When going to the Team Scheduling area you will notice a calendar view for your team and projects, where you're able to view and add new bookings. A booking is a particular time when the user should work on an assigned task. This helps your team focus on specific tasks and know how much time they should spend on them.
For project managers and admins it also means they can follow how busy their team is, if they're getting too crowded or if they can still be assigned more tasks.
Bookings can be viewed or created by Users or Projects, depending on the view you're in.
Each booking has its own unique booking ID which you can share
