Abstract

Leadership style is one of the most consistently studied determinants of project outcomes in the project management literature. This paper examines how transformational, transactional, laissez-faire, servant, and situational leadership styles influence project team motivation and, in turn, project performance. Drawing on established leadership theory (Burns, 1978; Bass, 1985) and empirical project management research (Turner & Müller, 2005; Müller & Turner, 2007), the paper synthesizes findings from peer-reviewed studies to argue that transformational and servant leadership styles are most strongly associated with intrinsic motivation, team cohesion, and superior project outcomes, while laissez-faire leadership is associated with reduced motivation and weaker performance. Transactional leadership is shown to be effective primarily for structured, well-defined project tasks. The paper concludes with practical recommendations for project managers and directions for future research.
