在全球化競爭的壓力與產品壽命週期逐漸縮短的趨勢下，新產品開發已成為各大企業關注與投資的重點，更是提昇自我競爭力的重點策略之一。鑑於有效的新產品開發流程才能使產品在品質、交期與成本要求下順利完成，因此如何衡量分析新產品開發流程的績效，找出問題並加以解決，是為影響新產品開發流程績效改善的重要關鍵。六標準差設計是一種普遍應用於產品品質提昇的系統化步驟，本研究以此系統化程序結合績效矩陣與因素分析等方法，建立起一新產品開發流程績效分析模式，同時參考科技接受模式架構，以結構方程模式來驗證該分析模式的使用成效，藉以精進此績效評估模式的運作。本研究以某跨國性電子業廠商為研究對象進行驗證，期望能協助企業在新產品開發過程中進行績效評估、問題發掘、原因分析、改善策略擬定與執行，藉此持續改善的循環來提昇企業的競爭力。

With the pressure of intensive global competition and the trend of shortening product life-cycle, the procedure for new product development (NPD) have become the focus of business concerns and investment of large corporations and the key strategy to upgrade competitiveness of the corporations.
Effective NPD procedure can meet the demands on quality, time-to-delivery and cost limitations of the corporation. Measuring and analyzing the performance of the existing NPD procedure and pinpointing and resolving the problems of the existing NPD procedures is the key to improve the NPD performance to meet the corporation‘s demands.
Design for Six Sigma is a systemic procedure commonly used on improving product quality. This paper proposes a model to evaluate and improve the performance of NPD procedures by following the systemic procedure of Six Sigma and applying criteria defined by application of Performance Matrix, Factor Analysis and Theory of Constraints. Technology Acceptance Model is then apply to the resulting procedure such that the effectiveness of the resulting procedure can be evaluated and improved. The resulting model is then verified with real life NPD procedures from a multi-nation electronic product manufacturer. Such that corporative competitiveness can be enhanced through the elevating cycle of performance evaluation, problem excavation, causes analysis, and countermeasure determination and execution proposed by this paper.
