Sample answer
I was tasked with finalizing the enclosure for a new wearable sensor. The design team insisted on a 3‑mm ABS shell for optimal grip and aesthetics, while the manufacturing team warned that the tight tolerances would cause a 15% yield loss and increase tooling costs. I first collected quantitative data: part thickness, material properties, and current tooling constraints. I then facilitated a joint workshop where both teams presented their concerns and constraints. Using a Design for Manufacturability (DFM) checklist, we identified that switching to a 2‑mm polycarbonate shell would maintain ergonomics while improving yield by 5% and reducing tooling cost by 10%. I drafted a revised BOM, updated the CAD models, and scheduled a rapid prototype run to validate the new design. The prototype met all functional and aesthetic requirements, and the final production run achieved a 12% cost reduction and a 20% lead‑time improvement. I documented the process in a post‑mortem report and shared lessons learned with both teams, fostering a culture of data‑driven collaboration.
Key points to mention
- • Stakeholder alignment and data‑driven decision making
- • Use of Design for Manufacturability (DFM) principles
- • Clear communication and documentation of outcomes
Common mistakes to avoid
- ✗ Ignoring manufacturing constraints
- ✗ Overpromising design changes without data
- ✗ Failing to document decisions
