I'm honestly surprised to see a post with a vitriol-to-insight ratio so bent in favor of vitriol getting such a positive response. I think the poster here is way, way off mark. It's incredibly frustrating, because so many of the things he says suggest that he or his organizations truly don't understand scrum, yet he proactively goes on the offensive against anyone who suggests he's wrong and won't listen to any evide…
I think the biggest risk to scrum as a methodology is the fact that when it so frequently fails, its defenders constantly fall back on "but that wasn't true scrum". Like, that's 90% of all the posts here defending scrum. Yet the things this guy describes are recognizable to many of us, perhaps it's an extreme case but not that extreme.
the whole structure gives enough support, retros surface problems and give sufficient pushback against "features only, no bugs" management style, sprints gave some sane cadence to both devs and product, daily status checks help to detect folks who are stuck, "refinement" forces both sides to actually commit to some kind of written stuff, and "grooming" provides much needed priorization and black comedy relief as the team tries to come up with a non-pedo expression for the activity.
of course, there are valid criticisms of scrum/agile. mostly that it fails to teach developers to realize their need to set boundaries with regards to interaction with "the client", aaand that most managers and projects are non-ideal, underfunded, and devs should leave it, and look for better ones (even with possibly lower pay).
