1 The Universal Systems Model Technology & Engineering Education EHMIS

2 What is it? The Universal Systems Model is a way to describe how a system works The Universal Systems Model is a way to describe how a system works Every Technology, no matter how simple or complex, fits into this descriptive model Every Technology, no matter how simple or complex, fits into this descriptive model

3 What are the parts? Must start with the goal of the system Must start with the goal of the system Input Input Process Process Output Output Feedback Feedback The system can be open or closed loop The system can be open or closed loop

4 InputProcessOutput Feedback Resources: Tools Information People Time Energy Money Materials The steps that lead to a result The result that comes out of the system Positive or Negative Compare the results to the original need; adjustments are made closed-loop system

5 An Example: Skateboarding Goal Goal The goal is to ride the skateboard down the street The goal is to ride the skateboard down the street Input Input Get on the board and kick off Get on the board and kick off Process Process The wheels spin and the board travels down the road The wheels spin and the board travels down the road Output Output The board moves forward and you ride it The board moves forward and you ride it Feedback Feedback All of the information you receive that cause you to make adjustments. (Example: you see a puddle and shift your weight to steer around it) All of the information you receive that cause you to make adjustments. (Example: you see a puddle and shift your weight to steer around it)

6 Closed-Looped vs Open-Looped Open loop Open loop systems have no way of adjusting to changing conditions (closing your eyes riding a skate board) systems have no way of adjusting to changing conditions (closing your eyes riding a skate board) Closed loop Closed loop systems can change under different conditions (eyes open riding a skate board) systems can change under different conditions (eyes open riding a skate board)
