Methodology
What the checker tests.
The tool adds the eight entered weights and confirms whether the total equals 100%. It also warns when a single criterion exceeds 40%, because extreme concentration deserves an explicit review. A concentration warning does not mean the model is wrong; some decisions legitimately depend on one dominant requirement.
What it does not test
It does not validate the wording of criteria, normalization formula, score evidence, correlation between criteria, mandatory qualification gates or risk treatment. Those controls require a broader supplier-evaluation design.
Practical review questions
- Would the model produce the intended result if two suppliers have similar prices?
- Are mandatory requirements incorrectly treated as weighted preferences?
- Does cost carry more influence than management actually intends?
- Are two criteria measuring the same underlying issue?
- Is residual risk being scored twice or not at all?
