Teams, Time, and Technology: Variations of Media Use Over Project Phases.

While the notion of task–media fit is inherent to most theories on communication in virtual teams, past studies have largely concentrated on single, isolated tasks—hence neglecting sequential and contextual effects of media use. Building on project management frameworks, this study abstracts from the task level to the broader and more practical level of project phases, linking these to changes in media use. In particular, the study illustrates the weekly use of communication media within 34 student teams during a 3-month project. In line with team process phase models, results showed differences in media use between project phases: While face-to-face communication decreased, the use of leaner media (i.e., telephone and chat) increased in later project phases. Moreover, the variation of media use within the project phases increased over time, emphasizing the temporal dynamics of task–media fit. Finally, implications especially for project managers and recommendations for further research are discussed. [ABSTRACT FROM AUTHOR]
