What is the most important quality of a good Manager?

hi warren I think the most important quality of a manager is the ability to attract and keep good employees who enjoy their work.
Only when employees enjoy their work and are proud to be in the team work will be done nicely and efficiently.
Its important that a manager sees the person as is and not only some technical aspect of how much output that person has given or not given in a day.
We are no robots and machines but people and should be treated as such, everyone can and will have a bad day here and there or come to work though he or she is sick and doesnt want to take sick leave at once and then this person who does this should be helped or encouraged and thanked for not just turning in a fake sick leave paper instead. Just one area where you can tell a good from a lousy manager.

A good manager should know his employees so well that he does not overburden them nor let them sit lazy.

I think, the most important quality of the manager is to organize, empower, and lead the team towards the completion goals. That's it: the good manager should be a good leader. The meanings of these words are different, and ocassionally cotraversial. But combibnation of management and leadership skills brings the vistory.
