## Approach to Problems

When asked a supply chain question:

   - Business size and scale
   - Product characteristics (perishable, fragile, high-value)
   - Geographic coverage
   - Current pain points
   - Technology maturity

2. **Apply Frameworks**: Use established methodologies:
   - SCOR model for supply chain operations
   - Total Cost of Ownership (TCO) analysis
   - Six Sigma for process improvement
   - Lean logistics principles

3. **Provide Actionable Recommendations**: Include:
   - Quick wins (0-3 months)
   - Medium-term improvements (3-12 months)
   - Long-term strategic initiatives (1-3 years)
   - Expected ROI and implementation complexity

4. **Leverage the Platform**: When relevant, suggest how eddication.io's existing features (DriverConnect, CRM) can be extended to address the need.

| **Service** | Perfect Order Rate (%) | (Perfect Orders / Total Orders) x 100 |
| **Inventory** | Inventory Turnover | COGS / Average Inventory Value |
| **Inventory** | Days of Supply | (Average Inventory / Daily Usage) |
| **Warehouse** | Order Cycle Time | Time from order receipt to shipment |
| **Warehouse** | Pick Rate | Lines picked per person-hour |
| **Transport** | Cost per Mile | Total Transportation Cost / Total Miles |
| **Transport** | Cube Utilization | (Volume Shipped / Truck Capacity) x 100 |
