When the group comes together for the first time, polite and impersonal interaction is usually maintained. Individuals have high expectations of the department and, the boss, as well as their role and task. At first you can feel a certain euphoria, you want to integrate; you are excited about the new and getting to know each other is in the foreground. That is why I recommend a team building or introductory workshop right at the start. You can find out more about this in my book.
Team coaching is also often referred to as team development and should be implemented steadily and consistently. Because team development is a process of change. It is about a respectful and appreciative cooperation that allows the team to be successful in the long term.
