Criteria and weights
Our own defaults, not from a standard. Change the weights (1 to 3) on the Settings sheet.
| Criterion | Weight | What to look at |
|---|---|---|
| Quality | 3 | Lots sent back, complaints, 8D response |
| Delivery | 3 | Late or short deliveries |
| Response | 2 | Speed and content of answers to problems |
| Documentation | 1 | Certificates, PPAP or FAI files, change notices |
| Commercial | 1 | Price stability, invoicing |
How the band works
The weighted average is the sum of score times weight, divided by the sum of the weights, rounded to one decimal. Our own default cut-offs: 4.0 and above, Keep as is; 3.0 to 3.9, Worth a review talk; below 3.0, worth agreeing an action plan. A row with a missing score shows Fill all five. Under the table, a count of suppliers per band.
Example (fictional)
Made-up suppliers, period ending Wednesday 30 September 2026. Scores in the order quality, delivery, response, documentation, commercial:
| Supplier | Scores | Weighted average | Band |
|---|---|---|---|
| Supplier A | 5, 4, 4, 4, 3 | 4.2 | Keep as is |
| Supplier B | 3, 3, 3, 4, 4 | 3.2 | Worth a review talk |
| Supplier C | 2, 3, 2, 3, 4 | 2.6 | Below: worth agreeing an action plan |
How to use it
- Score from records, such as complaints, delivery data and 8D answers, and note them in the Notes column.
- Share the score with the supplier and agree what changes it. Worth a check: does a low quality score match the open complaints in your supplier 8D tracker?
- For a closer look on site, use the supplier quality audit checklist.
Your own procedure and your customers decide how suppliers are selected and evaluated. The band is an aid for a conversation, not a decision about the supplier.
