Fairness Monitor

Software componentObservability & EvaluationObservability & Evaluationarc:FairnessMonitor

A production monitoring component that continuously computes fairness metrics (demographic parity, equalized odds, calibration) on live predictions, aggregated daily, weekly or monthly, to detect fairness degradation.

Responsibility. Tracks production fairness metrics against thresholds to detect fairness drift.

Also known as: Continuous fairness monitoring, Fairness drift monitor, Continuous bias monitoring

Design guidance

MUST continue after deployment; development-time fairness tests do not guarantee production fairness.
SHOULD compute the same fairness metrics used in development, on live production predictions.
SHOULD trigger root-cause analysis distinguishing data drift, model drift, and environmental change when thresholds are breached.
SHOULD track disaggregated error, approval and outcome-quality metrics across demographic groups throughout the lifecycle, not only at deployment.
SHOULD trigger human investigation of significant disparities to separate legitimate risk factors from proxy discrimination.

Quantitative guidance

As stated by the sources; verify before use.

Example: FPR disparity widening from 1 to 5 percentage points after three months triggers escalation (Ch9.4).
Example: demographic parity gap degrading from 2 to 7 percentage points after three months triggers alerts (Ch9.4).
