"The effective organization of industrial resources... alters in important respects in conformity with changes in extrinsic factors."

“In mechanistic systems the problems and tasks facing the concern as a whole are broken down into specialisms. Each individual pursues his task as something distinct from the real tasks of the concern as a whole, as if it were the subject of a subcontract. "Somebody at the top" is responsible for seeing to its relevance. The technical methods, duties, and powers attached to each functional role are precisely defined. Interaction within management tends to be vertical, i.e., between superior and subordinate... Management, often visualized as the complex hierarchy which is familiar in organization charts, operates a simple control system, with information flowing up through a succession of filters, and decisions and instructions flowing downwards through a succession of amplifiers.”

“It follows that the more definition is given, the more omniscient the management must be, so that no functions are left whole or partly undischarged, no person is overburdened with undelegated responsibility, or left without the authority to do his job properly.”

“All novelty involves some degree of risk. The vast majority of biological mutations are said to be harmful. When, as in human affairs, enormous numbers of random possibilities are eliminated by rational choice, the chances of harm rather than good resulting are reduced, not eliminated.”

“What is essential is that nothing should inhibit individuals from applying to others for information and advice, or for additional effort. This in turn depends on the ability to suppress differences of status and of technical prestige on occasions of working interaction, and on the absence of barriers to communication founded on functional preserves, privilege, or personal reserve.”

“Organic systems are adapted to unstable conditions, when problems and requirements for action arise which cannot be broken down and distributed among specialist roles within a clearly defined hierarchy. Individuals have to perform their special tasks in the light of their knowledge of the tasks of the firm as a whole. Jobs lose much of their formal definition in terms of methods, duties, and powers, which have to be re¬defined continually by interaction with others participating in a task. Interaction runs laterally as much as vertically. Communication between people of different ranks tends to resemble lateral consultation rather than vertical command. Omniscience can no longer be imputed to the head of the concern.”

“We have endeavored to stress the appropriateness of each system to its own specific set of conditions. Equally, we desire to avoid the suggestion that either system is superior under all circumstances to the other. In particular, nothing in our experience justifies the assumption that mechanistic systems should be superseded by organic in conditions of stability. The beginning of administrative wisdom is the awareness that there is no one optimum type of management system.”
