Scrum Board with colored post

Often the surface practices such as the daily stand-ups are done. There is a Scrum Board with colored post-its but these are not open to discussion User Stories. There is not really a Product Owner. The team needs to distill the User Stories out of a requirements document or there is already a plan that needs to be build. There is not a meaning of done. The team changes the status of their User Stories to done, when they sense it is done.
