I suspect that if I refer to the original creators of the agile manifesto as a club they may go into defense mode. Maybe they could tell us why none of the original members worked for large enterprises, the federal government, large consulting firms and so on. While the work was good, was this in rebellion to something else?
Well, the creation of XP itself happened on the C3 project at Chrysler. Which was (and is), a pretty big enterprise shop. In fact, the C3 project was an attempt to rescue an enterprisey project that was failing.
