Virtual teams are groups of geographically or organizationally dispersed co-workers that are assembled using a combination of telecommunications and information technologies to accomplish an organizational task. The characteristics of virtual teams have computer communication significantly more than face to face communication; team members are geographically and/or organizationally dispersed; members have a common goal and engage in interdependent works. And the three characteristics were used as the standards that we designed and constructed virtual team in experiment. Effective operation of the team depends on mutual trust among members, especially in virtual teams. The characteristics of trust development in virtual teams were discussed using scenario simulation approach. and the trust were dividided into six factors to reveal the characteristics of virtual teams trust development over stages by examining the relationships of the six factors in all stages. Scenario simulation approach was used to examine the virtual team trust development. Student teams are frequently used target users for researchers to test or evaluate techniques and models in the team decision and collaboration research area. we selected a five student teams from a university in which each of the teams aimed to do the same team project over two months. There were six students in a team, each using QQ, MSN and e-mail to communicate with each other. Each team had the same team project to evaluate and redesign a website. Each experimental team has a leader whose responsible are organizing discussion, urging members to fill out the questionnaire and keeping records of communication. The team collaboration is controlled in the network environment and team members are not allowed to discuss issues about the task face to face. The discussions were running twice a week, and the experiment was lasted for two months. We conducted three surveys during the two months: After the first online discussion; a month later; at the end of the experiment. At the end of the experiment, we conducted a in-depth interviews on each team, to capture reasons for the differences of individual trust development of each team.
