新產品開發為企業持續發展重要營運活動之一,新產品的績效更與企業獲利有密切關係。在新產品開發過程中即對新產品開發專案績效予以適當評估將有助於整個新產品開發流程。來自於新產品開發專案團隊內部或外部之設計變更,將對專案績效產生正面或負面之影響,而透過專案管理行動的實施則可以降低因設計變更對於專案績效之負面影響。 本論文以個案研究方式,透過將不同類型新產品開發專案運作之資料與影響因素加以整理分析後,提出在新產品開發過程中,探討所發生之設計變更與專案績效之間關係時,必須考慮設計變更之來源與其內容、專案類型以及所處專案階段的組合狀況,以作為未來開發專案實務之參考。本個案研究分析認為適當運用溝通協調、知識與問題解決能力以及組織管理能力等專案管理行動時可以減少設計變更對專案績效之負面影響。
New product development (NPD) is one of the important operations for the sustainable company, and the performance of NPD is a very serious concern for the company profit making. Properly evaluating NPD project performance could greatly benefit the NPD process. During NPD, design changes from inside or outside of the project team will have great influences on the project performance. The negative influences of those changes on performance could be reduced through proper project management actions. This thesis performs a case study analyzing operating data and the influencing factors in different NPD projects to provide reference for future NPD project practices. The main outcomes of the study include the need for the combined considerations on the source and content of design change, the project type, and the stage of project while researching the relationship between design change and project performance. In addition, properly implementing project management actions including communication and coordination, knowledge and problem solving, and organization management abilities could reduce the negative influences of the design change on project performance during NPD.
