All groups I've been on have embraced agile practices. Specifically, they have all had a daily stand up and retro. I think this practice adds value to a group, if for no other reason than the power of ritual. It is a daily reminder that we are one team with a common objective.
We have communicated on Slack, scheduled events on team calendars and keep non-project files in a Google Drive. In my latest group, we took the time to really figure out Waffle, which I imagine will become even more valuable as our projects grow in scope and complexity. And, of course, we organize our project with Git.
I feel that good project management is preventative medicine. It fends off problems that poorly managed projects invite.
