HW 3 engineering design

What is the best way to choose a final design?

1. Let each engineer argue for the merits of their design ideas

2. Use the design criteria to compare designs

3. Build prototypes of each design ideas and test them

4. Ask a customer focus group to choose the best design

2

What is the performance score for design 1? how do you calculate it?

183 and you calculate it by multiplying the weight times the results of criteria and adding them all together

Design 2 performance score?

181

Design 3 performance score?

170

If design 1 has the highest performance score does that mean it was the best design or the worst design?

The best because it is closer to the weight of the criteria

What are the steps for engineering design process

1. Identify the need

2. Research the need

3. Reframe the problem

4. Develop possible solutions

5. Select the best solution

6. Construct a prototype

7. Test and evaluate

8. Redesign

9. Communicate the results

What are the three different decision making “tools”

1. The Pugh matrix

2. The decision matrix

3. The risk- informed decision matrix
