## Notes

- Items are ordered by priority, not by required sequence
- Dependencies are clearly marked (e.g., Item 2 depends on Item 1)
- Each item has a "why" (source from FMEA/TRIZ/Andon/Gemba)
- Estimated effort is for implementation only (design already complete)
- Items can be parallelized where no dependencies exist
- Success criteria enable objective completion verification
