Create a reliability matrix: drop, vibe, thermal, humidity, ESD. Define sample sizes, pass/fail, and failure analysis routing between TW lab and US field testers.
Create a pre-cert checklist for consumer electronics: FCC (US), NCC/BSMI (Taiwan), safety (UL-like), and basic EMC pre-scan plan. Include label/packaging marks and doc control.
Define an end-to-end hardware development plan from EVT→DVT→PVT with sample exit criteria, golden samples, and pilot builds. Note lab vs factory responsibilities in Taiwan and US field tests.
Design a split payment stack: US (Stripe/Apple Pay/Google Pay) and Taiwan (local gateways, credit/debit, convenience store pay). Include currency handling and refund flows.
