Quality function deployment for environment: QFDE (1st report)-a methodology in early stage of DfE

This paper presents a methodology of "Quality Function Deployment for Environment (QFDE)" applied to environmentally conscious design in the early stage of product development. QFDE has been developed by incorporating environmental aspects (Environmental requirements and Environmental engineering specifications) into QFD to handle the environmental and traditional product quality requirements simultaneously. Design engineers can find out which parts are the most important parts to enhance environmental consciousness of their products by executing QFDE phase I through phase II. Further, we developed a methodology to evaluate the effects of design improvement concerning the parts on environmental quality requirements as phase III and IV.
