System Loop INPUTPROCESS OUTPUT Systems can be classified into two major groupings – Open Loop System & Closed Loop Systems Open Loop systems are those systems that have to be manually adjusted because they lack automatic feedback. Turning on/off the water faucets at home. Adjusting the speed of an automobile using the foot pedal. Closed loop systems are those systems that can monitor (watch) and adjust themselves without manual feedback.

Input Input is the information, ideas, and activities that we need to provide to determine what we need to accomplish. Can be a command.

Process The part of the system during which something is done. The “action” part of the system.

Output The result of the system’s process.

Monitor/Feedback Information about the output of a system Used to monitor how a system is working Used to make adjustments to the system

Compare and Adjust Compare output to input. Make adjustments as necessary to achieve desired output. Adjustments made by people – Open System Adjustments made automatically – Closed system

Open Systems Systems that have to be constantly adjusted by YOU

Closed Systems Systems that can monitor (watch) and adjust themselves without you being involved.
