools one implementation is the dfma software suite from
