Viable System Model

Theoretical framework of management cybernetics: The viable system model (VSM) is a model of the organizational structure of any autonomous system capable of producing itself. It is an implementation of viable system theory. At the biological level, this model is correspondent to autopoiesis. A viable system is any system organized in such a way as to meet the demands of surviving in the changing environment. One of the prime features of systems that survive is that they are adaptable. The VSM expresses a model for a viable system, which is an abstracted cybernetic (regulation theory) description that is claimed to be applicable to any organization that is a viable system and capable of autonomy. https://en.wikipedia.org/wiki/Viable_system_model

• The model was developed by operations research theorist and cybernetician Stafford Beer in his book Brain of the Firm (1972). Together with Beer's earlier works on cybernetics applied to management, this book effectively founded management cybernetics.
• The first thing to note about the cybernetic theory of organizations encapsulated in the VSM is that viable systems are recursive; viable systems contain viable systems that can be modeled using an identical cybernetic description as the higher (and lower) level systems in the containment hierarchy (Beer expresses this property of viable systems as cybernetic isomorphism).
