I’m excited to be going to Fortaleza at the end of this month to present and organize Agile Brazil 2011. Last year in Porto Alegre I decided to focus on the organization aspects of the conference, but this year I decided to present again. Even though I’ve been participating in conferences around the world, my last talk in Brazil was in 2008 and I really miss being around the Brazilian community and sharing experiences with everyone. That’s why I’m happy to be presenting in (mostly) Portuguese again :-)

Managing your technical debt – June 29th

In this 50 minutes talk, I will cover a few practices and ideas I’ve used and seen used in projects to manage technical debt responsibly. Some of the topics I will cover are:

• What is technical debt and what are the consequences of incurring it
• Ideas on how to identify “hot spots”
• How to prioritize and plan the payment of your debt
• Tracking and visibility
• How to avoid incurring debt
• Communicating the importance of paying technical debt to non-technical managers and stakeholders

Slicing and dicing your user stories – July 1st

Co-presenting with Jenny, in this 50 minutes talk we will discuss the benefits of working with small user stories, and present different ways to split requirements into user stories. The session will cover topics related to:

• What makes good user stories
• How to break down features into smaller chunks without losing track of the overall goal
• Different ways to split stories into vertical slices
• Helping stakeholders to track and understand how the feature will be delivered piece by piece
• Planning the delivery to increase feedback

Refactoring Katas – July 1st

In this 10 minutes Lightning Talk, I’ll share an idea I’ve been using to practice refactoring. Using a different Kata format, I will explain the mechanics and quickly demonstrate it in practice.

If you haven’t registered yet, you can still register online. And if you are around Rio and São Paulo the following week, I will be giving ThoughtWorks’ AWS Training, which you can register here. I’m looking forward to seeing you in Fortaleza!

Agile Brazil 2011 – Eu vou!

Estou empolgado com a viagem para Fortaleza no final do mês para participar e organizar a Agile Brazil 2011. No ano passado em Porto Alegre, eu decidi me focar mais na organização do evento, mas esse ano resolvi apresentar. Mesmo estando participando de diversas conferências ao redor do mundo, minha última palestra no Brasil foi em 2008 e eu sinto saudade de estar compartilhando experiências com a comunidade brasileira. É por isso que estou feliz por apresentar (na maior parte) em Português novamente :-)

Gerenciando sua dívida técnica – 29 de Junho

Nessa palestra de 50 minutos, eu vou apresentar algumas idéias e práticas que tenho usado para gerenciar dívida técnica de forma responsável. Alguns dos tópicos que irei abordar:

• O que é dívida técnica? Quais os sintomas mais comuns e qual as consequências do acúmulo de dívida técnica?
• Formas de identificar e encontrar “hot spots”
• Como priorizar e planejar o pagamento da dívida
• Tracking e visibilidade
• Como evitar o acúmulo
• Idéias para convencer gerentes e pessoas sem conhecimento técnico sobre a importância de pagar a dívida

Slicing and dicing your user stories – 1 de Julho

Apresentado junto com a Jenny, essa palestra de 50 minutos vai discutir os benefícios de usar user stories pequenas e apresentar diferentes formas de dividir requisitos em histórias. A palestra vai cobrir tópicos sobre:

• Características de boas user stories
• Como quebrar funcionalidades em pedaços pequenos sem perder a visão do todo
• Diferentes idéias para quebrar requisitos em fatias verticais
• Formas de ajudar stakeholders a rastrear e entender como uma funcionalidade será entregue em pedaços menores
• Planejamento da entrega para maximizar o feedback

Refactoring Katas – 1 de Julho

Nessa Lightning Talk de 10 minutos, vou compartilhar uma ideia que tenho usado para praticar refatoração. Usando um formato de Kata diferente, vou explicar a mecânica do exercício e demonstrar um pouco como ela funciona na prática.

Se você ainda não se inscreveu, ainda pode se inscrever online. E caso esteja por perto no Rio e em São Paulo na semana seguinte, estarei ministrando o Treinamento AWS da ThoughtWorks, que você pode se inscrever aqui. Vejo vocês em Fortaleza!

The second day of the conference was one of the busiest for me, and it started with a great keynote…

Keynote: Leveraging Diversity in Parallel: Perspective, Heuristics and Oracles – Scott Page

Scott Page, author of “Complex Adaptive Systems: an introduction to computational models of social life” and “The Difference: how the power of diversity creates better groups, firms, schools, and societies”, gave the introductory keynote on the topic of diversity. His talk was one of the most interesting of the conference to me, since he showed the “algebra of collaboration” or, in other words, what are the factors that make diversity work in a team. A few of the highlights for me were:

• The importance of bringing different perspectives to the table: his example of playing the card game “Sum to 15″ as Tic-Tac-Toe was really good.
• When it comes to problem solving, hardness is not the same as complexity: in hard problems, the solution space have lots of peaks (hard to find the global optimum); in complex problems, the solution space moves (even if an optimum is found now, the entire landscape might change due to external conditions).
• I’ve read about the Wisdom of Crowds before and saw James Surowiecki’s keynote at Agile 2008, but Scott showed the formula behind it: crowd error = average error – diversity. In other words, the amount of diversity will decrease the average error of a crowd.
• Netflix Prize: an amazing story about a three-year-long contest put up by Netflix to beat on their own algorithm that predicts how much someone is going to enjoy a movie based on their preferences. What started as a competition to come up with the best algorithm, ended up in a race to collaboration, when the teams running for the prize started combining their approaches and finding that the diversity on the combined algorithm would yield a better result than any of the solutions in isolation. You can read more about this story here.

“Diversity becomes more valuable as the problem becomes harder and harder” — Scott Page

Thawing the “Design Winter” – Michael Feathers

The second talk I attended in the morning was about how there’s not much going on in the software design space lately. Michael Faethers started off noting that our industry is very generational: a lot of the innovation on development techniques in the past, were followed by a wave of design books around the topic (Structured programming, then Structured Analysis and Design; Object-Orientation, then OO Analysis and Design; and so on). Michael said he decided to stop when he saw the book “Aspect Oriented Programming with Use Cases” :-) But with Agile techniques, the last good reference about design was Martin Fowler’s “Is Design Dead?”, from the early 2000’s. Some of Michael’s points on the topic were:

• Design happens around constraints: everytime there are decisions to be made around how to develop a given piece of software, there will be design happening.
• Architecture is design: people should acknowledge that and recognise software architecture as design.
• Look at design as the composition of “things”, not just classes.
• Design are the trade-offs and the discussions you make when taking a particular decision.

I found it an interesting take on the topic, and agree with most of his claims about software design. I personally think that, as a TDD practitioner, I spend a lot of the time doing design (coding is a design activity, not just typing). I also agree that we need to think about design in a higher level, when defining the system/application architecture: those are the decisions that will be hard to change. To me it’s about being able to combine those early-and-hard-to-make decisions with the emergent aspects that you will discover with time, as your system evolve. What you can’t expect is to get it right on the first time, but be flexible enough to incorporate your learnings into something that can evolve.

The Five Habits of Successful Lean Development – Mary Poppendieck

This was the only session I ended up attending on the topic of Lean/Kanban on this conference. Mary summarised 5 habits of successful lean teams:

• Purpose – “Why are you doing it?” In lean companies, workers have a high sense of purpose and understand how their jobs relate to the common goal/vision of the company.
• Passion – “We Care” Having individuals with intrinsic motivation will produce high quality results.
• Professionalism – “Build the right thing” customers don’t want software. If they could get the same thing without software, they would go there. But also “Build the thing right” as simple as possible – and no simpler
• Pride – Expect local decisions, and push them to the front-line workers. They are effectively engaged in delivering superior customer outcomes.
• Profit – “GM stays in business to make money. Toyota makes money to stay in business.”

As catchy as it sounds to summarise Lean into these “5 Ps” mnemonics, I found it to be just a partial view into the topic. Other strong aspects of Lean are the focus on people, and on leaders taking an active role as teachers. These were some of the things I would also expect to see in a lean organisation that I found missing on this “5 Ps” view.

Done Considered Harmful – Marcus Ahnve

This was a lightning talk by my friend Marcus, and I found it really interesting. It was provocative, by picking on a widely discussed concept in Scrum: the Definition of Done (and things like Done-Done, or Ready-Ready). Marcus’ point is that by calling it “Done”, it creates a fake state that usually translates to a hand-off to a different team, or a partial completion state that encourages local optimization. From Lean thinking we know that hand-offs are usually a big source of waste (along with the queues that are usually associated with it).

I was worried he would only present the problem in the talk, but was otherwise pleased with the approach he suggests to tackle this problem: instead of “Done”, call the state by what it represents (e.g. “Ready for deployment”, “In UAT”, “In Production”). Look at the last column in your wall from a hand-off perspective and treat it as inventory in the end-to-end value stream: you might be accumulating WIP and optimizing locally instead of improving the overall effectiveness of your value stream.

Test Automation at Enterprise Scale – Mark Streibeck

This was the technical session I most enjoyed in the conference. Mark talked about the story behind creating Google’s infrastructure to run tests in a massive scale, across teams and codebases, and to provide useful feedback and reports to their developers and teams. Some of the highlights for me were:

• Scale of the system: they run 60M tests/day, including browser tests (cross-browser and running multiple configurations). More than 1700 projects use it (they account that ~80% of all tests are run on this system). The system runs in ~5000 cores.
• Sharing their challenges: this project involved a lot of infrastructure work, which took a lot of time at the beginning of the project, to come up with a scalable architecture. Also, they had to design a UI for a system that solves a known problem in a different way. They also had a lot of work when integrating with various heterogeneous build/test systems that were already in place accross different teams.
• Rollout process: the way they planned and executed the rollout across the company: starting with a few “early innovators”, organic rolling our to a few “early adopters”, and using feedback from these early teams to “fix it” when helping the “early majority” (they even had setup a day where the entire software engineering group could fix things to make the system better.)
• Creativity when solving problems: one of the biggest problems on building and running tests was fixing dependencies issues for projects. Instead of tackling the difficult task to try and solve those issues as a system feature, they focused on improving the way that these issues are displayed on the UI. Just showing the dependencies and letting the teams see it and fix it by themselves proved to be a much simpler solution to the problem.

Conference Banquet and Keynote

The second day finished with a keynote and banquet at the Student Society building. The keynote was presented by Bjørn Alterhaug and John PÃ¥l Inderberg, and the topic was “Improvisation: Between Panic and Boredom. Perspectives on teamwork, dialogue and presence in music and other contexts”. It was a very interesting talk about improvisation in music but, most of all, it showed me how practice can lead to mastery: the dynamics between the two musicians and how they communicate to each other through music was a fine example of highly skilled individuals that can achieve incredible results in a highly collaborative environment. A great talk to an Agile audience :-)

The evening finished with an amazing banquet and more music concerts, including a “Keep of Kalessin” show – an Epic Metal norwegian band.

Tuesday was the first day of the XP2010 Conference, being held in beautiful Trondheim, Norway. I was on a morning flight from Oslo and only managed to arrive at the venue in the afternoon. It was nice to see a lot of my friends again – so far, I managed to count 8 Brazilians, which is probably the highest number in XP conferences so far :-)

Functional Programming with XP – Amanda Laucher

The first talk I attended in the afternoon was from my friend Amanda Laucher. She presented on an interesting topic, discussing how Functional Programming languages and concepts can relate to today’s Agile practices and principles. Some of the lessons that I took away from her session were:

• Functional Programming and Testing: she talked about different aspects of Functional Programming and how you can approach testing them. Things like: testing for lazyness, testing monads, minimizing side-effects, testing on strong vs. weak typed languages, testing on static vs. dynamic typed languages (and useful tools like quickcheck). Even though I don’t have a lot of professional experience in FP languages, one particular topic resonated quite strong with my experience: “you need to know FP before you TDD in FP”. On our Coding Dojo in São Paulo, we learned a similar lesson when trying to TDD algorithms: you need to have an idea of how to solve the problem before you drive your solution with TDD. If you don’t know how to solve your problem, TDD won’t give you the solution.
• How to learn a new language: I really liked Amanda’s pragmatic approach to learning new languages. I particularly liked her reference to the Functional Koans, specifically designed to teach you features of a new language by giving you failing tests that you need to understand and fix. This approach separates the learning of the language, from the learning of the testing tool, or TDD. This is a problem I found when trying to learn a new language by first looking for the testing frameworks available, before understanding the languages’ constructs and concepts.

System Metaphor revisited: The lost XP practice – Joshua Kerievsky

My second session of the day was Joshua Kerievsky’s take on the System Metaphor, an XP practice that he asked on his review of Kent Beck’s second edition of the XP book to be removed, and that has been later applied with great success on Industrial Logic’s main product.

He first talked about metaphors in general: how they link a source domain to a target domain, how they’re always partial, and how people need to have experienced the metaphor in the source in order to apply it to the target. He also briefly compared the role of a System Metaphor with the Ubiquitous Language, as described by Eric Evans on Domain-Driven Design (this is something I came across a while ago too). Finally, Joshua described the benefits of a System Metaphor, summarising them on the three I’s:

• Illumination: when the chosen metaphor is good, it will provide illumination into aspects of the system design, clarifying unfamiliar design via a familiar domain. It will help describe not only static structure, but also the runtime behaviour of the system. I particularly liked how he described two ways of understanding the Composite pattern using concepts from the music metaphor.
• Inspiration: a good metaphor will also provide inspiration for new ideas. It provides a system of names from which these ideas may flourish. You might consider ideas from the source domain and evaluate how to apply them to the target. The only thing you need to be careful is that the metaphor is partial, so stretching it to fit your situation might not always be a good idea.
• Integrity: when the source has a rich, familiar set of related parts, it will provide more integrity when applying it to your target. It will also have more integrity when the mapping between the source and the target is strong. If integrity is high, mixing other metaphors won’t weaken the overall structure.

What I found interesting on Industrial Logic’s use of the System Metaphor is that it is visible to the users of the system. If you’re taking one of their eLearning courses, you can see and interact with concepts from the music metaphor such as albums and playlists. The previous examples I’ve heard about uses of the System Metaphor were internal to the team and the business stakeholders, to improve communication. You can read more about how they discovered and applied the music metaphor here.

Conference reception – Nidaros Cathedral

The first day ended with an organ concert at the beautiful Nidaros Cathedral, followed by the conference reception with drinks and food at the Archbishops Residence and Palace Museum.

I’m one of the organizers of the program committee for Agile Brazil 2010, and we’re very happy to announce that ThoughtWorks has agreed to sponsor the visit of Martin Fowler, our Chief Scientist, as one of our keynote speakers. Since this is Martin’s first visit to Brazil, I decided to ask him some questions that I thought would be of interest to the participants, and he has kindly agreed to participate in this mini-interview:

Q: What have been keeping you busy lately?

Martin Fowler: Overwhelmingly it’s my upcoming book on DSLs. I found writing books to be hard work, and it’s actually getting harder. By June I expect all of the content will be cast so my mind will be able to get away from it – which I’m very much looking forward to.

Q: What are your expectations about Agile Brazil 2010?

MF: I try not to have expectations about things, that way my mind can be open to the reality when I see it. I’ve been doing conferences frequently for two decades now, so it’s hard to get excited about them. I am excited about coming to Brazil. It will be my first time in South America and both I and my wife have long wanted to come down.

Q: What are you going to talk about in your keynote?

MF: I have no idea. I often don’t decide on my keynote until very close to speaking – often doing extemporaneous talks <http://martinfowler.com/bliki/ExtemporarySpeaking.html>. Recently I’ve been doing keynote talks consisting of three or so talklets, some with slides, some without. But exactly how I’ll do it is something I may only decide the night before.

Q: How do you see the Brazilian software community influencing the future of Agile?

MF: It’s hard to say, as I’m not that familiar with the Brazilian software world. I’ve been very impressed by the Brazilian ThoughtWorkers I’ve met over the years, so I know there’s great potential here. I’m generally keen to see more varied cultures contribute to the software world, I think it’s an important part of us growing as a profession.

Agile Brazil 2010 is going to be an incredible conference, and we’re inviting speakers to submit session proposals (the deadline is approaching: 28/Feb!). Don’t miss the chance to see and talk to Martin Fowler, as he’s one of the few speakers I know of that can put together a first-class keynote on the night before :-)

Don’t forget to follow @agilebrazil on Twitter for conference news, and hope to see you there!

[Agile Brazil 2010] Martin Fowler pela primeira vez no Brasil!

Como um dos organizadores do comitê de programa da Agile Brazil 2010, estamos felizes em anunciar que a ThoughtWorks aceitou patrocinar a visita de Martin Fowler, nosso Cientista-Chefe, como um dos keynotes do evento. Como esta será a primeira vez que Martin visita o Brasil, decidi fazer algumas perguntas que julguei interessantes para os participantes do evento, e ele concordou gentilmente em participar desta mini-entrevista:

P: O que tem te mantido ocupado ultimamente?

Martin Fowler: Surpreendentemente é o meu novo livro sobre DSLs. Eu acho que escrever livros é um trabalho árduo e na verdade isso tem se tornado cada vez mais difícil. Até Junho eu espero que todo o conteúdo esteja definido assim isso vai poder sair um pouco da minha cabeça – algo que estou realmente ansioso para acontecer.

P: Quais são suas expectativas para a Agile Brazil 2010?

MF: Eu tento não criar expectativas sobre essas coisas, assim minha mente pode estar aberta para a realidade quando eu a ver. Eu tenho participado de conferências frequentemente há duas décadas, então acho difícil me empolgar com elas. Mas estou empolgado em visitar o Brasil. Esta será minha primeira vez na América do Sul e tanto eu quanto minha esposa estamos ansiosos há tempos por essa visita.

P: O que você irá abordar no seu keynote?

MF: Eu não tenho idéia. Eu geralmente não decido o assunto do meu keynote até uma data muito próxima do evento – geralmente fazendo palestras extemporâneas (improvisadas) <http://martinfowler.com/bliki/ExtemporarySpeaking.html>. Recentemente eu tenho feito keynotes com em torno de três pequenas palestras, algumas com slides, outras não. Porém decidir exatamente como irei fazê-lo vai ser algo que eu possivelmente decida na noite anterior.

P: Como você vê a comunidade brasileira de software influenciando o futuro dos Métodos Ágeis?

MF: É difícil dizer, pois não estou tão familiarizado com o mundo de software brasileiro. Eu tenho me impressionado bastante com os ThoughtWorkers brasileiros que conheci ao longo dos anos, então eu sei que existe um grande potencial aqui. Em geral eu gosto de ver uma variedade maior de culturas contribuindo para o mundo do software, pois acredito que seja uma parte importante para crescermos como profissão.

A Agile Brazil 2010 vai ser uma conferência incrível, e estamos convidando palestrantes para submeterem propostas de sessão (a data limite está se aproximando: 28/Fev!). Não perca a oportunidade de ver e conhecer o Martin Fowler pessoalmente, pois ele é um dos poucos palestrantes que conheço que consegue preparar um keynote da mais alta qualidade na noite anterior :-)

Não esqueça de seguir @agilebrazil no Twitter para notícias da conferência, e espero ver vocês por lá!

I’m helping to organise the first nation-wide Agile conference in Brazil, that will take place in Porto Alegre next 22-25th June. Agile Brazil 2010 is a joint effort to bring together all the Agile communities around Brazil (industry and academy), and the conference goal is to promote communication and collaboration among its attendees aiming to disseminate the Agile culture in the whole country. Some of the confirmed international guest speakers are ThoughtWorks’ Chief Scientist Martin Fowler, Philippe Kruchten, and David Hussman.

After working the past month on building the submission system, I’m happy to announce that we’re inviting you to join as a speaker of this great event too! Tell Brazil about your experiences, present your research and share your products and learnings! You can find the deadlines and the submission guidelines at:

http://submissoes.agilebrazil.com

To find out more about the conference, please visit our website, or follow @agilebrazil on Twitter.

Agile has shown that doing prolonged analysis upfront bears little to no value to the customer. However, doing none means the project lacks the direction that it needs. The question is, how much analysis is enough before the project starts? This will be the theme of my recently accepted “Inception Workshop: Kickstarting an Agile project” that will be pair-presented with Jenny at XP2010, in Trondheim, Norway.

My journey to find the right balance between a generalist/specialist in software has led me to projects where I had to play not only the developer role, but several to varying degrees (PM, BA, QA, Architect, Coach, team lead, …) This is my attempt to share my knowledge towards those different areas, by pairing with an experienced BA and talking about Agile project initiation.

In this workshop, we will share our experience of participating in several project inceptions. Participants will work in a condensed project inception, solving a business problem and using some tools to shape the project for delivery. Our goal is also to learn from other practitioners about the tools and techniques they’re using successfully in their projects.

More details about the session can be found at the XP2010 session description:

http://xp2010.agilealliance.org/node/5380

We are very excited about this session, and we hope to see you in Norway to participate and share your experiences too!

I’m here having a great time in Chicago, at Agile 2009. I will write more about the sessions in later posts, but I wanted to talk about the Coding Dojo we ran at the Open Jam. Organised by my friends from the Dojo@SP (thanks Hugo, Mari, and Thiago!), we tried a projector-less format that went really well. I wrote about the Kake Format a while ago, although the name changed.

It was a lot of fun, and we were lucky to bump into Emmanuel Gaillot around in Chicago, who made it to the session as well. We solved the Kata Bowling in three different stations: one in Ruby, one in Haskell, and one in Java. The code is available on GitHub, and these are some pictures I took during the session:

If you want to try out a dynamic format, where people have more chance to participate and train different skills, and you don’t have a projector available, I urge you to try out the Kake Format on your Dojo and share your experiences!

Last week marked the 10th edition of the XP 200x conference, held in Sardinia, Italy. Me and Francisco were there to present an extended version of our Lego Lean Game. Being selected as the first session on the first day of the program, we were expecting a small audience, but it turned out to be quite well attended by about 20-25 people.

We started the session a bit delayed, due to the lack of room organisation: I was a bit shocked when we arrived and the room was arranged as a normal “lecture room”, rather than the usual group tables (that we requested a week before). Projector and flipchart were not available, so it took us about 15 minutes to have everything ready to begin.

The slow start, however, did not got in the way of the overall workshop. We have designed the activities in a flexible way that allow us to adapt their length just-in-time so we still managed to cover everything we wanted without having to rush.

The first half of the workshop was mostly the same version we presented last year in Buenos Aires, with slight modifications based on feedback we got from participants. The second half, however, was mostly new and we included an activity to allow each team to come up with their own processes (rather than following ours). This turned out to be a great success! Each group came up with different ideas and, by watching the other teams perform, we had an interesting discussion about the different approaches and results. We now think that the original version is too condensed :-)

The feedback we received after the session was great and a lot of people asked us for the material to run the session themselves. Me and Francisco have a “game package” that we can share for those interested in running the game. Get in touch with us if you’re interested! You can find more photos of our presentation here, here, and here (thanks to Hubert for sharing his pictures!). The slides are also available:

We are very interested in your feedback. So, if you were at the conference or want to use the material to run the workshop, please let us know! Share your experiences and help us make it better!

XP 2009 is happening between 25-29th of May in Sardinia, Italy and I will be there attending and presenting some interesting workshops:

• The Lean Lego Game: Me and Francisco have been improving our workshop since we last presented it at Agiles 2008 in Argentina, and we will be presenting a long version (180 minutes) on Monday, May 25th. We have just a few “seats” available to participate on the session (20-24) and it will be occupied in a first-come-first-serve basis. If more people show up we have plans to try and not reject anyone, though.

• Test Driven Development: Performing Art: Emily Bache kindly invited me to present a Prepared Kata at her workshop and I will be pairing with Francisco for 30-40 minutes, programming in Ruby with RSpec/Cucumber. Should be fun to “perform” and watch the other pairs as well. Looking forward to that session on Wednesday afternoon!

My fellow ThoughtWorker Pat Kua will be there presenting a workshop as well. I will try to brush up my (lately lazy) writting skills and publish some conference reports. And hope to see you all there in Sardinia!
