2. **Savings by category** — breakdown by procurement category with methodology used
3. **Savings by type** — cost reduction, cost avoidance, process efficiency, demand reduction
4. **Top 5 initiatives** — largest savings projects with details and validation status

6. **Methodology note** — how savings were calculated and validated
