DFSS應用在新產品開發模式之研究與探討
On the study of the implementation of Design For Six Sigma in New Product Development
摘要
如何快速成功研發新產品是目前許多企業所關心的重要議題，特別是在技術以及顧客需求快速變動的壓力下，企業必須在短時間內快速研發新產品，以較低成本推出較高品質的新產品，使產品能在市場提高佔有率，為企業帶來獲利。因此新產品研發的工作不再是研發部門的單一工作，而是跨功能部門的一個相互合作。由於參與的部門、人員多了，因此新產品開發所需耗費的成本也相對提升。因此如何有效降低成本、縮短產品上市時間及提升品質是一項重要的議題。而要縮短新產品研發/設計及試作時間及以達到量產的規模，其中關鍵除了研發/設計的能力與製造的效率之外，更重要的是新產品品質。DFSS是使用於設計新產品、服務與流程時的一種手法，可確保產品及服務能達到顧客期望，替組織節省時間、改進品質，增加財務效益。本研究目的有三：1.整理出適合的DFSS流程及工作項目；2.整理出適合電子產品的一般性新產品開發流程及工作項目；3.找出對於導入DFSS流程關聯程度高的新產品工作項目。因此本研究先透過文獻探討整理出適合企業界的新產品開發與DFSS導入流程及工作項目，利用模糊德菲法找出導入DFSS流程適合的工作項目，最後利用灰關聯分析對DFSS流程關聯程度高的新產品開發工作項目進行排序，找出各階段之關鍵屬性。

How to develop a new product rapidly and successfully is a major issue that many enterprises concern about the most. Especially, under the pressures from the fast changes of technology nad customers’ demands, the enterprises needs to provide better products in shorter cycle time and at cheaper cost in order to increase the market share as well as bring more profit to the enterprise at the same time. Therefore, the development of the new product is not only the challenge to the R&D department, but also a cross- functional job among all the departments within the company. To reduce such cost effectively, shorter the time to market and also improve the product quality are very important tasks. Besides reducing the cycle time on the new product’s development and the raising of performance of the mass need in production stage, the performance of the new product development is also playing a key role. DFSS is a method the design of a new product, service and process, which can assure the output of a product or service can achieve customer’s needs and expectations, in the meantime it could reduce the cycle time, improve quality as well as increase the financial benefits. There are three purposes in this research：to define the suitable DFSS process, to identify the DFSS action items to find out the suitable stages of process and the related action items for the development of new electronic product, and to identify the relationships between the action items on each stage of new product development and on the stage of DFSS process. Therefore, through the literatures reviews, we first identify the proper implementation process to adopt DFSS in the new product development of the industries. Then, in using of Fuzzy-Delphi method to identify the suitable action items of DFSS processes. And, finally, Gray relation analysis is used to analyze the action items of the DFSS processes with the action items of the new product development process.
