DescriptionDespite a large literature on leadership and team dynamics respectively, research examining leadership and knowledge-oriented team processes and outcomes has been limited. In this dissertation, I focused on transformational leadership (TFL) style and its influence on psychological and behavioral processes as well as team outcomes of performance and learning. Taking a multi-level approach to leadership, I examined TFL at both individual and team levels, and its relationships to collaborative norms, knowledge sharing, team goal commitment, individual learning and team performance. Results confirmed the roles of process variables as important mediating mechanisms between leader behaviors and team outcomes. In addition, I found that team knowledge sharing had particular relevance to team performance when tasks presented high levels of knowledge intensity. This dissertation extends our knowledge about effects of leader behaviors by attending to multi-level leadership processes and a knowledge-work boundary condition.
