由於大環境的改變，公司間的競爭越來越激烈；顧客對新產品的需求也因為新技術的出現日益增加。為了因應全球化競爭及產品生命週期縮短的大環境，迅速及優異的新產品發展成為公司重要的競爭優勢。為了強化公司的競爭優勢，新產品發展已成為一重要議題。本論文著重於研究改善新產品發展的過程，探討影響新產品發展的關鍵因素，尤其是生產與研發間的關係。 本論文分為五個部分，第一章探討新產品發展的概念及基礎理論，說明新產品發展從單一功能政策進化為今日的跨功能性政策的一環。第二章對影響新產品發展的關鍵因素做詳盡介紹，說明跨功能性的整合將會是新產品發展成功的關鍵方法。第三章仔細討論研發與製造間的關係，並將兩者的角色由傳統的分別為單一部門功能的觀點打破，且將產品的設計與製程均視為新產品發展的重要功能，試圖詮釋將單一個人╱部門的知識與成功的新產品發展連結的可能性。第四章將探討知識傳遞的限制、知識管理及組織學習的基本理論。第五章將介紹重要的管理上、組織上及技術上的支援工具，並希望藉由這樣的分析能夠瞭解新產品開發過程中各關鍵因素間的關係。第六章將介紹實務上所使用的新產品開發觀念，這部分的資料是由個案訪問而來，選了三家不同產業具國際營運的公司為例，對實務做驗證。最後，提出一新產品開發的「最佳實務」，包括了重新定義新產品開發過程中的功能，並提出一良好管理新產品開發的建議。 / Nowadays the competitions among companies become more and more fierce due to the dramatic change of competitive environment. The demands of new products are accelerated by the emerging new technologies. The rapid and excellent new product development (NPD) has become a great strategic advantage to be accommodated to the global competition with shorter product life cycle. In order to enhance the competitive advantage, improving NPD has become a vital issue for companies. This thesis focuses on improving the NPD process. Factors influencing the NPD process are discussed in detail, especially the interface between R&D and production. The thesis is divided into five parts, starting with a general view on NPD in the first chapter. There it will be shown, how NPD has changed over the last decades from a traditional approach of functional-development to a cross-functional process today. Factors influencing this effective collaboration are presented in chapter two. In chapter three, the interface between R&D and production is directly scanned. It will be distinguished between the individual knowledge bases of the different departments. Process and product knowledge can be identified as the parts to be matched and will be illustrated. Consequently, the possibilities of linking those knowledge bases during NPD are shown. Chapter four will focus on the limitations of knowledge transfer and the fundamentals of knowledge management and organizational learning will be presented. In chapter five, supportive organizational, managerial and technological tools will be analyzed. The multiple views on NPD assure that all factors influencing the process are analyzed and proven according to their leverage on the process. In chapter six, currently used NPD concepts are outlined. The information presented was gathered through interviews carried out at globally operating companies who have technological centers and production sites in Sweden. To avoid focusing on NPD practices in an industry, the companies were chosen according to their product lines and customer segments. The final part will present best practices in NPD. This includes reconsidering all the discussed aspects and presenting a recommendation about how to organize NPD superiorly.
