Methodologygovernance-index-v1

How the governance index is scored.

A weighted, eight-dimension score measuring an organization's AI governance maturity across inventory, regulatory controls, policy enforcement, detection, remediation, and evidence readiness. Scale 0–100.

Overview

How the score is computed

The governance index is a composite score derived from eight weighted dimensions. Each dimension is computed independently and scores stay within the 0-100 range. The final score is the weighted sum of all dimension scores, rounded to the nearest integer.

score = Σ (dimension_score_i × weight_i) where each dimension_score_i ∈ [0, 100]

Scores update quarterly (Jan, Apr, Jul, Oct) and on event-driven triggers (control status changes, finding triage, policy updates). Each snapshot pins the methodology version and all inputs for replay.

Dimensions

Components and weights

Dimension Weight What is measured
Inventory completeness 15% Percentage of owned systems, systems with a recorded status, and resolved shadow AI discoveries. Average of the three ratios.
Risk assessment coverage 15% Percentage of systems with a risk score and a recorded autonomy tier. Freshness of most recent assessment factored in.
Regulatory and control coverage 20% Percentage of mapped controls that are implemented, evidenced, and assessed. Highest weight, reflects direct regulatory alignment.
Policy enforcement maturity 15% Active policy ratio, lifecycle event activity, sector pack adoption, and rollback pressure penalty.
Detection and monitoring coverage 10% Starts at 100, then subtracts severity-weighted penalties for open severe findings (−12 each) and unprocessed governance events (−2 each). Floored at 25 when findings data is present.
Review and remediation discipline 10% Resolved-finding rate, closed workflow task rate, and penalty for overdue tasks (−10 per overdue item).
Evidence and audit readiness 10% Percentage of controls with attached evidence, presence of an audit log trail (contributes 80 points), and presence of a governance event trail (contributes 70 points).
Change management 5% Processed-event rate, audit log presence (80 points), and rollback pressure penalty (−15 per rollback).
Computation details

Normalization and clamping

Each dimension score is clamped to [0, 100] before weighting. No dimension can drag the composite below zero or above the cap defined by its weight alone. The formula for the highest-weight dimension (regulatory and control coverage) at 20% weight can contribute at most 20 points to the composite.

dimension_score = clamp(raw_score, 0, 100) composite_score = round(Σ dimension_score_i × weight_i)

Detection and monitoring is the only dimension with a floor condition: if finding data exists for the organization, the dimension score is floored at 25 (not 0) to prevent a zero score from masking the presence of a detection surface.

Confidence levels

The score carries a confidence label based on data completeness:

Event triggers

When scores recompute

Q

Quarterly refresh

Scores recompute on the first of January, April, July, and October. Ensures boardroom-cadence freshness even when no governance events fire.

E

Event-driven triggers

Recompute fires on control status changes, finding triage transitions, policy lifecycle events, shadow AI registration or dismissal, and risk score updates.

S

Snapshot pinning

Each recompute produces an immutable snapshot: methodology version (governance-index-v1), all dimension inputs, computed weights, and final score. Snapshots are replayable.
