The Human Behavior School: This approach to the analysis of management is based on the central thesis that, since managing involves getting things done with and through people, the study of management must be centered on interpersonal relations. Variously called the "human relations," "leadership," or "behavioral sciences" approach... This school concentrates on the "people" part of management and rests on the principle that, where people work together as groups in order to accomplish objectives, "people should understand people."
