These enhancements focus on clearer outcome metrics, explicit sustainability and digital leadership, streamlined values with measurable behaviors, and stronger linkage between values and performance.

Embed explicit client outcome KPIs in the mission

Specify measurable client outcomes—e.g., target average TCoR reduction of 10–15%, 20% faster time-to-recovery for cyber incidents, and concrete capital-efficiency improvement targets—to make Marsh McLennan mission commitments measurable and trackable.

Elevate sustainability and digital leadership in the vision

Improvements

• Sharpen outcome metrics in the mission: incorporate explicit client outcome KPIs (e.g., average TCoR reduction 10–15%, capital efficiency improvements, time-to-recovery in cyber events) to mirror best-in-class specificity seen in leading advisory firms.
• Elevate sustainability and digital in the vision: explicitly reference leadership in transition finance, climate resilience modeling, and AI-enabled advisory, aligning with market trends (AI-driven underwriting, parametrics, secondary perils).
