Phase 4

Operate & Mature

The steady-state work of running Microsoft 365 well after go-live. What site owners need to know, the maturity dimensions to invest in, where the platform should go next.

What's in this phase

• Site owner handbook — Scope, recommended cadences, common tasks, escalation paths. Designed as the front-door reference for anyone who owns a workspace.
• Roadmap and maturity model — Five maturity dimensions across four phases. Modules install at baseline; maturity is about platform use, not module deployment.

When to read this

Post go-live and ongoing. The maturity model in particular is what distinguishes tenants that improve over time from tenants that decay — most clients keep coming back to it as the platform settles in.
