Set up and use Microsoft Teams Advisor
Advisor for Teams walks you through your Microsoft Teams rollout. It assesses your Office 365 tenant environment and identifies the most common configurations that you may need to update or modify before you can successfully roll out Teams.
Then, Advisor for Teams creates a Service management team (in Teams), with channels for each workload you want to roll out. Each workload in the Service management team comes with a comprehensive Planner plan that includes all the rollout tasks for each workload.
Using this Planner plan, you'll assign tasks to the people responsible for each phase of the rollout - including the project manager, Teams and Office 365 admins, support people, and your adoption and user readiness team. Each rollout task contains all the guidance and resources you need to successfully complete the task.
