XP - Extreme Portraiture

One of my favourite talks explaining why XP does what it does in software development is J.B. Rainsberger's 7 minutes, 26 seconds, and the Fundamental Theorem of Agile Software Development

Joe saw a sketchnote I had done on this talk and asked if I could help him out...

He was considering revamping his blog (and maybe other of his sites later) and asked if he could use one of my illustrations - a portrait of him - on the site. Joe has indirectly helped me a lot over the years through blog posts and videos of his talks so, of course, I said yes. The result is below or you can see the real thing here
