Planner

Teams channels can be confusing when you don’t have a plan in place for organizing them. Teams chats can get noisy when you don’t define the purpose of each group chat. Planner can be lacking when people don’t assign tasks properly. Loop and OneNote can become absolute chaos when there isn’t a process for note-taking and storage. As Mirko points out, SharePoint can become a junk drawer when things don’t have a defined location that everyone agrees upon. 

That’s not a technology problem. That’s a human problem.
