A team is a group of people gathered to get something big done in your organization. Sometimes it’s your whole organization.
Teams are made up of channels, which are the conversations you have with your teammates. Each channel is dedicated to a specific topic, department, or project.
For example, the Mark 8 Project team has General, Design, Digital Assets Web, Go to Market Plan, and Research and Development channels. All the conversations, meetings, files, and apps in the Design channel have to do with design, and everything in this channel is visible to everyone on the Mark 8 Project team.
While channel conversations are public, chats are just between you and someone else (or a group of people). Think of them like instant messages in Skype for Business or other messaging apps.
