摘要

瞭解與確認使用者之需求，是軟體開發專案成立初期的首要任務。然而，在複雜度極高的軟體開發專案中，無法有效且正確地表達顧客需求，仍是今日軟體開發專案失敗的主因之ㄧ。因此，本研究將針對此點，應用品質機能展開( Quality Function Deployment, QFD )之品質管理手法於軟體能力成熟度整合模式( Capability Maturity Model Integration, CMMI )中，藉由品質機能展開可以有效地將使用者的需求轉換為符合品質特性之技術述語，進而將專案中所擷取之原始客戶需求，展開成為品質表，並運用品質機能展開，有效地達到從企劃初期便開始執行之品質保證活動。

本研究嘗試將QFD與CMMI結合，並以CMMI流程領域中的特定目標作為改善之目標，進行品質機能展開與能力成熟度模式的流程整合與建構，及導入流程對組織之助益評估。藉由QFD來有系統地獲取顧客需求，並將其轉換成對專案設計有直接助益的品質要素，來提高軟體專案產品與顧客的期望之相符程度，以間接提昇顧客對產品的滿意度，並減少在專案開發中，客戶需求改變所造成之專案異動成本。

The awareness and confirmation regarding the requirements of the users are the primary tasks in the initial stage of software development project. However, in the highly complicated software development project nowadays, ineffective and inaccurate expression of customer requirements is one of the main factors causing failures of project. Therefore, this research applies one of the quality management tools, Quality Function Deployment (QFD), to the Capability Maturity Model Integration (CMMI) for converting the customer needs into the technical measures effectively, and furthermore performs the quality assurance activities from the planning phase of the projects.

This research applies QFD to the specific goals of the process areas of CMMI for integrating the QFD into the processes of CMMI, and moreover evaluates the performance of the organization adopting CMMI. With systematic acquisition of customer requirements, those requirements can be transformed into the features of design and manufacture to fulfill the expectations of customers. In the long run, it can not only increase the customer satisfaction but also reduce the unexpected changing costs during the development of the software projects.
