The topic of the final work is teamwork in project management. The aim of the paper is to explain what teamwork is, explaining its importance in project management. When managing a project, teamwork achieves very important goals because projects need to be completed on time and in full. Each team member has a role to play and tasks that need to be successfully accomplished with good collaboration among team members. A good team in project management contributes to a healthy work environment. Good teamwork can contribute to savings, more successful project results and ultimately higher profits. It also contributes to the quality and individuality of the project. The example of a project implemented by the city of Split shows that the project service has 20 team members. When creating projects, it is not necessary for everyone to participate, but each project has its own leader, and if it is a larger project, then two project leaders can be appointed. The above example shows how the project was successfully implemented and how new projects are being developed.
