To track a project in the Weekly Priorities or Level 10™ Dashboard, first navigate to the dashboard under Team Alignment. Then, using the view toolbar, click the second button to access the GSD ('Get Stuff Done') view.
Click the compass icon to open your sidebar organizer. Make sure that ADD is toggled - this way, the items you bring into the dashboard show both in the dashboard and in the project it was in originally.
Click the PROJECTS tab, drill into the project you want to track, and drill in further if there are columns or subsections. Then, simply drag and drop relevant items to the appropriate column.
