Building a team, promoting productive cooperation and a good team spirit are challenges for every manager. It is the responsibility of the manager to select suitable employees, provide orientation and clarify the goals and mission of the team. Overriding customer-related and economic objectives play a major role in this. A good team is created where the skills, knowledge and potential of the employees complement each other effectively and the employees approach the challenges with high motivation. Convincing leadership means that the supervisor provides effective support in achieving goals and acts as a coach and mentor to ensure that everyone can give their best. This includes own credibility, fairness in dealing, respectful action and confidence building.
