How I happened to sit on the Industry Sofa
Nearly at the end of the XP2011 Conference in Madrid, I stood in the garden together with a few colleagues from different countries and different companies to say goodbye. We talke a bit about the new ALE network we were all in some way participating in it, and at some moment, Olaf Lewitz said something like: "let me summarize the results of this session shortly..." and someone else said, "oh, we are actually in a session?" - and it turned out that this had started as a follow up on the session about planning the brand new ALE 2011 conference, which would take place this time in Berlin but it was supposed to tour through the European (= European Song Contest member) countries.
He listed the current state of "sofas" that were planned, instead of the usual "chairs", putting the emphasis on the collaborative way it was going to be planned. - I said I was missing an Industry Sofa, for getting enough really interesting industry speakers into this new conference. Oh yes, - why don't you actually take it yourself, you have a lot of industry contacts?
So this is how I happened to occupy the Industry Sofa, and before I finally left the venue, I convinced Ken Power from Cisco/Ireland to share this sofa with me, and I still thought a third member covering perhaps Eastern Europe or Scandinavia would be great.
When I arrived back home, I already found Olaf's blog entry " I am organizing a conference" and saw our "Industry Partner Sofa" listed with all the others - oha! Some work to be done!
Very quickly, also the basecamp accounts were set up by Sergey Dmitriev in Norway, and a group of people started to fill the conference website http://ale2011.eu/ with all the infos we have already agreed on.
Decisions with 47 distributed organizers
I have to admit that it is sometimes very difficult to find out whether something that has to be done is actually done by someone already, or if a decision has been taken finally, or who are all the people that have to be asked to get to a final decision about something. Every day I am going through quite a couple of mails in different threads, mainly on my mobile, when I am sitting in the train coming back from work.
But as all the organizers are agile and lean people, it is quite less stress than I had thought a few days after start. We managed to post the Industry call for papers as quickly as needed. I sent the call to many people I know personally, and so did the other sofa members, Will Gill (Australian at Nokia in Berlin) who joint us the next day, and Pierre E. Neis in Luxemburg.
We found way to distribute information quickly and also have people quickly decide something. For example, the deadline shift this week was decided through a Doodle sent around to everybody, ending 24 h later. To get and share info directly, there are Organizers Skype calls every few days.
It is very interesting and challenging. Of course, a week before the deadline for submitting talks, there were only about 3 contributions. But on the second last day, we had 36, and on the last day, after we had decided to extend by one week, there were already about 50. WOW!
Now we are all reviewing and commenting. - Still, there is nearly a week left for submission of new talks.

XP 2011 Open Space session: Teaching TDD to a Team so that it sticks
On XP 2011 conference in Madrid, I invited to an Open Space session named "Teaching TDD to a Team so that it sticks". I stated the problem below, and a couple of interesting people showed up and gave very helpful hints, among them Charlie Poole, the inventor of NUnit, as well as Patrick Kua and Alexandru Bolboaca. I have integrated some hints from an earlier discussion of the topic with Emily Bache and Johannes Brodwall at the ACCN in Oslo.
The problem description:
Let’s take a couple of Scrum teams who have already been doing Scrum for a while, but are still lacking some technical practices. Agile coaches are convinced that Test Driven development (TDD) would help them create better and more solid code.
Some have had the opportunity to attend a TDD or XP in general training session, but only very few have taken back something to their work.
What could be the reasons for that?
· TDD is not intuitive, but you have to practice a time to overcome the first problems
· If they are the only ones in their teams, it is difficult to stick to it, not having whom to ask
· There is also pressure to take on constantly work from the product backlog, and work will be first slower than without TDD – they need the consent of their Product Owner
· Maybe it has not been communicated enough that management and Product Owners would tolerate some initial productivity loss, and at which time
· The examples from training were easy, but the own project is really hardcore programming J
· In some project setups, it may not be the same developers who profit from good code, as bugs are corrected by someone else => no closed feedback loop
· All participants should be voluntarily doing the training
· The training should be done focusing on one team at a time
· The training can be 2 or 3 days off site – not in the normal work environment
· To explain TDD well, code examples that are not from the own project are used at least the first 2 days
· it is helpful if code examples are from the main programming language that the participants are using
· The proper UT frameworks need to be installed on the developers' machines when they are starting
· A code retreat could be used for the first phase – this is a couple of developers sitting together and working on the same problems several times, deleting the code in between – outcome is that it is reasonable to create good maintainable code
· A coding dojo is also a good technique – a group of developers solving a problem, doing TDD, but only one pair at a time will actually work on the code, while the others can look on the projector, and one dojo participant will change from time to time
· After the participants have some good idea about TDD and first practice, it will be good for credibility and transfer to their own work to look at some own code examples from the team’s real life project
· The trainer needs to prepare for that, so he/she can work with that code
· The workshop needs to bring the mindset change to “it is fun working with TDD”
· After the initial training, there must be an agreement with the Product Owners how much time can teams spend per week/per iteration on practicing TDD
· Follow-ups take place in the normal work environment: coach pairs with people in a team on real programming problems
· From time to time a code retreat or coding dojo to learn more interesting things (refactoring, cleaner code) and practice TDD in volunteer group will lead to strengthen the practice and amplify the learning

XP 2011 conference in Madrid: report of a newbie
Well, I have to admit that while I have been attending and even presenting on a couple of software conferences in the last few years, it was the first time I visited an XP conference. It was kind of that the idea struck me early in April 2011: there is an XP 2011 conference going on inMadrid, soon, they will talk about globalizing agile – this is just what I am doing in my daily work and what I am interested in, and on the other hand, XP means technical agile practices, and this is what our teams still need to develop more.
The intutive decision turned out to be quite good. I met many interesting people – some of the already known from ocasions like the AgileEastern Europe conference in Kiev, the Scrum Gatherings in Stockholm or Munich, or small events like the Agile Coach Camp Norway, or even from Siemens-internal agile conferences some years ago. And I met quite new persons, at least for me, who enriched my view of the agile world.
The XP conference seems to build a unique link between industry practicioners and university investigators. It is great to see how the Master or PhD students profit from the direct discussions with people who have global agile experience in the industry. On the other hand, it gives the industry people quick access to new research results.
There are several topics where I found particularly interesting information:
- Agile and Leadership – here to mention the keynote from Esther Derby and the presentation from Jurgen Appelo
- Industry reports – Even the ESA converted from waterfall to agile, as reported by Rui Santos and Marc-Elian Begin. In companies, I have now seen several times seen the agile release train by Dean Leffingwell applied – also in the report by Gabor Gunyho from F-Secure.
- Agile coaching – a very practical workshop with Patrick Kua I had the pleasure to particpate in.
- The initiative for creating a vision and rules for the recently born Agile and Lean Europe network (ALE) – and a lot of activites following up, including a new conference rotating through European countries, starting September 7.-9., 2011 in Berlin.
- And last not least the results of my open space inquiry about Teaching TDD to a Team so that it sticks.
I will follow up to these topics with separate blog entries in the next couple of days, starting with the TDD open space.
