Interesting showcase on how to communicate UX progress within the team, however:
If the project is small (both in number of team members and number of stories) you might be able to get away with rearranging story cards on the wall. However, in my experience, things inevitably get more complex. You often want to consider multiple factors when reviewing the backlog. A UXI Matrix helps you track and view these multiple factors.
(to those who follow @murb: “During release and sprint planning you can sort, group, and filter user stories in Excel” ;) )
