The fields below contain example values. Replace them with your own evidence; nothing is sent to a Ninth Post server.
How this tool works
Each vendor's weighted score is quality × 0.30 + security × 0.25 + privacy × 0.20 + cost × 0.15 + portability × 0.10, expressed on a 100-point scale. An evidence-gap penalty (0, 5 or 12 points) applies when evidence is weaker than testing on the buyer's own tasks. The tool shows the scores and the underlying dimensions rather than treating the highest score as an automatic procurement decision.
Limitations and responsible use
All vendor names, ratings and evidence classifications are user-entered illustrations; Ninth Post has not tested the named vendors through this page. Security/privacy failures that violate mandatory procurement requirements should be vetoes regardless of overall score. Confirm contractual obligations with qualified reviewers.
