I don't think that this is true in all pursuits. I was arguing
the other day with a friend of mine who was complaining that
his choir director was a lousy singer -- and therefore could not
be a good vocal conductor.

I pointed out that the maestro of the orchestra doesn't need to
be able to play all of the instruments to be a good conductor.

True, but bad engineers invariably make bad engineering managers.

It's sort of like the pilot/instructor thing. A good pilot can be a
poor flight instructor, but a bad pilot is always a flight instructor.

You can't manage it (or teach it) if you can't do it.
