I find that groups help in a departments ability to solve problems. I like to work s a team, this make all feel like they have a say in the department. If the department is close, have the same agenda and focus, there is more harmony. To facilitate this the leader must be interactive with his employees, and not sit back to see what happens, this will cause more problems then needed. On occasions the leader does need to take an effective lead in tyhe department by setting the goals, guidelines, and due dates, and if problems do arise, beinf flexable to a point shows that you understand that some problems may take time or need to go another dircetion.
