How is the total calculated?

For each criterion:

Weighted contribution = criterion weight × rating ÷ 5
Total score = sum of the ten weighted contributions

The maximum is 100. Keep one decimal place if useful and retain the unrounded values for audit. Never assign an unverified capability a neutral midpoint; under this framework it starts at zero.

Illustrative arithmetic only: if a candidate receives 3 out of 5 on a criterion weighted 20, it contributes 12 points. That is an explanation of the calculation, not a rating of a real supplier.

If a criterion is genuinely irrelevant, agree a revised weighting scheme whose total remains 100 before scoring all candidates. Do not remove a weak criterion for only one supplier.
