§ The result
Korn Ferry takes the total, Ribbon takes more of the criteria.
Korn Ferry holds a 3-point edge over Ribbon under rubric v1.0, 46 to 43, across the Assessment and Screening cohorts. Ribbon leads more of the criteria, 4 against 3 for Korn Ferry, yet Korn Ferry takes Article 11 Technical Documentation, which carries 20% of the rubric, and the weighted sum with it. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Korn Ferry 58, Ribbon 42 — and at a 20% weight it carries 60% of the weighted advantage Korn Ferry holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +2.8 — the difference between the two totals before either is rounded. Shares are of 7.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +2.8.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
