That's it, the marketing people take a very simple concept, put a lot of marketing bullshit around it, make it seem A LOT MORE difficult than it needs to be and you then have to take a million courses to understand what the hell is going on. The best "agile" managers I have worked with "just got it", just like the best developers. There is none of this spoon feeding a baby crap.
I don't really have a problem with the tenets of Agile, but the Church of Agile, its high priests, and its associated industries are bullshit.
