 Right, good afternoon. I'd like to talk a little about individuals and interactions over processes and tools. This is a tagline that gets thrown around. It's kind of listed as the first value, first comparative value in the agile manifesto. And this big question is to what does it really mean? Because in many cases I find that when people are pursuing agile, either specifically because they have something in mind or even broadly just we're doing agile because we feel we ought to because other people are, so not necessarily a good reason. There is a surprising reliance on the second category. For some people, agile development seems to be associated with a very strict interpretation of process. For other people, there's a little thought bubble that goes on. They think of the tools, they think of their testing frameworks, they think of their continuous integration frameworks, they tend to associate it with these various mechanical features. Now these are useful, these are good, I'm not going to say they're bad, that's definitely not the idea of the comparative. But there is this question about understanding a little bit more about the individuals and indeed how they interact. So I want to explore that a little bit. I guess a brief bio, my brief bio is I'm Kevin Henney and I walk around the stage a lot so I'm moving this out of the way because otherwise there will be damage to me and this. Right. And my back, that's just done the right thing. Okay. So I've been involved in software type stuff. Probably the most relevant things here are fact, a long term interest in patterns and the relationship that patterns have not simply to design but the way that people reason, discuss and view and frame problems and their solutions. And curiously enough, this crowd source, open source book, 97 things every programmer should know, which as the editor, I managed using everything I'd learned from agile development. How do you get a bunch of disparate volunteers who've never met one another to contribute and write well? This is an interesting problem. And it turns out that a number of the techniques that I learned were very relevant to this. However, let's go back to this, which I hopefully has everybody has good site recognition of, understands that the
