One of my biggest treats of No Fluff, Just Stuff symposia is the conversations you get into before and after. On the way to the airport in Orlando, Glenn Vanderberg, David Bock, and I shared a crowded airport shuttle (with a bunch of vacationers who didn't share our conversation). Glenn talked about some fascinating writing he's doing with feedback loops in Extreme Programming and David talked about the Agility Index Measurement. My contribution? A interested but dazed stare.
David has since blogged about AIM (nice acronym, very managerial) here. He's soliciting for people to help him develop a more or less objective measurement of just how agile a team really is. To quote: "the point is I WANT A WAY to compare the capabilities of teams implementing these [agile] processes." If this topic interests you, wander over to his blog and put your own $0.02 for what categories should be measured.
