隨著科技的迅速發展，製程技術也日益成熟，企業之間的製造能力和品質水準之間的差距逐漸縮小。面對競爭激烈且快速變化的市場環境，企業在思考如何快速回應市場需求與變化時，除了制定正確的市場策略和持續提升研發能力外，產品開發管理效率和品質也逐漸成為產品開發成功與否的關鍵因素。有鑒於此，本研究的主要目的是以「精實思維」為基礎，發展出一套評估工具，提供精實專家用於評鑑企業在產品開發流程與系統，以便分析在產品開發過程中所面臨的各種問題。作為企業推動精實研發管理改善之參考依據。
本研究採用混合研究方式，結合質性研究與量化分析，將研究執行過程分為兩個階段。第一階段是評估準則的建立與完善。首先，採用文獻分析法，蒐集相關精實開發文獻，作為評估準則的基礎架構。接下來，使用德爾菲法建立專家問卷進行準則修訂，經過共計三回合的專家問卷調查，最後完成「精實研發評估準則」的工具建構。第二階段為進行實證研究，以驗證評估準則的適用性和完整性。此階段包含實際應用評估的準則，對個案公司的產品開發流程進行評估。接下來，透過全體專家的共同討論，提出「精實研發評估報告」，然後再由個案公司的員工針對報告內容給予意見回饋與評價。
最終，本研究確立三個主要構面，共計有32項準則。分別為構面A「開發流程」：涵蓋將客戶需求轉化為產品開發過程的12項準則。構面B「人員管理」：包括員工管理和組織內部學習模式的11項準則。構面C「工具技術」：涉及產品開發中的軟硬體設備和技能提升的9項準則。本研究結果基於理論基礎並經過實證過程，協助企業識別改善機會，引導企業優化產品開發流程，提升開發效率和品質。此外，也有助於逐步推動企業實行精實研發方法，促進精實研發思維之發展與推廣。

With the rapid advancement of technology, process techniques have also matured, narrowing the gap in manufacturing capabilities and quality standards among enterprises. Faced with a highly competitive and rapidly changing market environment, when contemplating how to respond quickly to market demands and changes, apart from formulating the right market strategies and continuously enhancing research and development capabilities, the efficiency and quality of product development management are gradually becoming key factors in the success or failure of product development. In view of this, the primary objective of this study is to develop an assessment tool based on "lean thinking" to provide lean experts with the means to assess an enterprise's product development processes and systems. This tool is intended to analyze various issues encountered during the product development process, serving as a reference for companies seeking to improve their lean product development management.
This study adopts a mixed research approach, combining qualitative research and quantitative analysis, and divides the research process into two stages. The first stage involves the establishment and refinement of assessment criteria. Initially, a document analysis is conducted to gather relevant literature on lean product development, serving as the foundation for the criteria framework. Subsequently, the Delphi method is employed to create an expert questionnaire for criterion revision. Through three rounds of expert questionnaire surveys, the construction of the " Lean Product Development Assessment Criteria " is ultimately completed. The second stage consists of empirical research aimed at validating the applicability and completeness of the assessment criteria. This stage involves the criteria for practical application assessment and the evaluation of the case company's product development process. Subsequently, a "Lean Product Development Assessment Report" will be generated through collective discussions among all experts. Afterward, the employees of the case company will provide feedback and evaluations on the report's content.
In the end, this study establishes three main dimensions, totaling 32 criteria. These dimensions are as follows:Dimension A, "Development Process": Encompasses 12 criteria related to transforming customer requirements into the product development process.Dimension B, "Personnel Management": Includes 11 criteria related to employee management and organizational learning patterns within the organization.Dimension C, "Tools and Technology": Involves 9 criteria related to software, hardware, and skill enhancement in the product development process.The results of this research, grounded in theory and validated through empirical processes, assist businesses in identifying improvement opportunities, guiding them to optimize their product development processes, and enhancing development efficiency and quality. In addition, this research contributes to gradually promoting the implementation of lean product development methods within enterprises, fostering the development and dissemination of lean thinking.
