在科技日益發達的生活中，運用顯示裝置將資訊傳遞，已是隨處可見的應用。市場上穿戴式手環、機上盒及面板應用商品需求逐漸擴大，消費者購買的商品品質需求已不復以往能使用即可，轉而代之的是種魅力品質的追求，商品的要求可與藝術品比擬，至少選擇的商品已無法接受一絲一毫的缺陷，就國內外知名大廠 Fitbit、Garmin、華碩、小米、華為等公司，對於產品品質的要求格外的謹慎。而個案公司所生產的OLED面板便是供應鏈中的其中一個環節。控制生產過程中的異常，單憑藉過程中的製程管制已無法滿足精益求精的良率目標，而是運用有效的方法並將之導入，確實的以P-D-C-A方法，使異常持續的改善以達成績效指標。
公司生產OLED產品已近 20 年，在業務單位或是客服單位常會聽到客戶的抱怨，往往是產品的效能表現或是功能不良的異常現象。因此，廠內的製程異常改善力道未到位，使得客戶抱怨聲音此起彼落，便會造成產品重工、停線或是損失賠償等巨大的損失。2017/12客戶端生產時發現異常現象來自於公司內的生產線，並向工廠說明此異常若不解決，在未來的損失會相當龐大，問題不僅需要快速且有效的解決，並且涵蓋了各部門的業務層面，包括製程、設備、品保、生管、製造以及廠務部門，有效的選擇並利用工具串聯公司各部門的品質改善手法，便是當下首要任務。
因此，本論文針對此個案導入六標準差之方法，首先建立專案團隊擬定章程目標，以D-M-A-I-C，即定義(Define)、衡量(Measure)、分析(Analyze)、改善(Improve) 與控制 (Control) 五大步驟，先了解客戶的聲音，在轉換為廠內的語言，逐步的將異常以專案建立，並運用品質的手法進行異常改善，最後有效的控制發生中的異常或是從未解決的問題，進而降低客戶的抱怨並提升客戶滿意度。

The evolution of technology has reached a point where pretty much anything is available at the touch of a button and it is also common to use display devices to transmit information. Thus, the demand for applications of wearable bands, set-top boxes and panels is gradually expanding. However, consumers are not satisfied with the quality of the products only being usable. Consumers are expecting the products to be flawless, a slightest defect is not acceptable. Well-known domestic and foreign manufacturers, such as Fitbit, Garmin, Asus, Xiaomi and Huawei, have high standarders for product quality. Also, the quality of the OLED panels produced by the company, mentioned in the case study is the most important factor in the supply chain. Only controlling abnormalities during the manufacturing process can no longer meet the high-yield goal. Therefore, an effective method is introduced here, the P-D-C-A method is used to improve quality performance to achive peroformance targets.
In the case study, the company has been producing OLED products for nearly 20 years. Sales Department and Customer Service Department in the company would always receive the complaints from the clients about effectiveness and performance of the products. Therefore, if the manufacturing processes was not improved in time this would result in increasing of rework, down time, and a huge financial loss.
In December, 2017 a client complained an abnormality occurred within the company’s production line during assemble. The client claimed that if the abnormality could not be solved, the loss in the future will be huge. Since this abnormality needed to be solved quickly and effectively, the first task was to utilize the right method in improving the quality. Most departments in the company were involved, including manufacturing process, facilities, quality assurance, production management, manufacturing departments, etc.
Therefore, this study introduce Six Sigma to the case. The first step is to establish a project team and applying D-M-A-I-C five steps to set the objective, which stands for Define, Measure, Analyze, Improve, Control respectively. The company should listen and understand the clients’ complaints first, then transfer them into company’s internal language and gradually build a project over the abnormalities. At last apply the quality improvement method to solve the problem effectively.
