Considerable research attention has been devoted to understanding the importance of knowledge creation in organisations over the last decade. Research suggests that leadership plays an important role in knowledge-creation processes. Nonetheless, there is an important omission in knowledge creation research; namely, what are the underlying processes that underpin the implications of leadership for knowledge creation? This article aims to develop a theoretical model of leadership and knowledge creation by drawing on two contrasting leadership perspectives; that is transformational leadership and leader-member exchange (LMX), and the research on open-mindedness norms. Specifically, we argue why transformational leadership is related to knowledge creation, and also theorise how open-mindedness norms and LMX quality serve as underlying mechanisms to underpin the effect of transformational leadership on knowledge creation. We conclude with a discussion of implications of the model for theory and practice, and also suggest potential avenues for future research
