"The open system approach to organizations is contrasted with common-sense approaches, which tend to accept popular names and stereotypes as basic organizational properties and to identify the purpose of an organization in terms of the goals of its founders and leaders. The open system approach, on the other hand, begins by identifying and mapping the repeated cycles of input, transformation, output, and renewed input which comprise the organizational pattern. This approach to organizations represents the adaptation of work in biology and in the physical sciences by von Bertalanffy and others."
