Organizations have moved from a face-to-face team environment to a virtual team environment using communication technology during the last decade. More and more workers use asynchronous tools (including email, discussion groups, information sharing tools, and group calendaring systems), and synchronous tools, such as instant messaging and web-based chatting features, to coordinate and share information with people within and outside of organizations. This empirical study on how virtual teams work, integrating mobile devices with web-based group communication for decision-making tasks, examines which technologies and communication modes are the best for distributed group teamwork, and, mainly, what are the predictive characteristics making mobile group communication successful. This thesis includes research motivations and research questions, followed by a theoretical framework based on existing theories and an extensive literature review, methodology, and data analysis. The last part is the results with conclusions and contributions of this study.

Further work should focus on dispersed virtual teamwork using different communication modes and technologies depending on the characteristics of the tasks and members, and organizational cultures.
