This is a problem with "agile" and scrum. If the process isn't working for you, it's your fault for not doing it right. And no one is ever doing it right. A truly "agile" team is one that operates in some impossibly perfect Zen-like state that no team achieves in practice.

Maybe it's not you. Maybe it is the process.
