What this is

The Leadership Index is a composed Product that scores leaders on predictive acuity (how well their judgments forecast outcomes) plus three-way directional alignment (up, down, and lateral). It turns dispersed rater and forecast signals into one comparable leadership measure. Built on the manager-effectiveness spoke (1.2.0).

What it composes

• Rater + directional alignment (performance-validity) — up/down/lateral agreement.
• Interval calibration + Bayesian source-combination (forecasting) — predictive acuity from calibrated judgments.
• Manager-effectiveness scoring across domains, keyed by tenant × employee × cycle.

Surfaces

• Spoke: manager-effectiveness (/api/spokes/manager-effectiveness/*, MCP manager-effectiveness.*). See the generated reference for exact methods.

Who it's for

Heads of People Analytics and senior HR leaders building a defensible, longitudinal view of leadership quality — beyond engagement surveys or single-source ratings.

Honest scope

A measure, not a verdict. Scores depend on rater coverage and forecast history; the Index informs leadership decisions, it does not make them, and it is not a substitute for managerial judgment.
