DFA - Design for Assembly Index

Design for Assembly Index indicates how easy it is to assemble a component. It is calculated using the formula: DFA = 100 × Nm × tm / ta, where Nm is the theoretical minimum number of parts, tm is the minimum assembly time per part (s), and ta is the estimated total assembly time (s).
