What is a good mamager?

I was once asked, as part of a management training course, to give my definition of a good manager. I was one of the last ones to give an answer. After a slew of a-dime-a-dozen platitudes (my perception, I agree!) such as "A great leader", "Very skilled in his/her practise domain". "A good listener" I answered simply: "A good manager is home on time. And so are his people"

In other words, don't try to be the hero PM/Leader/CEO
