| Summary: | 碩士 === 國立交通大學 === 管理學院碩士在職專班工業工程與管理組 === 94 === It was very popular to find the applications of various kinds of quality tools apply on the products development or the production improvement in the industry. If we just use quality tool alone, that only has limited improvement. How to improve the design quality of product through a good procedure and simple method, it will be the most attention and major care for enterprises. This research is tried with the systematic view of “Design for Six Sigma (DFSS )” process, combine with the quality tools of Kano model, reliability prediction of electronic equipment (failure rate analysis) and environmental / reliability testing to improve the design quality of ODM electronic products.
We use an index YRR(One-Year Return Rate) from TL 9000 Quality Management System Requirements of the worldwide telecommunication industry to evaluate the measurable effect of product design quality. This DFSS procedure was practiced in M company actually. We find the average YRR result of ODM product family (with DFSS process) is better than OEM product family (without DFSS process). Its relative value can be up to 25 times of disparity and 1.12 sigma. On the application of DFSS, if we can fulfill the demand from customer and market, and use the resources of company effectively. That will contribute to develop out the method of product design to suit specified company, and then improve enterprise's competitiveness.
