Three-Dimensional Supplier Evaluation Matrix
Create dedicated worksheets tracking these core metrics for each Tiffany supplier:
- Price evolution graphs
- Delivery time breakdowns by jewelry category (rings vs necklaces)
- After-sale service response time logs
- Authentication document verification status
Pro Tip:
Use conditional formatting to highlight suppliers offering serial numbers that match Tiffany's certification database for enhanced provenance verification.
Strategic Partner Selection Algorithm
Implement these spreadsheet formulas to calculate each channel's business value score:
| Metric | Weight | Calculation Method |

| Recent Service Rating | 30% | Positive Review Count ÷ (Total Orders × Species Factor) |
| Certification Compliance | 20% | Number of BVCA Certified Pieces ÷ Total Items Purchased |
