Systems Model

Universal Systems Model


A systems model involves a combination of elements or parts to complete a task. When the parts of a system work together, they accomplish a goal. A universal model of a system is presented in the illustration below.

Systems Model3
The “inputs” to the system provide all the needed resources to accomplish the goals of the system. The “processes” are the action which brings about system goals using the inputs (resources). The “outputs” of the system include the ends or goals (products, services, and/or societal impacts).


System Inputs


The “inputs” to the system provide all needed resources to accomplish the goals of the system. Six general inputs to technology education systems are 1) people, 2) knowledge, 3) materials, 4) energy, 5) fixed capital-land, buildings, tools, and equipment and 6) money. 


System Processes


The “processes” area of the system is where action takes place to achieve the goals of the system. Knowledge of the processes and how to perform processes is called technology.


System Outputs


The “output” of a system if the goal to which all of the inputs and processes are applied. These may be products, services, new knowledge, and impacts of the system on society.




Information can be transferred back to any position in the system for evaluation to see if things are going as planned. Corrections can be made in inputs and processes to alter the outputs from the system.
