Supposedly, Henry Ford ran F by eyeballing the height of various stacks of papers on his desk. GM made fun of him for doing so (because they had "scientific management"), but I wouldn't be surprised to find out the numbers on the pieces of paper in each stack were generally for the same order of magnitude, so he really could get actionable "Business Intelligence" by comparing stack heights.
(Are there any other practices on which astrophysicists and Henry Ford could agree?)
