There are two types of Groups in the Coaching Dashboard:

1) Team.  In the common sense, folks who work together, AND for whom it is appropriate to see Team Insights, and Relationship Insights. Typically for intact teams the best practice is to add a Team on the Invitation Wizard, unless you’re absolutely certain you don’t want Team Insights, and Relationship Insights, which is a rare case.

2) Administrative Group.  Invisible to the learner, but very helpful for the Administrator and Coach, as it makes it simple to add Lenses, Coaches, etc. in bulk to the entire group at once.
