本研究探討顧客參與程度與知識管理能力對軟體新產品績效的影響。在新產品開發中,顧客的知識與經驗被認為是競爭優勢的潛在來源。業者在各個新產品開發活動中採用顧客參與,且顧客的參與能有效提升新產品績效。此外,知識管理能力也被證實會影響組織績效。本研究以284家軟體公司為樣本,針對各公司專案經理或具經驗的專案成員,發放615份問卷,回收有效問卷78份,有效回收率為12.7%。利用集群分析與t檢定作假設的驗證,驗證結果顯示:顧客參與程度顯著影響新產品開發績效,包括成本控制、開發速度、品質的提升與市場績效的改善;企業知識管理基礎建設則顯著影響新產品開發的成本控制、開發品質與市場績效;知識流程管理能力則顯著影響新產品開發的成本控制與開發品質。並根據研究發現提出討論與建議。 Knowledge and experience of customers have been considered as the potential sources of competitive advantage in developing new product. Practitioners have allowed customers participation in various new product development (NPD) processes and found the participation of customers improving the performance of NPD. Besides, knowledge management capabilities were found to influence the performance of organization. Based on the list of software companies, 615 questionnaires were sent to the project managers or senior project members in 284 companies. 78 responses were received which yielded 12.7% response rate. According to the results of clustering analysis and t test, the degree of customer participation were founded to be significantly associated with all project performance on NPD. Besides, knowledge management infrastructure capabilities were found to be significantly associated with project performance of NPD on cost reduction, product quality and market share. However, knowledge process management capability causes the significantly impact on cost and quality. Finally, implication and limitation are discussed.
