It's a Crapshoot

"... the process of arriving at business decisions isn't always systematic enough to be supported by computers. You have to take the assumptions out of the mind of the decision-maker and put them explicitly into the process, along with a method to check them, and only then can a computer help you manage it. Older executives find it excruciating to have to be that explicit, because they just don't want to be. Besides, as we all know, many decisions are ultimately made by the hydrostatic pressure in the boss's bladder." Peter Drucker

No shit.
