In the team we are used to be Agile, and especially what I call being Agile doing Agile stuff. Which means being not dogmatic: stop doing a practice when it does not give us enough value and starting it again when we feel that we are missing it. Not only: we also try always to introduce something new. Since the beginning of the project we had 2 swim lanes on the wall, one for actions  to do and one for actions done, we just added a third column, the keep doing actions, it's like having a star fish always there. The waste bin. Yeah, we are interested in what's going on with lean, so now there's a box on the wall, if someone in the team feels that is wasting (s)he can put a card there, we'll discuss it during the retrospective. As a reminder, the seven lean waste types:

1. Overproduction = Extra Features
2. Inventory = Requirements
3. Extra Processing Steps = Extra Steps
4. Motion = Finding Information
5. Defects = Defects Not Caught by Tests
6. Waiting = Waiting, Including Customers
7. Transportation = Handoffs
