System components

A system has five primary components:

  1. Input (machines, manpower, raw materials, money, time, and so on).
  2. Processes (policies, procedures, and operations that convert data into information).
  3. Output (information in the right format, conveyed at the right time and place to the right person).
  4. Feedback (data about the performance of the system).
  5. Control (processing the feedback and taking the necessary action).
