I'd be interested to hear about (1) that scrum failure in the 10's of millions of dollars, and (2) what you prefer instead of Agile.

(I'm a developer on a scrum team and really think it helps us, but I'm not dogmatic about it or anything... I'd like to hear about the other side. I'm surprised that a huge scrum failure is possible because the customer is generally shown everything at regular small intervals, so it's hard to imagine how a project could get so far off course.)
