When developers are the one doing agile-ing, it seems to more successful. When it's a process driven by/for management it can get frozen in place making change harder. Developer driven: Mike: "Bob, I'm skipping scrum today." Bob: "K" (Thinks "He's still working on the gnarly multithreading problem.") Management driven: Manager/Scrum Master: "Bob, where's Mike?" Bob: "He's deep in flow working on that multithreading problem." Manager: "Go get him, he can work on that later." (Thinks "I have boxes to fill in my spreadsheet. How can I do that without a scrum meeting??")
