Design of Experiments (DOE) techniques enables designers to. determine simultaneously the individual and interactive effects of. many factors that could affect the output results in any design. DOE. also provides a full insight of interaction between design elements; therefore, it helps turn any standard design into a robust one. Simply. put, DOE helps to pin point the sensitive parts and sensitive areas in. designs that cause problems in Yield.
