 I'm an agile coach with Raleigh. Every two or three times a year all the coaches get together where we share our learning, our knowledge and brainstorm ideas and share problems. Last summer at one of these gatherings one of the coaches was talking about the fact that she was going to have to do and do an introductory to Waterfall, an introduction to Waterfall. She wasn't quite sure how she was going to teach this as an agile coach. And it was lunchtime, we weren't taking it that seriously. And I kind of came up with this great presentation and I suggested all she has to do is stand up in front of the audience and say, no, no. And then we put together a little slide deck which had the word no in lots of different colours and fonts. And then one of my colleagues found this video and said, just play them the video. And that's relevant to this talk because actually the way I think about Kanban is you don't have to say no. The way I'm going to talk about this afternoon is some ways to think about your process so that the choices that you make are just that, their choices. And they're not right choices and they're not wrong choices. And there's no best practice and no dial that you turn up to 11 because that's clearly the right thing to do. They're levers. So this is where the idea and then the title of the talk, leverage points come from. Sometimes you might want to pull the lever back a bit, sometimes you want to push the lever forward a bit. And the combination of levers is what makes the whole thing work. I'm Carl Scotland. As I said, I'm on a coach with Raleigh. This was me a long time ago in a former life. It was about when I was at the BBC. This is a mind about when I started. Getting to grips with Argyll. It was a kind of good playground for me. Got to experiment with different ways of doing things and XP and Scrum and DSDM. And one of the projects, one of the, well it wasn't really a project. It was a product and an ongoing stream of work before I kind of knew that was a good way of doing things. We won a BAFTA. So I'm kind of very proud of that. That's me on that side just in case you couldn't watch that. That was my project manager on this side. So Kanban. Who knows what Kanban means? Soundboard. Literally, correct. Kenji's not in the room, is he? So this was actually written on the back of our Kenji Hiradne's business card. He gave it to me back in 2007 and I've kept it to this day. Partly because it reminded me how to write it.
