Why you should care

Board

Track as Horizon signal; decide whether it changes Wave 0 priority or stays on the watchlist.

CISO

Confirm identity, data access, and overshare exposure before enabling for broad cohorts.

CFO

Map licence or consumption impact to the frozen value case; avoid seat spray.

Adoption

Pilot with a named cohort and measure changed work, not vanity clicks.

Suggested action

Wave 0 first: Security → GRC → Cost & Value → Licence → Adoption. Decide: adopt for a named cohort, defer, or reject. If adopting, update licence and adoption plans in the same week.

Communication needed

  • Security: Assess exposure, Conditional Access, and agent/tool permissions.
  • GRC: Update AI/agent register and evidence path; confirm DPIA triggers if personal data is in scope.
  • FinOps: Forecast seat or credit impact; align to frozen value case.
  • Adoption: Plan cohort messaging, clinics, and success measures.
  • Comms: One story for board and staff — what changes, what does not, who owns risk.

Benefits

  • May improve productivity on a specific Microsoft 365 surface when permissions and data quality allow.
  • Roadmap visibility helps Horizon planning without guessing dates.

Risks

  • Status and dates change; treat MRC as directional, not a contract.
  • Enabling without Steady controls can amplify overshare or cost leakage.
