IS Leadership is distinctive from leadership in general because of the special interface between Information Technology and business. As the increasing complexity and interdependence in the Information Systems Development (ISD) context, this study proposes to examine the IS leadership from a distributed team level. Based upon Social Interdependence Theory, we argue that the inherent high level of positive interdependence in the ISD context determines the team members’ interaction patterns which result in team leadership and team learning. The empirical evidence will be collected to test the model. The study results will benefit the understanding of team leadership in ISD context and explore the relationship between team leadership and team learning.
