The Copilot readiness page is a useful addition, especially the grouping of deployment essentials, data security, and user experience settings. For organisations that have been hesitant to start, it removes a real barrier. However, a point worth raising for IT admins in the thread: The readiness page tells you where you stand at the moment you check it. What it does not do is tell you when things drift. Permissions oversharing, stale guest accounts, orphaned OneDrive content.
My take away: Treat the readiness page as your deployment checklist, then build a continuous monitoring layer on top of it. File-level visibility and automated alerts are what turn a readiness score into an ongoing posture. Platforms like TeamsFox specialize in these topics and can be useful extensions to the copilot readiness / admin page(s).
