摘要

近年來，由於摩托羅拉、奇異等公司推行六標準差所獲得的卓越成果，使得國內外許多企業相繼推動六標準差活動，希望透過六標準差改善品質、獲得利益。然而，推行六標準差之首要步驟乃為選擇適合企業本身的六標準差專案，若沒有正確的選擇專案，將可能會導致專案不符合企業需求而無法達到預期的目標，也使公司對於資源的投入失敗。因此，如何選擇一個適合的六標準差專案來執行，對於企業顯得格外重要。

許多企業在執行六標準差時，通常不知該如何選擇適當的專案，本研究之目的主要是探討六標準差專案的選擇方法，考量專案本身之特性與企業組織之需求，協助企業找出可能執行的六標準差專案。並透過相關文獻之探討發展六標準差專案選擇的評估指標，建立評估之層級架構，以利用層級分析法(AHP)進行權重之分析，並透過專案選擇矩陣，依企業需求給予適當之評比，期望能夠找出適當的六標準差專案，以幫助企業在六標準差上的執行。本研究最後以一個案說明所提方法的適用性，並且利用Excel建置成一個六標準差專案選取軟體，以期幫助組織人員方便且迅速地進行六標準差專案之選擇。

In recent years, owing to the success of Six Sigma at Motorola and GE, many enterprises are implementing Six Sigma to improve quality and increase the profit. However, how to select an appropriate Six Sigma project is crucial in implementing Six Sigma. If the selected project cannot fit the requirements and goal of the enterprise, it will lead to failure in implementing Six Sigma. Thus, it seems extraordinarily important to select a suitable Six Sigma project.

Many enterprises usually don’t know how to select Six Sigma project. The objective of this study is to establish the Six Sigma project selection method. First, by taking into consideration the project characteristics and enterprise demand, the possible Six Sigma projects are deployed. Then, through literature review, this study develops the evaluation index and applies the Analytic Hierarchy Process (AHP) to build the framework of hierarchy. Next, the AHP methodology is employed to acquire the weights of criteria and factors in the evaluation framework, and the project selection matrix is utilized to obtain the rating score of the Six Sigma project. Hopefully, suitable projects can be found. Finally, a case study is provided to illustrate the applicability of the methodology. In addition, we use the Excel to build a Six Sigma project selection system to help the decision maker efficiently select the vital Six Sigma projects.
