Enterprise managers could no longer rely on outdated norms to evaluate product quality; they should consider the quality issue and introduce appropriate ways to improve product quality. As enterprises continue to introduce advanced technologies, the demand for higher manufacturing quality also rises. Lowering product defect rate is the top priority for enterprises, since customers can only be sufficiently satisfied with products of quality manufacturing and those with the lowest defect rate. Six Sigma was proposed by Motorola Company in 1987; since then, Motorola Company has made some effective improvements. Similarly, GE also started reformation in 1990, and had achieved tremendous effects. From then on, Six Sigma gained many enterprises’ attention. The introduction of Six Sigma also became an important component in business management. In light of this, this study aims to conduct case study on a Screen Printing company, and investigate how it applies the method of DMAIC to improve its manufacturing quality, as well as how it improves customer satisfaction, lowers the product defection rate and saves the production cost. Results of this study suggest that, the application of DMAIC could significantly minimize the defection rate of Screen Printing production as well as decrease the variance. It is suggested that, if companies could effectively and consistently employ DMAIC to improve the overall production quality, they could enhance their competitiveness and save unnecessary expenses.
