General System Theory
General System Theory accounts for similarities in the functioning of diverse phenomena such as living organisms, machines, galaxy and organizations. All forms, from atomic particles through atoms, molecules, crystals, planets, solar system, and even galaxies may be regarded as 'system'.
'System' may be referred as 'complexes of elements standing in interaction. (Definition by Bertalanffy). The closed system is system that neither takes in nor emits matter. (only energy exchange is taken into account). The system is called an open system if there is continual input and output of both energy and matter in it.
All systems except the smallest have subsystem and all but the largest have supra system, which are their environment. Each system or subsystem have boundary. The boundary of system is the component that separates the system from its environment and filters the inputs to and the output from the system. Inputs, processes, and outputs are all stages in the system's cycle of event.
The open system theory also emphasizes the necessary dependence of any organization upon its environment. The organization imports the input from the environment, and transforms it (through creating new products, processing materials, trains people, provide service) into some other form (with value added) as output in the production process. The output is then exported to the environment. It then becomes input for another system and the cycle and process are repeated.
Education as an Open System
The school system environment is made up of several social, economic, political institutions, which are constantly interacting and are interdependent. A subsystem is a system that exists within a larger system. Examples of subsystems within the school system are Student Council Department, Finance Office, International Office and all other people and things that are the component of the school system. The school internal system will work
