Your question is Improving a Design Cross-Functionally. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you worked with mechanical, electrical, or manufacturing partners to improve a design. What was the tension or constraint, how did you align the group, and what changed in the final design as a result?
