Teamwork itself is a concept of cooperation and work jointly undertaken by a group of employees. The key to a successful project is in the people who take part in the work on the project.It is important to approach all participants from the perspective of their own potential. The job of the project manager is to recognize the skills and abilities that each of the participants has at their disposal, encourage and motivate them to further improve and develop so that the project can end up being as successful as possible. It is very important that the project manager communicates well with the project team, listens to their needs and thus stimulates their motivation, that he praises and rewards successes and achievements of the entire project team or individual members. Assigning roles is of great significance for the project, it makes the level of authority and responsibility of each team member clear so that the members know exactly who should participate in which activity and help avoid potential conflicts or problems in communication within the project team.The goals of teamwork must be clear to all and predefined, and all tasks and roles of individuals in the team clearly defined and assigned.
