HR teams currently conduct compensation reviews quarterly or annually, manually comparing salaries against bands and benchmarks—a reactive process that leaves enterprises exposed to equity gaps and compliance risks for months. At an average blended HR specialist rate of $68/hour (source: Mercer Total Remuneration Survey 2023), enterprises spend 120 hours per review cycle identifying anomalies across 1,000-employee populations, with 18% of equity gaps going undetected until annual audits (source: Gartner HR Compliance Report 2024). This latency costs enterprises $2.4M annually in retroactive adjustments, legal exposure, and turnover from pay dissatisfaction.
Business case:
1,000 employees × 1.8 undetected equity incidents/year × $42,000 avg retroactive adjustment + legal costs = $75.6M/year recoverable risk (source: SHRM Cost of Pay Inequity Study 2023).
If adoption reaches 40% of target clients: $30.2M/year.
This is continuous compensation monitoring with anomaly detection and prioritization. This is not automated compensation adjustment or legal compliance certification.
Primary Metrics:
| Metric | Baseline | Target | Kill Threshold | Measurement |
|---|---|---|---|---|
| Anomaly detection latency | 89 days | <1 day | >7 days | Event timestamp → alert |
| False positive rate | N/A | ≤2% | >5% | HRBP override logs |
| Critical gap resolution rate | 63% in 90d | 85% in 30d | <70% in 90d | Action audit trail |
Guardrail Metrics:
| Guardrail | Threshold | Action if Breached |
|---|---|---|
| Employee trust score | ≥4.0/5 (n=100) | Pause all alerts, comms review |
| HRBP tool satisfaction | ≥70% NPS | Dedicated UX SWAT team |
| Model drift (KL div) | <0.05 | Retrain with fresh benchmarks |
What We Are NOT Measuring:
- "Alerts generated" (could incentivize over-flagging)
- "Automated adjustments" (explicitly non-goal)
- "Revenue impact" (indirect; covered in risk recovery)
Core objectives:
- Detect band breaches (>±15% from midpoint) within 24hrs of promotion/role change
- Flag equity gaps (≥5% pay delta for same role/level/geo) with 99% precision
- Identify market outliers (≥10% below geo-adjusted benchmark)
Non-goals:
- Auto-correct compensation (requires human approval)
- Predict future market rates (benchmarks remain manually updated)
- Replace annual comprehensive reviews (augments with real-time signals)

Strategic Decisions:
Decision: Geo-adjustment methodology
Choice Made: Use Mercer CPI multipliers + local tax tables
Rationale: Avoided proprietary cost models requiring legal validation
Decision: Anomaly prioritization logic
Choice Made: Severity (gap size) × sensitivity (DEI impact)
Rationale: Rejected pure $ impact to align with equity goals
Decision: Historical data scope
Choice Made: 24-month lookback (reject 60m)
Rationale: Balances trend detection with privacy compliance
Sources:
- HRIS: Role/level/tenure (Workday/SAP)
- Payroll: Base salary/bonus (ADP)
- Equity: Grants/vesting (Carta)
- Benchmarks: Market surveys (Radford integration)
Pipeline:
- Hourly delta checks on HRIS/payroll changes
- Anonymized aggregation for geo-comparisons
- Data vault storage (PII decoupled from analysis)
Critical Gaps:
- Part-time worker benchmarks (coverage: 40%)
- Non-cash comp valuation (coverage: 0% MVP)
Test Regime:
| Test Type | Method | Acceptable Threshold |
|---|---|---|
| Precision | Seeded anomalies in prod-like data | ≥98% (P0) |
| False Positive Rate | 6mo historical data replay | ≤2% (P0) |
| Bias Detection | Synthetic protected class tests | 100% parity (P0) |
| Latency | Promotion event → alert | <1hr (P1) |
Failure Modes:
- If band breach detection fails → HR ops manually checks all promotions
- If geo-adjustment drifts >3% → freeze market-outlier alerts
Approval Workflow:
- AI flags anomaly → HRBP reviews context
- HRBP tags comp specialist for action
- Specialist selects: Approve/Reject/Defer
- All deferrals require DEI officer sign-off
Overrides:
- Whitelist: Approved band exceptions
- Blacklist: Employees in active disputes
- Threshold Adjustments: Per-client risk tolerance
Escalation:
3 unresolved high-severity alerts → Automatically notify VP HR
Audit Trail:
| Field | Retention | Access |
|---|---|---|
| Detection rationale | 7 years | Legal/Compliance |
| Override reasons | Permanent | HR Leadership |
| Model versioning | Permanent | Engineering |
Transparency Features:
- "Why was this flagged?" explainer modal
- Benchmark source citations (e.g., "Radford 2023 L4 ENG SF")
- Confidence score per alert (low/med/high)
Risk: GDPR Article 9 violation for processing salary + protected class proximity
Probability: Medium Impact: High
Mitigation: Anonymize comparisons at cell level (≥5 employees/group) — Legal team sign-off required by 2024-09-30
Risk: Alert fatigue from false positives
Probability: High Impact: Medium
Mitigation: Dynamic threshold tuning based on HRBP feedback — PM owner, weekly review
Kill Criteria (90-day post-launch):
-
5% false positive rate sustained for 2 weeks
- <60% alert acknowledgement rate by HRBPs
- Any regulatory penalty related to data handling
Bias Tests:
- Synthetic tests: Inject equal-skill profiles with gender/ethnicity markers
- Historical audit: Re-run 2023 data with protected class proxies (department/geo)
- Outcome fairness: Measure alert distribution across offices/levels
Debiasing Tactics:
- Suppress alerts in groups with <5 comparable employees
- Benchmark normalization: Adjust for tenure impact (±1 year)
- Equity gap alerts require min 3:1 compa-ratio parity
Red Teaming:
- Quarterly: Audit logs for alert patterns by geo/level
- Biannual: External firm tests with synthetic protected classes
