If you have a lot of projects it can be tricky to keep track of them all. One tool which should help with this is Divisions.
If you are an Organisation Administrator, then from within the Organisation Settings, you can create and manage Divisions.
Outcome maps can then be assigned to divisions from within the project settings.
Any outcome map which has not been assigned to a division will appear at the top of the organisation home.
When managing multiple child projects, Divisions can help you to separate them in a more organised fashion.
