新產品測試量表發展:產品測試與開發人員的應用工具

Abstract

在產品生命週期日益縮短、顧客需求快速變化的市場環境下，企業若欲提升新產品的成功率，應善用產品測試流程，有效地評估產品是否具備上市條件，而現較多測試工具聚焦於特定階段或功能驗證，缺乏整合性評估架構，亦難以同時考量市場接受度與永續趨勢。本研究目的為建構應用於新產品開發流程中產品測試階段的評估量表，協助企業在產品正式上市前，有條理的檢視與調整，以提高產品成功上市的可能性，研究以階段關卡模型第四階段—測試與驗證為理論基礎，並考量企業實務需求與永續發展趨勢，初步歸納出五大構面，設計三十題題項。前測階段回收44份問卷，進行探索性因素分析後，篩選出十一題，萃取三個構面，分別為永續性、市場需求度、使用者便利性；後測共回收 365 份樣本，並透過驗證性因素分析確認模型結構，結果顯示正式量表具有良好的信效度與模型適配度，與既有產品測試量表相比，本研究不僅涵蓋使用者導向與市場觀點，亦納入永續性考量，突顯新產品測試程序中對環境與社會責任的重視，除此之外，本研究分析不同背景受測者之評價差異，發現產品測試相關能力較依賴實務與跨部門合作經驗，而非單純取決於年資或職務層級。本研究所建在產品測試之量表，可作為企業前進行自我檢核的工具，有助於辨識潛在風險、發現測試盲點，並提前進行資源調整與決策規劃，也可作為內部溝通與跨部門協調的參考依據，提升新產品開發過程的整體執行效率與上市成功率。In today's fast-changing market with shorter product life cycles, companies must improve their product testing abilities to increase the success rate of new launches; however, existing tools mostly focus on specific stages or functions and lack a holistic view that considers market acceptance and sustainability. This study aims to develop an evaluation scale for the product testing phase in the new product development (NPD) process. Based on the Stage-Gate model’s fourth stage—Testing and Validation—and incorporating business needs and sustainability trends, five initial dimensions and 30 items were proposed.After collecting 44 pre-test responses, exploratory factor analysis refined the scale to 11 items across three dimensions: Sustainability, Market Acceptance, and Ease of Use. A final survey with 365 responses confirmed the model structure through confirmatory factor analysis, showing good reliability and fit. Compared to existing tools, this scale uniquely integrates sustainability with user and market perspectives. It also reveals that product testing capability depends more on practical and cross- functional experience than on job level or seniority.The product testing scale that was developed in this study can serve as a tool for companies to conduct internal reviews before launching new products. It also helps identify potential risks, discover gaps in the testing process, and adjust resources and planning.
