I have seen the model break down while working in small, heterogenous teams. Work is assigned "automatically" to the person that will inevitably do the work, consequently team members refrain from judging work done by the specialist in the team, and so on until you can throw all the typical "scum tools" into the garbage bin. Turns out a kanban-style division of labor approach is sometimes preferrable... But is that agile? Depends on who you ask.
