Cost reduction opportunity map: quick wins vs structural

Create a cost reduction opportunity map for {company_name}.

Inputs:
- Current cost base by category: {cost_base}
- Headcount by function: {headcount}
- Contracts and vendor spend: {vendor_spend}
- Facilities footprint: {facilities}
- Constraints (must-keep capabilities): {constraints}

Output:
1) Opportunity table: initiative, category, est. annual savings, one-time costs, time to realize, risks.
2) Quick wins (0–30 days), mid-term (30–90), structural (90+).
3) Implementation owners and dependencies.
4) Measurement plan (how to track realized savings).

Avoid unrealistic assumptions; note what evidence supports sizing.
