Teams is primarily a collaboration tool. It delivers the greatest benefit when it can bring together, and support coordination of, everyone who has something to contribute to a given goal or topic.

When looking to collaborate on a particular topic, first check to see if a team and channel already exist that you can join.

If nothing exists to meet that need, before creating a team or channel, think about how to create one that will:

• Be findable by others who should be part of the discussion.
• Be a good match for the people in the team. Guest access is not available in Cornell Teams.
• Provide enough privacy to allow open discussion. 
• Support apps or tools you need (Planner and Forms are not yet available in private channels).
• Not contribute to team or channel sprawl or crowding.

More information about benefits and limitations of creating a new team or channel, and a table to help you decide which is the best fit, can be found in Joining and Creating Channels and Teams.
