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. Add to Horizon watchlist with an owner. Pilot only after Steady controls for the affected surface are in place.
12 Panes: 03 Horizon
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.
- Preview or rolling features can change behaviour; fence exploration on Pane 12 Frontier.
