I think the argument for scrum is something like "Our big organization has complicated politics and scrum is one way of dealing with those politics." However, I often wish the management would directly address the internal politics that undermine productivity. I realize that it is awkward and uncomfortable for managers to talk honestly about the differences they have with other managers and other teams, but that is also their profession. That is, working through any relationship that undermines productivity is the job of a manager.

I wrote about this here: "The Agile process of software development is often perverted by sick politics"
