DFA2 - Design for Automatic Assembly
DFA2 is A Method for Product Design.

Techniques known as Design for Assembly, DFA, have been used since the early eighties. Most DFA methods focused on product evaluation; however few DFA methods provide the user with information on how to design the product to avoid assembly problems.

DFA2 is based on a collection of design rules to provide information to the users on how o design the product. The design rules are aimed at Automatic Assembly, DFAA (Design for Automatic Assembly). The design rules are sequenced, starting from information regarding the whole object and continue with information for each part in the product.

Furthermore, DFA2 supports costs analysis to reveal the costs connected with the design concepts. The cost analysis is based on an activity analysis.

The first step towards de DFA2 method was described in Byron Carlsson (1998) and has since then, been furter developed. The method does not require necessarily a prototype, or an existing product, to redesign, it can be used already at the start of projects.
