Same here, but I also wonder how much of a structured approach was even possible. I suspect it was destined to be an exploratory, iterative experiment no matter how hard the team tried to wrap structure around it.

Having worked in R&D, production, change management, etc, I've seen all kinds. Some projects lend themselves very well to an orderly approach. Some resist mightily. Trick is to identify early on what is most appropriate and do your damndest to make it happen and not fight what's right.

And if it doesn't succeed, make sure the lessons learned aren't lost. Today's failures might be seeds for some wonderful innovation tomorrow. Thomas Edison would tell you.
