Agile is cargo cult. Customers are not agile to your fuckups. Competitors are not agile to your "scope creep". You know what is the current most agile company in software? Microsoft. You know why? Because no matter how much it fucked up its business is so huge and so vast that it did not matter. It makes money. But even Microsoft is starting to feel the need to deliver as otherwise it is going to become IBM or Xerox.
