Abstract: the article deals with the issue of project team management in the context of role interaction between project participants. The right choice of participants in the project team determines better results in the implementation of the project. When forming a project team, it is important to take into account the personal characteristics of participants, dominant roles, and a tendency to a particular style of leadership. The authors of the article conducted a study of the relationship between role interaction and leadership style of project team members, which was attended by 62 participants of project teams in educational and event organizations. The results of the study revealed positive correlations between the transformational leadership style and such team roles as “shaper” and “expert”, between the transactional leadership style and the team role of “coordinator”. A negative relationship was found between the transactional leadership style and the team role of “collectivist’. With the dominant role of the “collectivist”, the transactional style of leadership is less expressed. Additionally, the relationship between leadership styles and managemet styles is confirmed. The empirical data obtained indicate similar characteristics of collegial leadership style and transformational leadership, and directive leadership style with transactional leadership. The main conclusions of the study can be used by managers of organizations when forming project teams.
