How long do we think it will be before a lot of the recent negative sentiment about Scrum bubbles up to exec-level consciousness? I've seen (and managed) plenty of Scrum, good and bad. In general I prefer Kanban approaches, but I don't think it's the deciding factor in team performance by itself. I'm interested to see when we reach the point where it's no longer the default methodology everyone reaches for because "Scrum is how you do agile".
