When selecting a material for a product, engineers must consider trade-offs. Which trade-off is most relevant?
Strength vs. cost
Color vs. popularity
Name brand vs. novelty
Weight vs. alphabetic order
Which sequence is the most appropriate generic engineering design process?
Test → Brainstorm → Define → Communicate → Optimize
Define → Brainstorm → Select → Prototype → Test → Iterate

Brainstorm → Define → Test → Prototype → Communicate
To improve maintainability in a design using permanent rivets, one might switch to bolts. The trade-off might be:
Increased assembly speed
Reduced strength or increased cost
Less modularity
Increased weight
