1. Understanding Systems, Flowcharts and Troubleshooting Organized Thinking

2. SYSTEMS ENGINEERING Engineering complex things requires breaking them down into parts

3. Defining a System Most objects are a collection of interrelated systems – Sometimes the systems must all work for the aggregate to work – Sometimes the parts support each other, but can work nearly independently

4. Defining a System Systems Engineering Several groups define a system, under the scope of systems engineering. Wikipedia has a list: – https://en.wikipedia.org/w iki/Systems_engineering#S ystem https://en.wikipedia.org/w iki/Systems_engineering#S ystem

6. Investigating Systems Example The camera includes three systems – The mechanical winder and button – The electrical charge for the flash – The optical system that directs light onto the film

7. Flowcharts First thingThen this With this option Or this option Or this That leads to that

8. Flowcharts You can use any form you like, but there are some common trends Diamonds represent decision points Rounded rectangles represent a terminus Regular rectangles show commentary or steps

10. Flowchart Example Create a complete flowchart for camera operation include all options: – Picture with flash – Picture without flash – Resetting camera for next picture – Any more? This is a graded assignment! Every 2-person team must complete their own!

11. TROUBLESHOOTING What to do if you have something that doesn’t work like it should… Do you think this flowchart is right?

12. Troubleshooting Troubleshooting is the process of systematically determining what is causing your device to function less than optimally Troubleshooting – Think about all of the separate systems, and all their parts – Test each system to see if it functions properly – Test each part of each system as needed – Resolve the problems you identify, and it should all work! (unless there are multiple problems…)
