Difference between a "manager" and "boss" is entirely in how they go about getting everyone on the same page. For any given strategic direction, there are a lot of different ways that could be achieved. A good manager takes in information from all her reports (including their preferences, fears, concerns, and goals) and then figures out a plan that keeps all of them happy while also achieving the strategic goals coming down from above. A bad manager takes the goal as the only input and then outputs commands to achieve it.
