In the project management literature, it is increasingly stressed that the most serious challenge for the project manager is attracting and motivating talented participants with very limited means and instruments of influence. No one ever doubts the need for interpersonal or "soft" skills related to aspects such as leadership, relationships, conflict management, motivation, team building, etc. Recognizing the essential role of "people" in the success of the project leads to identifying leadership skills as more important than planning and control skills, which is essentially related to a transition from the "technical" to the "behavioral" nature of the project or to the purely human side of project management. In this context, this report consistently draws attention to the project manager's leadership, interpersonal management approaches in the team, and tools to motivate participants.
