| Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 102 === In order to enhance companies’ competitiveness and keep sustainable development in the changeable environment, enterprises have to keep pursuing innovation and improving their weakness all the time. This study is to study a case company, which has manufactured many kinds of panels for more than 40 years. For facing the fluctuating market, the case company wants to enhance its competitiveness and earn more profits. Therefore, the case company took some actions, including implementing new manufacturing processes, shortening product development processes, adjusting the product-mix flexibly, and manufacturing high added-value products.
The motivation of this study was to investigate a project that was reported a poor quality issue. The quality issue could not be solved by the technology transferring company. The goal of this study was to organize a project team for solving this problem. With the implementation of quality projects for years, the project team of the case company used the five steps of Six Sigma, which consisted of Define, Measure, Analyze, Improve, and Control, to reduce the number of defects caused by manufacturing processes. The results of the project met customers’ satisfaction with products’ quality and improved orders’ filling rates.
Through the implementation of the project, this study showed that Six Sigma could improve performance of manufacturing processes and achieve the research purpose. The experience of this project could be viewed as a reference for managers to implement similar projects in order to create more economic profits in the future.
