§ The result
Korn Ferry takes the total, Workstream takes more of the criteria.
Under rubric v1.0, Korn Ferry, filed under Assessment, finishes on 46 and Workstream, filed under Screening, on 39, 7 points apart. Workstream leads more of the criteria, 4 against 3 for Korn Ferry, yet Korn Ferry takes Bias Audit Transparency, which carries 18% of the rubric, and the weighted sum with it. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Korn Ferry 48, Workstream 20 — and at an 18% weight it carries 54% of the weighted advantage Korn Ferry holds across the 3 criteria on that side of the table.

Shares are of 11.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +7 beside that +7.4.

§ 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.
