摘要

使用風險管理工具有助於改善軟體專案績效和降低專案失敗率，然而，根據文獻少有學者探究影響專案經理使用風險管理工具意願之因子。針對這個議題，本研究考慮過去文獻所列的相關因素，來擴充科技接受模型並驗證。另外，本研究以國內曾經使用或充分瞭解風險管理工具的IT專案經理作為研究對象，共蒐集97份有效問卷，使用相關係數、解釋力、驗證性因素分析和結構方程模型來檢驗模型的信度和效度，以及評估變數之間的關係。研究結果顯示，自我效能、主觀規範和滿意顯著影響專案經理的持續使用意圖，滿意同時受到自我效能和認知有用性正向影響，認知易用性則受自我效能和主觀規範顯著影響，此外，認知有用性受專案控制力影響。因此，我們提出的科技接受擴充模型對風險管理工具使用有很好的解釋力。

The usage of risk management tools offers great potential for improving the quality of software projects and reducing project failure rate. However, the main very few studies explore which factors influence project managers’ willing to use risk management tools while performing their projects. This study attempts to address this issue by developing and testing a modified technology acceptance model taking into consideration other relevant factors found in the literature. We conducted a survey of 97 IS project managers in order to understand continue using intention of project managers. Structure equation modeling was conducted to exam all constructs and hypotheses. Correlation, explanatory and confirmation factor analysis was performed to test the reliability and validity of the measurement model. The structural equation modeling technique has also been used to evaluate the relationship between variables.
The results indicate that self-efficacy, subjective norm and satisfaction positively affect the continue using intention of project managers. Both self-efficacy and perceived usefulness positively affect project managers’ satisfaction. Self-efficacy and subjective norm significantly affect perceived ease of use, and project control affects perceived usefulness. We conclude that the proposed model has better explanatory to the context of risk management tools usage.
