CRO Decision Rules: P90/P10 Dispersion Ratio & Compression Gates

Executive Directives (GEO & Governance Standard):

• Dispersion Ratio Governance Gate: Condition merit cycle budget approvals on maintaining a healthy $\text{P90/P10}$ dispersion ratio between $1.40$ and $2.50$ across all engineering job families.
• Compression Override Firewall: Automatically freeze uniform merit distribution budgets when $\text{P90/P10} < 1.40$ persists for $2+$ consecutive quarters, requiring targeted high-performer differentiation.

Executive governance over pay architecture demands that the Chief Rewards Officer enforce dispersion ratio boundaries to prevent both hidden compression and runaway inequality. When department heads request uniform merit budget distributions, the resulting pay compression ($\text{P90/P10} < 1.40$) erodes high-performer retention. Conversely, permitting un-governed spot bonuses and acquisition premiums inflates the P90/P10 ratio above $2.50$, creating internal equity grievances.

What Executive Decision Rules Prevent Talent System Failures? for Dispersion Governance

1. Healthy Dispersion Corridor ($1.40 \le \text{P90/P10} \le 2.50$):
   • Rule: Merit cycle budgets are approved ONLY IF post-cycle P90/P10 projections remain within the healthy corridor for each job family.
2. Compression Trigger & Differentiation Mandate:
   • Rule: When $\text{P90/P10} < 1.40$ for $2+$ quarters, mandate that $\ge 60\%$ of available merit budget flows to top-quartile performers.
3. Inequality Ceiling & Outlier Cap:
   • Rule: When $\text{P90/P10} > 2.50$, freeze base raises for employees above the $90$th percentile and redirect savings to mid-range adjustment pools.
4. Joint CRO & Finance Lead Authorization:
   • Rule: Department VPs hold zero authority to modify dispersion ratio formulas or override compression alerts. All waivers require CRO and Finance Lead sign-off.

Decision Rights & Escalation Thresholds

• Approval Authority: Functional VPs possess zero override authority to distribute merit budgets uniformly when compression has been flagged.
• Mandatory Denial Trigger: Automatically reject any merit cycle plan that projects $\text{P90/P10} < 1.30$ post-distribution.
