Abstract: With the rapid development of information system and Internet, more and more collaboration teams are armed with the latest technology. Individual trust is vital to IT mediated team which is based on the emerging IT technology. This paper undertakes case study methodology, and investigates the sample case over three stages. Trend trust balance model and trust spider diagram are used to analyze how trust factors develop in different stages and the general trend of individual trust. It turns out that the change of individual trust has many features. Interviews are made in the end of the experiment to find out the reason of the change. We also found out that some temporary and uncertain factors have influence on individual trust.The reasons for the trend of trust development has also been discussed.

摘要： 随着互联网和IT技术的发展，团队协作越来越趋于信息化。基于新兴IT技术平台的协作方式使得团队中的个人信任问题显得尤为重要。此研究采用情境实验法的研究方法，对基于国际管理学界最新的信息化建导技术进行的创新型协作的团队样本分三个阶段进行了跟踪式调查，并采用信任平衡趋势图和蜘蛛图模型，对所得数据进行分析，得出了信任因素在不同阶段的发展变化的四对平衡相互关系，以及个人信任在协作过程中的整体发展趋势。研究还得出了个人信任在协作过程的不同阶段具有稳定性，非理想值性，以及易扰性的特征。实验末期又进行了半结构式访谈，验证了前两个模型的结果并深入分析了影响个人信任发展的影响因素。研究发现，一些临时性的、不确定因素会影响个人信任。此外，此研究还深入讨论了产生信任发展变化的原因。
