Process

​

1. Design intake → sketches/refs, functional requirements, target FOB

2. Spec pack → drawings, BOM, measurements/tolerances, finishing

3. Proto loop → P1/P2 samples, fit/usage feedback, change log

4. Costing → multi‑vendor quote compare, margin ladder

5. PP ready → sealed sample + manufacturing notes

​
