Arlo does a little bit of everything, but what he really does is inspire courage. He has gone back and forth several times between management and in-the-trenches development on technically sophisticated products. He challenges every assumption he can find, and helps people learn to change always and continuously. He has been involved in Agile since 1999. Yet in the middle of that period he worked for 2 years in a rigorous, effective, and pro-people Waterfall development shop. He’s a strong believer in discipline and the agility that comes from it, in punctuated continuity, and in change as the only constant. Don’t do anything he says, but learn why he says it and come up with something better. The best compliment he’s recently received was when a co-worker termed him the Company Jester because Arlo always has permission to laugh at the King.
