Having cards on the wall is one of the most basic agile practices. Writing index cards or post-its and sticking them on the wall is fun and makes the work place look cool and organized at the same time. What we can't forget, though, is that just having them there doesn't make any team agile. And we can tell something is going wrong...

1. When people work on features that are not on the wall
2. When there are no priorities for the cards
3. When people don't work on the highest priorities first
4. When people work on more than one card at the same time
5. When just one person can tell the current state of a card
6. When people don't have a clear definition of Done
7. When people have to be told what's the next card they should be working on
8. When the wall is not constantly updated
9. When just one person updates the wall
10. When people can't tell how they are doing by simply looking at the wall

These are clear signs that the wall is not being as helpful as it could. And if these issues are not being worked on along the way it may not take long before people start questioning the use of the wall in the first place.
