§ The result
Plum leads Korn Ferry on 5 of the 7 criteria.
Plum scores 54 and Korn Ferry 46 under rubric v1.0 — an 8-point gap inside the Assessment cohort. Plum leads 5 of the 7 criteria and the remaining 2 are level, so Korn Ferry is ahead on none of them; the closest of the 5 Plum leads is Data Governance Disclosure, Korn Ferry 52 to Plum 54. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Korn Ferry 48, Plum 83 — and at an 18% weight it carries 76% of the weighted advantage Plum holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to -8.3 — the difference between the two totals before either is rounded. Shares are of 8.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -8 beside that -8.3.

§ 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.
