Explains Engineer’s Design Process and Appropriate Technology

3. What is the engineering design process?
It is an approach to solving problems involving a series of steps.

4. Did Shawn’s team follow the steps in order?
No, Shawn used the design process as a guideline, rather than as a rule.

5. What’s the difference between criteria and constraints?
Criteria are desired features.
Constraints are limitations in developing or using the technology, such as costs, time, and materials.

6. How many prototypes did the team build? How many were successful?
Three.
Only one met their criteria for success.

7. Was Shawn surprised with the result
Was Shawn surprised with the result? What do engineers think about failure?
No, he was not surprised.
In the eyes of an engineer, failure provides new and valuable information.

8. Why is communicating the solution an important?
If a new technology is not communicated, no one will know about it.
