I quite enjoyed reading Scrum: The Art of Doing Twice the Work in Half the Time. It’s not the book that people are mad at, it’s the shitty implementation of what management thinks scrum is. Because they never read the book.
Thing is that when practically everybody ends up with a shitty implementation of scrum, maybe it is a problem with the methodology after all. At the very least this indicates that it's hard to get right in practice. I've worked on teams with certified scrum masters who went through training courses, and it was still shit.
I think the methodology is fine and it certainly isn’t complex. It’s just difficult to start using it when the corporate culture isn’t able to adapt and change it’s structures, that’s the hard part. Also a topic in the book.
Scrum is "bottom up" and the scrum master doesn’t manage anyone or anything, they are there to serve the team and get rid of obstacles. The team is empowered. If there’s a "manager" for the team, that’s already a mistake. That role doesn’t exist in scrum.
