To manage (verb) a human group is to step through known constraints of a desired future state, match them to commitments from people in the present, and gain agreement to a plan that will meet the constraints by way of the commitments. See back cast to fixed time horizon for more details.

That done, the progress is constantly surveyed and the concerns of participants queried so that there is no silent failure. Avoiding silent failure is the most important duty of managers.

Cleanliness may also be important. According to Spongebob Squarepants:

:"Cleanliness is next to managerliness"

None of this has anything to do with the ability to lead.
