"To the student of business structure the organization chart is what the anatomical chart is to the student of the human body. It is a device by means of which relations of the different parts of the organization can be brought out more clearly than by a verbal description. The student of business derives from them the same sort of aid that the student of medicine does from the anatomical chart, which enables him to visualize the organs of the human body. While the analogy is helpful, it is like every other analogy, in being only partial."
