品質機能展開(QFD)是一個新產品開發與品質管理的系統化工具，具有機能整合的特性，提供一種結構化的溝通協調方式，促使各機能團隊合作，被廣泛的用於持續改善產品品質。本研究找尋最佳產品品質特性組合，應用影響矩陣(Influence Matrix)處理QFD的相依性評比資訊，補強品質屋(HOQ)，使展開過程更加周延。 在方法論上，結合QFD與影響矩陣為架構，應用在產品設計過程。首先透過QFD分析顧客需求，接著使用影響矩陣定義HOQ中顧客需求與工程規格的影響力，最後結合關係結構圖(Causal Network)解釋顧客需求與工程規格之間的因果關係。透過此結構化的產品設計模式，以滿足顧客需求、增加設計規格的精確性並減少新產品開發時間。 Quality Function Deployment (QFD), a systematic tool of new product development and quality management, has the property of functional integration. It provides a structural approach for communication among different developers to facilitate the interaction and cooperation of cross-functional teams, and it is now widely used to keep product quality improved. This paper applies Influence Matrix dealing with inter-dependent ratings in QFD to seek for the optimal combination of product quality characteristics, enhancing HOQ, and thus ensure the deployment more comprehensive. In the methodology, this paper presents the integrated system of QFD and Influence Matrix to develop an applicable structure in the process of product design. The approach, first, using QFD analyses the Customer Requirements. Then, adopting Influence Matrix defines the influence of Customer Requirements and engineering specifications in HOQ. Finally, combined with the Causal Network, QFD attempts to illustrate the cause-and-effect relationships that exist between Customer Requirements and engineering specifications. By this structured model of product design, the proposed integrated framework will achieve the goals of maximizing customers’ satisfaction, increasing the preciseness of design specifications and shortening the time for developing a new product.
