The risks attendant upon change may have to be weighed against other risks arising from maintaining the same state of affairs. - Tom Burns

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.

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.

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 In particular, nothing in our experience justifies the assumption that mechanistic systems should be superseded by organic in conditions of stability.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.
