Teams are working together using the Slack software. Slack offers chat functionality, organized in different channels, projects, departments, offices, or any other choice. This makes it easy for users to follow the topics that are important to them. Public channels are open to everyone on the team, so marketing can see what designers are working on, sales can see what's on the product team's roadmap, and new hires can be easily notified  instead of starting with a blank email inbox.
