Are you pointing your groups' storage at SharePoint Online?
What did you do with Yammer?
What are your plans as Teams and Planner arrive?
So too has gone Google Apps with their new Sites rollout and their recent "blessing" of Asana. Sites is still a glorified web-page design tool. Asana continues to lead the pack as one of the best-in-class for task and ad-hoc project management tools. With their new "boards" template, they are after Trello and Basecamp. Todoist's outlook integration is still ahead of the pack. Scribblepost tries a different tack. And of course Slack and Workplace focus on messaging as the core of collaboration although those folks are becoming weary of "having to say something" instead of "having something to say".
