Systemic Management Artur Victoria The word cybernetics comes from the Greek (kybernytiky) and is related to the activity of governing, conducting ships. Hence, cybernetics is the science of communication and control, whether in the animal (man, living beings) or in the machine. It is communication that makes it possible to make systems integrated and coherent, and control is what regulates their behaviour. Cybernetics understands the processes and systems of information transformation and its implementation in physical, physiological, psychological, etc. processes of information processing. Cybernetics is a theory of control systems based on communication (transfer of information) between the system and the environment and within the system, and the control (feedback) of the systems function with respect to the environment. Cybernetics Field of study The field of study of Cybernetics are the systems as being any set of elements that are dynamically related to each other, forming an activity to achieve a goal, operating on inputs, (information, energy and matter) and providing outputs (information, energy or matter) processed. The elements, the relationships between them and the objectives (or purposes) constitute the fundamental aspects of the definition of a system. The input of a system is what the system imports or receives from its outside world. Inputs comprise the physical and abstract elements or resources of which the system is made, including the influences and resources received from the environment, thus we can cite that the entries can be constituted of Information, Energy and Materials. Outputs can be defined as the end result of the operation or processing of a system. Every system produces one or more outputs. Through the output, the system exports the result of its operations to the environment. The concept of black box, refers to a system whose interior cannot be unravelled, whose internal elements are unknown and can only be known "externally" through external manipulation or external observation. The concept of a black box is used in two circumstances: A. when the system is impenetrable or inaccessible; B. when the system is excessively complex, difficult to explain or detail
