In any hierarchy, each individual rises to his own level of incompetence, and then remains there. There's never time to do it right, but there's always time to do it over. When in doubt, mumble. When in trouble, delegate. Anything good in life is either illegal, immoral or fattening.
Nature always sides with the hidden flaw.
In case of doubt, make it sound convincing. Never argue with a fool, people might not know the difference.
