Quality function deployment for environment: QFDE (2nd report)-verifying the applicability by two case studies

This paper reports the results from two case studies of DfE (Design for Environment) using QFDE (Quality Function Deployment for Environment). QFDE is a tool developed to support designers at early stages of DfE of assembled products by modifying QFD (Quality Function Deployment). One example is a design of an IC package, while the other is a design of an LCD (liquid crystal display). From these studies, it was proved that QFDE is applicable to an early stage of assembled product design, because the most important component from the viewpoint of the environment is identified and multiple DfE options are evaluated. At the same time, the most critical point for a successful use of QFDE was found to be recovering a difficulty to define the matrices required to achieve QFDE
