对许多组织来说，有效地实现信息技术项目的预期业绩仍然是一项重大挑战。因此，提高我们对各种因素如何影响项目绩效的理解是一个重要的研究目标。本研究提出并检验了信息技术项目绩效的时间模型。它表明，性能可以更好地理解，通过分离的风险因素为早期（先验）的风险因素和后期（紧急）的风险因素，并模拟前者对后者的影响。作为因变量的项目绩效是通过考虑过程（预算和进度）和产品（结果）两个组成部分来衡量的。该模型包括风险因素，项目管理实践和项目绩效组件之间的相互作用。该模型进行了测试，使用偏最小二乘分析的数据从194个项目经理的调查。我们的研究结果表明，TMPP增加了解释力相比，模型，风险因素直接链接到项目绩效。结果表明，识别，规划和管理先验和紧急风险因素的积极风险管理的重要性。结构性风险因素和随后的波动性之间的强有力的关系的发现表明，风险管理实践需要认识到先验和紧急风险因素的相互作用。研究结果证实了知识资源、组织支持和项目管理实践的重要性，并展示了它们相互加强的方式。
Efficiently delivering expected performance from information technology projects remains a critical challenge for many organizations. Improving our understanding of how various factors influence project performance is therefore an important research objective. This study proposes and tests a temporal model of information technology project performance (TMPP). It shows that performance can be better understood by separating risk factors into earlier (a priori) risk factors and later (emergent) risk factors, and modeling the influence of the former on the latter. Project performance, the dependent variable, is measured by considering both process (budget and schedule) and product (outcome) components. The model includes interactions between risk factors, project management practices, and project performance components. The model is tested using partial least squares analysis with data from a survey of 194 project managers. Our results indicate that the TMPP increases explanatory power when compared with models that link risk factors directly to project performance. The results show the importance for active risk management of recognizing, planning for, and managing a priori and emergent risk factors. The finding of a strong relationship between structural risk factors and subsequent volatility shows the need for risk management practice to recognize the interaction of a priori and emergent risk factors. The results confirm the importance of knowledge resources, organizational support, and project management practices, and demonstrate the ways in which they reinforce each other.
