The Project Management Professional (PMP) emphasizes the importance of leadership styles in project management. It suggests that a project manager should be able to move from one leadership style to another depending on the situation, which is crucial to be extraordinarily effective1. Moreover, the Professional in Business Analysis (PMI-PBA) highlights the role of a project manager in engaging and motivating the team towards a shared vision to achieve together2. Therefore, studying and determining the appropriate leadership style is essential for improving team performance and commitment. References: * Project Management Institute. (2011).
