The contingent effects of leadership on team collaboration in virtual teams

Abstract

Decision-making in virtual teams creates challenges for leaders to structure team processes and provide task support. To help advance our knowledge of leadership in virtual teams, we explore the interaction effects between leadership styles and media richness on task cohesion and cooperative climate, which in turn influence team performance in decision-making tasks. Results from a laboratory study suggest that transactional leadership behaviors improve task cohesion of the team, whereas transformational leadership behaviors improve cooperative climate within the team which, in turn, improves task cohesion. However, these effects of leadership depend on media richness. Specifically, they occur only when media richness is low. Our results also suggest that task cohesion leads to group consensus and members' satisfaction with the discussion, whereas cooperative climate improves discussion satisfaction and reduces time spent on the task. © 2010 Elsevier Ltd.
