Wish to get the best possible performance from a lazy team? Don't do the tasks they aren't doing.
The worst thing a manager can do is to cover the deficiencies of his team with his own effort, being constantly over them hastening them, giving them precise instructions on how to do each task, and pretending to show your bosses how hard you work.
This leads to a vicious circle, in which you constantly work more and your team performs less.
