By far the most respected of all the management gurus is the redoubtable Peter Drucker. Drucker, moreover, as a central European (northern) émigré to America (western) has strong, rationally based credentials. He has perhaps done more to advance the cause of management, as an administrative and as a social science, than anyone else this century. However, Drucker lacks a coherent theory of management and organization. In fact, his concept of management seems to have been forever changing over the course of the fifty years during which he has been writing. In fact, the management theorist who has the most consistently rationally based theory of ‘requisite organization’1 is the French Canadian Elliot Jaques.
