Quite the opposite. Agile is about testing ALL THE TIME and building incrementally. They have flown humans right after a single successful cargo mission. Did they have no further anomalies in the second mission? I seriously doubt it. Now they have a bunch of issues on the RCS and reentry rockets that can't possibly be entirely new (unless someone changed something and people have flown an untested critical component). Worse for Boeing, those components are procured from a third party which now they must be questioning how much QA went into them.
Was not an optimistic introduction to the industry...
But there were still some good people, and good teams. But yea there were times where the importance of agile methodology in being preached by an executive agile coach before an emergency task force meeting while planes are falling out the sky.
