在面臨全球社會趨勢的急遽變化與激烈的競爭當中，許多來自內、外部不同面向的衝擊與挑戰，組織因應著風險情勢變化，要想統整全面局勢，除了有效運用資源外，更須憑藉領導者有效的領導能力帶領團隊。專案管理與一般管理不同，專案管理強調整合與應變能力，具有時間與經費限制，專案領導者需具有溝通、協調與激勵士氣的能力，以系統化方式整合各項資源，達成預定目標。專案領導者的領導能力，肩負影響專案成員對專案工作之投入表現及專案績效、目標達成與否的重任。專案領導者如何透過領導能力有效統整資源，運用個人特質與管理技巧，發揮最高領導效能，激發專案成員潛在能力，強化成員具有更積極旳工作態度與競爭力，並能有意願且積極進修與工作有相關的知識，以保持個人在專業領域中的不斷精進，對組織投入高度認同感並提升工作績效，增進產業競爭力，是為本研究深入探究之動機。本研究旨在探討專案管理執行過程中，領導能力、專案承諾與專案績效之關聯性，並針對研究結果提出建議，作為管理上的參考。 本研究以公營企業、法人研究機構或團體之公營部門、研發及顧問機構、學術單位、學校、醫療院所等法人機構團體等單位為主，以有實際參與專案經驗成員為研究對象，透過便利抽樣方式進行問卷調查，問卷收集其間為2016年2月至2016年3月，共發放150份問卷，回收問卷130份，有效問卷100份；並使用SPSS統計軟體作為統計分析之工具，就樣本資料以：因素分析、t檢定、單因子變異數分析、相關性分析、迴歸分析、中介效果分析等方法進行分析，研究結果發現： 1.領導能力對專業承諾具有正面的影響。 2.專業承諾對專案績效具有正面的影響。 3.領導能力對於專案績效具有正面影響。 4.專業承諾對領導能力與專案績效具有中介效果。 In recent years, leadership has become a major concern in project management literature. Project leadership is critical to project performance. Some project managers develop leadership competency to improve project success. These project managers are also evaluating professional commitment for ways to improve project performance. Research on leadership competency and its effect on professional commitment and project success should offer tangible evidence of advantages from developing leadership competency. However, no empirical study has been done on the associations among leadership competency, professional commitment and project performance. Thus, the primary purpose of this research was to investigate the relationships among leadership competency, professional commitment and project performance. In addition, this study explores the mediating role of professional commitment in the relationship between leadership competency and project performance. The data were collected from February to March 2016. A total of 100 valid questionnaires were analyzed. The results of this study are as follows: 1.Leadership competency has a significant positive influence on professional commitment. 2.Professional commitment has a significant positive influence on project performance. 3.Leadership competency has a significant positive influence on project performance. 4.Professional commitment has mediating effect in the relationship between leadership competency and project performance.
