Early on in the movement, one of the big names who also had some fairly close corporate associations came to speak at a user group meeting hosted at my then BigCo location. I even passed news of the event around so that interested parties in our local shop could head down after hours and have a listen.
I felt rather bad afterwards for having done so. One of the more useless talks I've attended. Very superficially prescriptive (you should do X; Y has seen benefit Z), with no meat to the description (or prescription, as it were).
Agile may well have its place. But its intersection with BigCo life, as anecdotally exemplified in this fellow, seemed to be just more of the "same old same old". New words, same shit.
