Over a month later, I am finally getting around to blogging about this great conference I not only attended, but spoke at. Apart from open spaces, and leading semi-prepared informal discussions at user groups and stampedes, it was my first time presenting at a conference.
David Anderson‘s keynote was of course very interesting. I found his idea of a second, or multiple, committal points interesting, and the idea that the lead time should stop at the first non-WIP-limited queue or buffer (and presumably start again from the next WIP-limited queue or buffer). I am not convinced on that last point. I think even if a buffer should be non-WIP-limited because it is under the control of an external stakeholder, it could still make sense to include time spent there in the lead time, if you are using it to predict how long things might take. Why not just take both lead times I guess.
He also mentioned that the cost of delay was perhaps more useful at the portfolio level than the user story level, expressed some interesting opinions about calculating business value, and combining that with strange cost estimates, which is how a lot of product owners etc currently spend a lot of time. An alternative could be to focus on risk. Capacity-constrained people should never work on optional things like estimation as it brings the whole team capacity down, only those with slack capacity should do such things. The bulk of his talk was about liquidity which is something I need to spend a lot more time looking into. He presented some interesting metrics such as “pull transactions” per person, or per unit of money.
Laurens Bonnema gave an interesting talk that appealed to me, because talked a lot about the more subversive aspects of culture hacking. There were a lot of good tips for being an effective change agent, and not the usual types of tips one reads either.
The evening meal was pretty classy. Lots of little courses, very delicious. It was a great location too by the way: De Fabrique
The next morning I realised I drank too much at dinner the night before and was worried I wouldn’t survive my talk. I found Don Reinertsen‘s keynote a little heavy going. Lots of graphs and maths and I had trouble relating it back to the concrete experience of helping a team develop software. Someone else mentioned he should try story-telling. Then I gave my talk. I think it went well, but there was a minor technical hitch. The screen-saver kept kicking in,and the main presentation display kept working but my secondary display with the timer went dark. So I lost track of time and had to really rush through the last bit. I still went a few minutes over time. My hangover wasn’t an issue. Once I was standing up and moving around and talking it kind of went away.
You can see the slides here:
After that Jasper Sonnevelt and Sarah Reeder made us dance. I saw Arne Roock‘s nice looking presentation about creating a Kaizen culture. The last session I attended was probably my favorite. My “classmate” from my MSc program, Steve Tendon, presented a very informative presentation about the Theory of Constraints, with really great looking slides. Steve should really present at conferences more often!
On the last evening a few of us joined up with the local Theory of Constraints community and went out to dinner. We went to the Oudaen where we had the surprise menu, but it was also a very classy dinner with lots of little courses.
Over all I really enjoyed this conference. I am starting to get to know a few people now, and actually look forward to catching up with them as much as the actual content. 2012 was a fairly quiet year for conferences, but I will definitely have to look at not only attending but talking at more conferences in 2013. I already have one unconference on my plan. Play4Agile in February.
