Abstract
Quality Functioni Deployment (QFD) is a useful planning process in new product development. It achieves the maximum custom satisfaction through translating Voice of the Customer (VOC) into voice of the engineer in the House of Quality (HOQ), and ensures the customer focus from house to house translation. In QFD, the relationship matrix and correlation matrix are important pars, which will influence the final priorities of the technical response. According to the traditional methods, these matrices are determined by the people’s experience and filled with ordinal numbers. It would inevitably result in inaccuracy and curtness. Design of Experiments (DOE) is employed to determine the effect of variables on the process. In this paper, the author puts forward the idea of integrating DOE into the process of QFD. This integration helps to produce scientific decision and robust product design. A famework on QFD/DOE is presented and explanations are also made.
