- A system is derived from the Greek word “Systema”, which means an organized relationship between its different components.
- A system is an orderly grouping of interdependent components linked together according to a plan to achieve some specific goal or any tasks.
- Here components may refer to any physical parts like engine, aircraft wings; managerial steps like planning, organizing, controlling, directing, etc.; or a subsystem in a multi-level structure.
- These components may be complex, simple, or advanced.
A system always interacts with the rest or other systems with input and outputs.
The output of one system becomes the input for other systems.
