4. ObjectiveAgenda  Understand the design process.  Do Now  Notes on The Engineering Design Process  Practice with the Engineering Design Process  Reflection

5.  During the engineering design process you will jump around between steps and not always work in order. This is called iteration.

6.  Ask questions about the problem you observe ◦ What is the problem or need? ◦ Who has the problem or need? ◦ Why is it important to solve?  Who needs what because of why?

7.  Learn from others and research users and customers or existing solutions.

8.  Find the requirements you must follow for your product ◦ How much time do you have? ◦ What size must it be? ◦ Are there any extra things you need to make sure you add?

9.  Try to think of as many solutions to your problem that you can, no matter how outrageous they may be.

10.  Look at all of your solutions and pick the solution that best fits your design requirements.

11.  Keep improving the solution. This will continue through the design process.

12.  This is a model of the final product but is not as polished.

13.  Test your product and make changes  This will continue through the design process  This is the most important step.

14.  Communicate your results to others so that others can repeat what you did.
