Ask HN: Does Scrum work?

I’ve read the Michael O. Church article and quite a bit of other stuff about how bad Scrum and the like are, and I’m trying to find some counterpoint info. Unfortunately, most of what I find when searchig for information on the other side of the coin is from firms trying to sell scrum certifications and training. Are there any devs out there working in a scurm shop who think their team is actually successful because of scrum? Does this actually work from the Devs/Engineer’s perspective or is it as much of a scam/fad that it seems?
