| Cue | What to remember |
|---|---|
| Readiness | Check identity, licensing, data governance, and admin roles before enabling Copilot broadly. |
| Access | Use groups, role assignments, and policy boundaries to control who can use Copilot and agents. |
| Data governance | Copilot answers depend on reachable data, so permissions and oversharing risk matter. |
| Administration | Know where admin centers, reports, and policy settings fit. |
| Adoption | Plan support, communication, and feedback loops rather than treating Copilot as only a switch. |
