Scoring Rules and Variance Calculations
Quantity Scoring
| Variance Percentage | Score | Example |
|---|---|---|
| 0% (Perfect Match) | 100 | Ordered: 100, Delivered: 100 |
| -10% (Under-delivery) | 65 | Ordered: 10, Delivered: 9 |
| -50% (Significant Under-delivery) | 70 | Ordered: 20, Delivered: 10 |
| +5% (Over-delivery) | 95 | Ordered: 100, Delivered: 105 |
The system calculates quantity variance as: (Delivered Quantity - Ordered Quantity) / Ordered Quantity * 100
Time Scoring
| Delivery Status | Score | Example |
|---|---|---|
| On Time | 100 | Delivered exactly on the requested delivery date |
| 1-2 Days Late | 90 | Delivered 1-2 days after the requested delivery date |
| 3-5 Days Late | 70 | Delivered 3-5 days after the requested delivery date |
| >5 Days Late | 50 | Delivered more than 5 days after the requested delivery date |
| Early Delivery | 95 | Delivered before the requested delivery date |
The system calculates time variance based on the difference between the requested delivery date and the actual delivery date.
Price Scoring
| Price Variance Percentage | Score | Example |
|---|---|---|
| 0% (Perfect Match) | 100 | PO Price: $100, Invoice Price: $100 |
| +1% to +3% (Small Overcharge) | 90 | PO Price: $100, Invoice Price: $102 |
| +3% to +5% (Moderate Overcharge) | 70 | PO Price: $100, Invoice Price: $104 |
| >+5% (Significant Overcharge) | 50 | PO Price: $100, Invoice Price: $106 |
| Negative Variance (Lower Invoice Price) | 100 | PO Price: $100, Invoice Price: $98 |
The system calculates price variance as: (Invoice Price - PO Price) / PO Price * 100
