Generators

Many effective leaders I know are powerful generators.  They generate the best thinking of their teams.  They generate high levels of commitment and effort.  They generate enthusiasm in the endeavor.  They generate exemplary performance and service.  How do these folks generate all that powerful synergy?

They're masters at listening and asking questions, 
                                           and listening and asking questions, 
                                                              and listening and...

Questions like:

What things might we stop doing that will improve our service/product?
What ideas could we pilot that might add to our effectiveness?
What opposing points of view or arguments can we expect to hear?

I'm guessing it's rather obvious why those leader-generators are so effective...
