Method and formulas
- Price score = lowest price ÷ supplier price × 100
- Lead score = shortest lead ÷ supplier lead × 100
- Quality and reliability scores = rating ÷ 5 × 100
- Total = weighted average of the four scores (weights normalised to 100%)
- A quality or reliability rating of 1–2 excludes the supplier regardless of score
Limitations
- Two suppliers only
- Ratings must be evidence-based
- Uses quoted price, not total landed cost
