Abstract: By manipulating task types and task interdependence, a simulated experiment was conducted to investigate the development of three performance process modes among virtual teams. The results showed that: (1) Three performance process modes had different effects on team’s task performance. Team members could set exact goals during the whole process. The method modes only had significant effects on team performance at stage 1 and stage 3 while the trust modes had significant effects at the first two stages. The effect on team performance was moderated by the team practice and learning at the last stages. (2) The task performance of different interdependent teams was not significant in behavioral tasks but significant in conceptual tasks. Moreover, the task interdependence had different effects on performance process modes on different types of tasks.

Key words: task interdependence, task types, performance process modes
