An organization, a social artifact, is very different from a biological organism. Yet it stands under the law that governs the structure and size of animals and plants: The surface goes up with the square of the radius, but the mass grows with the cube. The larger the animal becomes, the more resources have to be devoted to the mass and to the internal tasks, to circulation and information, to the nervous system, and so on.

Peter Drucker, The Effective Executive, 1967.
