Algo Hr Compensation

Phase 1: Input Validation

Collect: internal compensation data (base, bonus, equity), market survey data (P25, P50, P75 by role), job matching between internal roles and survey benchmarks. Gate: Jobs properly matched, survey data current (< 18 months).

Phase 2: Core Algorithm

1. Match internal jobs to market benchmarks by content, level, and scope
2. Age survey data to current date: apply projected market movement rate
3. Compute compa-ratio per employee: actual base / market P50
4. Compute percentile positioning: where does actual pay fall in market distribution
5. Analyze: by department, level, tenure, demographics for equity gaps

Phase 3: Verification

Check: compa-ratios cluster around 0.85-1.15 (normal range). Flag outliers (< 0.80 underpaid, > 1.20 overpaid). Test demographic equity. Gate: Distribution reasonable, equity analysis completed.

Phase 4: Output

Return benchmarking results with band recommendations.

Examples

Sample I/O

Input: 50 engineers, market P50=NT$1.8M, actual range NT$1.5M-2.1M Expected: Avg compa-ratio ~0.97, some below-band employees flagged for adjustment.

Edge Cases

Gotchas

• Total compensation: Base salary benchmarking alone misses equity, bonuses, and benefits. Compare total comp for accurate positioning.
• Survey data lag: Published surveys reflect data collected 6-18 months ago. In fast-moving markets, age the data forward.
• Internal equity vs external competitiveness: Aligning with market may create internal inequities (new hire paid more than tenured employee). Balance both.
• Geographic differentials: Remote work complicates location-based pay. Define a clear policy: pay by HQ location, employee location, or hybrid.
• Pay equity legal risk: Unexplained demographic pay gaps expose legal liability. Conduct regression-based equity analysis controlling for legitimate factors (experience, performance, level).
