品質機能展開已被廣泛運用於許多領域，諸如產品設計、製程設計以及專案開發。其可將 顧客需求轉換為組織的工程技術，經由工程技術的實踐，進而成功的達到滿足顧客需求。而 品質屋即是品質機能展開使用的操作工具。在此同時，可將工程技術予以排列優先次序並依 序實施。 然而，在大部分有關品質機能展開的研究，工程技術間關聯性的探討經常被忽略。此舉 將影響專案工作的執行順序，並延誤產品設計或專案開發的進度。針對上述的缺失，本研究 提出結合設計結構矩陣與品質屋的方法。最後，以一案例驗證本文提出方法的可行性。

Quality Function Deployment (QFD) is a widely used application utilized in many fields such as product design, manufacturing process design, and project development. It can convert customer requirements into a firm’s engineering characteristics which results to achievements showing great success and House of Quality (HOQ) is the manipulation tool for QFD. Meanwhile, we can prioritize the engineering characteristics in HOQ and then sequentially implement them to meet customer requirements. However, the consideration of correlation among engineering characteristics is often ignored in most of QFD application related researches. This usually affects the implementation sequence of the project tasks and results to delay or queuing in product design/project development. This paper presents a methodology based on Design Structure Matrix (DSM) and the absolute importance of engineering characteristics in HOQ which deals with the weakness mentioned. An example is illustrated to evidence the proposed methodology.
