Optimizing product design using quantitative quality function deployment: A case study

Quality function deployment (QFD) is a systematic process to help businesses focus on customers. In recent years, many quantitative QFD methods have been developed. However, there have been few case studies reported on their use. In this paper, an attempt was made to examine the applicability of quantitative QFD in optimizing product design. A case study on personal computer design was conducted. The case study findings demonstrate that quantitative QFD can be successfully implemented in product design. The limitations are examined. Some practical suggestions on implementing quantitative QFD are offered.
