Closed Loop System
The open and closed loop systems have been used in technology education and engineering classes for decades. Below you will find definitions of all the components of both systems, labeled diagrams, technology study game for the students, a work sheet, and quiz.


System: when multiple items work together to accomplish a task


Open - Loop System: a system that has an Input (Desired Product), a Process (means of producing that product), and an Output (Actual Product) but does not have a method of comparing the Output to the Input


Closed - Loop System: a system that has all the components of an Open - Loop System plus a means of monitoring and comparing the Output (Product) to the Input (Desired product) and making adjustments when needed.


Input : Desired result or product of a system


Process: The part of the system that produces the product using the 7 resources of technology (Capital, Energy, Information, Materials, People, Tool and machines, and time.


Output: the actual product made by the system, it does not have to be tangible


Monitor: part of the closed-loop system that evaluates the output (product)


Compare & Adjust: part of the closed-loop system that compares the output (product) to the Input (desired product and making necessary changes to the process in needed.

Review Questions


1. The part of a closed loop system that analysis the output that will be eventually compared to the input is called what?


2. Which system does not provide feedback that can be used for adjusting the process?


3. An acronym used to remember the 7 resources of Technology is TICTEMP. Write these letters vertically and write out the resource next to the letter. See the example below.
