That said, an entire industry has emerged to sell this methodology, and it is supporting a vast array of jobs: everything from those selling the certifications, to the software used to track developers. There are too many vested interests now, and no company wants to admit that it burned through thousands of dollars, with dubious results, to "train" managers and subscribe to the usual software bundles.
I expect the comments here will also have the usual comments about how Scrum is great, and everyone who is critical of it is just doing it wrong.
