The OSTO System Model is based on the OSTO System Theory, which comprehends complex systems and organizations as living systems and maps these by means of the OSTO System Model. The model is cybernetic in nature and is deduced from the theory of closed loops. The basics of this theory have been formulated by David P. Hanna in the 1980s and have been published initially in 1988. The model assumes that several central transformation processes take place on the inside of a complex organization. These are deeply influenced by mutual reactions between the inner life of the organization and the outside (environment). In terms of closed loop theory, the OSTO System Model depicts the essential elements of such a living system in its interconnectedness, dependencies, and reciprocal reactions. Think
