摘要

風險認知在軟體專案管理中相當重要，本研究的第一個目的在於探討風險認
知的前置因子以及其對績效的影響，使用的前置因子為樂觀及自我勝任，第二個
目的則是驗證樂觀與自我勝任的關係，第三個目的則是驗證風險認知與績效的關
係。樂觀對軟體專案經理對於專案的風險認知有顯著正面影響，但對績效的影響
則不顯著，而樂觀對自我勝任有顯著正面影響，自我勝任對風險認知也有顯著正
面影響，風險認知對績效也有顯著影響。研究方法則以問卷法驗證各關係的存在，
測詴針對同個專案的專案經理、開發人員與使用者驗證模型，全概念以專案經理
的看法為主，惟最後在測詴風險認知至績效時，採用同一專案之利益關係人感受
到的績效，以期更加精確驗證。

Risk perception is very important in software management. There are three
purposes in this paper: finding the antecedent factors of risk perception and how they
affect performance, and proving the relationship between optimism and self-efficacy
in the MIS field, and prove the relationship of risk perception and performance. The
results show that optimism has a positive effect on risk perception and self-efficacy,
but it has no significance on performance. Moreover self-efficacy has a positive effect
on risk perception. Finally, risk perception has a positive effect on performance.
About the research method, we use questionnaires to test the model.
