XP Team Building

Let the team walk its path

Every team walks at its own pace and I haven't found a way to speed it up myself, I don't think there is one regardless of whether you are an external coach or a regular member of the team. Trying to push the team will screw up the work environment, the pressure may introduce interpersonal conflicts and severe damages in the quality of the product. I mean, people will do stuff they do know it's wrong because of the sense of emergency. On the other hand trying to pull the team away will give its members the impression that they are not trusted professionals, again causing problems among people and discouraging them from being proactive and willing to learn.
The only way we can help the team progress is to help them walk their own path, removing impediments along the way, answering questions when asked to do so.

I've learned that it's not possible to develop a software product at the speed that I'd like whilst mentoring people. I have to choose either to be a trainer or to be a developer but not both things at the same time because the goals are different. When working as a trainer the goal is that people learn effectively and the best way, for us humans, to learn is by making mistakes that let us learn from ourselves. As a mentor I must combine small theoretical explanations, recommendations and practical examples with time for people to practice and to make their own decisions. They must have the chance to fail and discover. If they don't recognize the failure my mission is to provide feedback and explain why is this or that a mistake and what are the consequences. Deep lessons are learned with pain - success is fantastic but it doesn't teach. However this style of mentoring takes a lot of time, it's probably the top most time consuming way. It's a company wide commitment, an effort for everyone.

Often companies ask us to join them for a new project that must deliver value within a tight schedule and at the same time they want to build up a team of XP developers with people that have never been exposed to XP. I must say this is completely impossible in my experience. If the quality of the product needs to be excellent and deadlines are tight, the best thing the company can do is to hire a seasoned high-performing XP team whose members have been working together for years. On the other hand, if the actual goal is to build up a team, this is an investment that lasts several years. According to my experience, a group of 6 to 8 developers become an XP team after 2 years of training, guidance, reviews and practice. It requires several training courses during the various stages of the transition, practical examples, guidance and moreover it requires small failures (hopefully reversible ones). People have to have the margin to fail and learn from their mistakes. During this period some people will very likely leave the company and some new people will join.

I know the word quality is too abstract, we don't have a definition for what quality is but I am actually talking about well-known maintenance issues. A common mistake beginners make is to write brittle and hard to maintain tests that with time impede developers changing or adding features. Those tests are eventually deleted. It's waste unless you consider this to be another stage in the team's learning curve.
Nobody writes perfect code anyway, every team makes mistakes so the point is not to aim for perfection. The point is to avoid or minimize the amount of things we do know are waste, basically because we have failed in the past.
Hiring seasoned external consultants means they won't make the same mistakes they did in the past although they'll make new mistakes. Every team is different as well as every project.
As a consultant I won't prevent the team from making mistakes when the goal is to train them, instead I'll try to keep the cycles small enough so that mistakes can be fixed soon and cheap. But it's up to the team to ask for feedback and review, my job is not to control the source code - it's to support the team!

In some situations it could be beneficial that a small group of experts write the "walking skeleton" with the first group of product features in order to define architecture, style and conventions that others can follow. It serves to explore risks and exposes an example that others can follow. There are several perils of this approach though. I'd be careful with it - sorry don't feel like writing about these drawbacks now.

Notes from Socrates 2015

The 5th Socrates Conference in Germany has been my first continental Socrates Conference (I've been to UK twice plus another one in the Canaries). What a mind blowing unconference! I got even more value from Socrates than I expected! this has been the biggest in size ever with almost 190 people. There were so many people that it felt like there were 3 conferences going on at the same time. Even in my last couple of hours in the venue I still found new faces, people I thought I didn't see before. Despite of so many people the atmosphere was excellent as usual and the organization brilliant. Congratulations to the organisers! everything was organised with German precision! Danke schön 😉
Unfortunately Andreas - one of the founders - couldn't join us but I am glad he is recovering well.

I've learned many things, met old friends (although I wanted to spend more time with them!) and made new ones.

I have to thank my friend Ivan (@istepaniuk) for being our host and guide in Amsterdam and for driving us to Soltau. Thank you Imo (@kabomi), Juan (@_jmgomez_) and Adrian (@eidrien) for your fantastic company.

Thank you Pierluigi Pugliese (@p_pugliese) for your excellent job as facilitator and the conversation/coaching we had during lunch time.

  • Twitter hashtag was #socrates15
  • Really like the idea of the world cafe on Thursday to get people thinking on what they would like to happen the next days.
  • There are so many proposals that is hard to remember some sessions when looking at the panel, that makes it even harder to choose sessions. Next time I'll write down in paper exactly the minimum and most effective sentences I'll need to present my proposal so that I'll just have to read when the time arrives. Talking to the mic is a bit unconfortable when not used to it.
  • I'll book more time to spend with my friends and specially with my colleagues.
  • In the sessions intended for me to ask questions, to be taught something or to have a discussion is not necessary to have slides but it's worth preparing the session. It could be a script, a few examples to discuss on, a set of questions... something to facilitate the session and an idea of what to achieve with it.
  • Some of the most valuable moments happen out of the scheduled time table or in those with a small group of people. Next time I'll plan to spend about half of each day out of the rooms, talking and coding with people or even coding on my own in places where others can see me and join.
  • I will propose maximum one session per day, then I'll feel more relaxed and free to change plans.
  • Sleeping enough is key to enjoy the event until the end, otherwise I am already a zombie at the end of the first day. Nightly discussions are super interesting, I'll probably oversleep in the morning at least one day to be fresh and ready for the night.
  • Socrates is an open space where I can go without any session prepared, people are so amazing that there will be for sure a lot of stuff to learn.
  • The idea of workshops on Sundays is brilliant we'll do the same in Socrates Canaries. I've learned many things on Sunday working on a walking skeleton and solved many doubts regarding DDD. Special thanks to Bardford (@gruebelinchen), Björn, Felipe (@felipefzdz), Martin (@md42), Dimitry (@dimitrypolivaev), Ivan and all the people that stepped in and out during the workshop.
  • It's the right time for our team to embrace ES6 and use it in the project we are starting from scratch. Thank you Wolfram (@wolframkriesing), Marco (@marcoeimrich) and Christian (fonzygruen) for all the insight and information. Thank you also for ES6Katas and Ramda.js - we're gonna use both. Thank you also for valuable resources like NodeSchool and the refactoring kata (refactoring to functional style using Rambda) proposed by Marco.
  • Property-based testing is definitely something I want to try. Thank you for the insight and opinions on when to use it and when not to use it, specially to Pawel  (@pawelduda) and Kuba.
  • The theory of type systems is super interesting, I would like to get the slides from Ivan (@ikusalic) and compare how Type Classes in Scala are different to generics in C#.
  • Informal discussions like "Developer Ethics" are perfect to be hold during lunch time. I'll propose topics for lunch time like in this conference, so that I'll know what to talk about with people I don't know but who share a common interest. Unfortunately tables were not big enough this time to join some lunch discussions.
  • I really like the metaphor of the power lifting in pairs to explain pair programming, thank you Houssam (@houssamfakih) for sharing your experiences along these years of practise.
  • I want to learn more about Event Sourcing and CQRS. This is the second conference where people recommend Event Storming and I haven't used it in a real project. It's on my to-do list.
  • Thank you Tobi (@tpflug) and Chris (@c089) for organising the Power Point Karaoke once again and the variants. Thank you Adrian, Pawel, Christian (@dertseha) & company for such hilarious nights. I plan to play the PP Karaoke on the New Year's eve with family and friends.
  • Choose the blue route in the GPS, not the red one - although Germany is beautiful.
  • 30 mins Gym + 30 mins sauna after the sessions is a must. German get naked in the sauna no matter if there are men and women mixed.

2014: Un gran año

Últimas horas del 31 de Diciembre de 2014. Para millones de personas es un día de celebración. Aproximádamente el 75% de la población cambia de año cada primero de enero siguiendo el calendario gregoriano, aunque solo unos pocos podemos hacer una fiesta. Para muchos es el último día de su vida, para otros es el primero. Según la ONU, más de 30 millones se encuentran desplazados a causa de conflictos armados y muchos de ellos están en plena guerra, luchando por la supervivencia. Muchos morirán de hambre y otros por enfermedad. Miles de millones de animales sufren el holocausto en las granjas y mataderos industriales para satisfacer a una minoría de los humanos del planeta. Y el planeta según diversas organizaciones está en el peor momento de la historia.

Sin ignorar todo lo que está ocurriendo aún hay margen para el optimismo, la esperanza y la gratitud.  Mi deseo es ser cada día más optimista y más féliz sin necesidad de amnesia, ignorancia ni indiferencia. Haciendo por los demás todo lo que esté en mi mano. Consumiendo de manera responsable.

La hoja de ruta consiste en vivir el momento presente con atención, agradecido por tantas cosas buenas que me suceden.

2014 ha sido el mejor año de mi carrera profesional desde que trabajo como independiente. Todo lo que podía salir bien ha salido bien. He tenido la suerte de visitar multitud de empresas y trabajar con gente genial. He tenido tanto trabajo este año que no voy a citar todos los lugares por los que he pasado y personas con las que he trabajado porque se me quedaría gente fuera seguro.  Me ha encantado ver trabajar a algunos colegas del gremio como Luis Fraile o Luis Ruiz Pavón y ha sido un placer descubrir a Carlos Bastos.

A principios de 2013 pensaba que debía centrar mis esfuerzos en el mercado extranjero, sobre todo UK y Alemania pero este año el mercado nacional me ha dado mucho más de lo que esperaba y he salido poco fuera del país. Prácticamente cada semana recibía alguna petición para formación o consultoría y he tenido varios encargos de desarrollo de producto a medida con los que me lo he pasado bomba. He conseguido programar tanto como quería. También he podido empezar a grabar los screencasts de programación que quería (y haré más).

Pero lo más importante son las alianzas que se han ido fraguando por el camino. Sin buscarlo estamos cerrando el año funcionando como equipos en lugar de ser un profesional solitario. Estoy encantado de cerrar el 2014 trabajando con mis compañeros Luis Rovirosa, Juan M. Gómez, Imobach Martín, Nestor Bethencourt, Modesto San Juan, Alfredo Casado y Fran Reyes. Y con todos los compañeros de AIDA (ahora cuento más). 

Luis Rovirosa está ayudandome con consultoría y formación en varios clientes, es un aliado con el que llevaba tiempo queriendo colaborar. Juan, Imo y Nestor estan desarrollando conmigo el editor de plantillas del popular MDirector, la herramienta de email marketing de Antevenio, un proyecto muy bonito. Alfredo, Modesto y Fran están conmigo y con el resto de compañeros de AIDA trabajando en un proyecto apasionante para el Grupo Domingo Alonso. Y hay más proyectos en camino. Por ello estoy en proceso de constitución de un SL, la que será mi segunda SL. Estoy ya cambiando la portada de esta web (carlosble.com) y pronto habrá mas fotos e info de todos.

Con semejante grupo de profesionales podemos atender toda la demanda que me llega y puedo estar tranquilo al delegar. Poder delegar sin preocupaciones, no tiene precio.

Cerrar el año trabajando para Grupo Domingo Alonso es una suerte. Se trata de una de las mayores empresas de Canarias aunque yo no la conocía porque los coches no me llaman la atención. Surgió una consultoría con ellos, en parte a través de nuestro amigo y maestro Jose Juan Hernandez de la ULPG y pude conocerles. Me quedé encantado con la calidad humana del equipo, sus valores, su energía y con el proyecto en sí. No tenía intención de proponerles colaboración para sacar adelante el proyecto pero cuando volví a casa y pasaron unos días me dí cuenta que yo quería trabajar allí y les mandé una propuesta. Es un super reto, la construcción de un complejísimo Dealer Management System. El reto es tan grande que necesitaba pedir refuerzos y para mi sorpresa, tanto Alfredo como Modesto y Fran lo dejaron todo (bueno, a sus parejas no!) y se mudaron conmigo a Gran Canaria para meterse en el proyecto. Llevamos dos meses de proyecto y cada vez me gusta más todo lo que conozco. El capital humano de AIDA (Aplicaciones Informáticas Domingo Alonso) es increible. En la fiesta de navidad nuestro compañero Alejandro Artiles se curró este gracioso vídeo explicando lo que estamos viviendo en estos comienzos del proyecto, al estilo "Stars Wars":

Por si fuera poco, en Junio de este año mi padre volvió a nacer. Ingresó en urgencias y los medicos dijeron que no sobreviviría. Un fulminante cáncer de cólon. Sin embargo lo ha superado por completo en muy poco tiempo. Mi padre cuenta la experiencia en su blog. Ha sido la mejor noticia del año, lo mejor que ha sucedido.

Este post es sobre todo para daros mil gracias a todos los que estais haciendo posible este grandísimo momento. Gracias a todos los que este año habeis contado conmigo. Ha sido un placer y estoy seguro de que viene mucho más por delante.

Gracias a Dácil por estar siempre ahí, por ser mi motor. Gracias a mi madre por cuidar de todos nuestros animales del refugio cuando yo no puedo hacerlo por mi trabajo. Este año, sin mi madre no hubiera sido lo mismo, no sé cómo lo hubieramos hecho.

Caramba! ya es 2015! Próspero año nuevo!

A week to remember in Barcelona

Last week was awesome, I went to Barcelona to run two training courses. Well, one of them was my yearly session at the Postgraduate on Agile Methods at La Salle (Universitat Ramon Llull). The first postgraduate in the world on Agile Methods. I explain eXtreme Programming, together with my good friend Rubern Bernardez,  during 6 days (3 weekends).

PMA 2013/2014

PMA 2013/2014


This has been my third year at the PMA and it's been really nice. The selection process for participants went very well thanks to Xavier Albaladejo and so the group was excellent. People have made an endeavor to understand the XP practices and the values behind. Even project managers, people that have been away from code for years, were test-driving the exercises in pairs.  The fact that decision makers come to the class and get to appreciate the benefits of clean code and XP is very important in my opinion.  Because they can encourage and tell developers later. In the group there were testers and developers too. The different mindsets together were very interesting when facing code. Enriching experience for everybody. Thank you all for this great PMA edition. Special thanks to Xavi and to Quim Ibañez for his kindness and support.


During the week, I gave one of my TDD training courses, this time open to the public. In general, public courses are more energizing than in-house, because people are willing to learn and participate. They have to pay for their ticket or ask their companies and that makes a difference. This time I got to know several members from the Barcelona Software Craftsmanship Community. The level in the training was very high, in fact, it was more an exchange than a teaching session. There were many interesting discussions and retrospectives whilst looking at the code in the projector.  It's been also very nice to meet old friends and observe how they have progressed over the last couple of years. Specially Manuel Rivero who has made an outstanding progress in his career and now let me learn from him.


TDD Training in Barcelona

TDD Training in Barcelona (open to the public)

This experience reminds me my first open course in Madrid in 2010, when I got to know people that are now good friends and that today, run their own training courses on TDD and clean code or lead teams. So I believe that we have started here a wonderful relationship and that we will cross roads soon again. There was magic in the air.

I have to say thank you to my good friend Javier Gomez for all the support and the hosting,  as the event happened in Ricoh Spain. In this kind of courses I get to know great programmers that usually end up being colleagues or collaborators at some point 😉

Coding dojo - Barcelona Software Craftsmanship

Coding dojo - Barcelona Software Craftsmanship


Thank you very much also to all the folks that came to the coding dojo that we had on Monday evening, hosted by Barcelona Software Craftsmanship, thanks to Manuel Rivero, Beatriz Martin and Jaume Jornet. In my opinion the community is very healthy in Barcelona, congratulations.

My experience at the IronHack


I am one of the lecturers/mentors of the first IronHack edition, a training program for people who want to become professional developers. My part takes only three days and it's been this week. Three full-day hands-on sessions on JavaScript, TDD and testing techniques. The experience has been fantastic for me.


During the class at IronHack

When I knew about this idea of training people with any background so that they become developers in only 8 weeks, I thought... shit man, how the hell are people going to learn and assimilate all the contents and concepts in such a short period of time? That's impossible! But I was invited as a mentor by Mauricio Morales and his energizing message made think that I wanted to know how this accelerated training academies works. So I accepted the invite to experience something new, to experiment and learn. And it's been totally worth joining the teachers team :-)

The best thing it's been getting to know the people. IronHack staff are great guys and the participants/students are brilliant. They are doing their best to understand all these new techniques and tools despite of their different backgrounds. People that progress faster take their time to pair up with the people that are struggling, helping them speed up the pace and learn. The people with less programming background are very patient and motivated. Well, all of them are very motivated, this is what is exciting in there.

For me it's been a challenge because I am used to train developers but not beginners. Some of the folks were developers but some of them were pretty new to software development.  And difficulties is what make me learn the most, so I've learnt important lessons that will help me out in the near future. Anyway I am quite satisfied with my work and specially with their effort.

Now, as you may imagine, this training does not entitle all the students to consider themselves senior software developers right after the end of it, it's just too short! But I don't think that is the objective. They are learning from passionate professionals that work every day in "the real world". One or two different guys like me every week. They are getting to know the best techniques we know, how we think and work so that they are learning from our mistakes. What has taken years for some of us is summarized in hours during the training. Internalizing them is going to take sometime to students but it's still faster than some traditional training methods.

I believe this concept is good even if it only serves to add some pressure on other training methods. We need better developers and providing different training alternatives sounds right to me.

If in the future I meet a single person from this fantastic group and she tells me that what we practiced in the class was  useful in her career, then my objective will be accomplished. If they write code with care from now, I'll be totally satisfied. Code for other human beings, not for machines which is what some people believe after other training programs.

I want to say  THANK YOU to the guys behind IronHach: Ariel Quinones, Gonzalo Manrique, Israel Guitierrez, Xavi Leal, Mauricio Morales and company.

And of course THANK YOU to the intrepid participants: Sergio Revilla, Daniel Bardaji, Daniel Castillo, Agustin de la Villa, Alejandro Dominguez, Daniel Cusan, Marta Fonda, Fernando Moreno, Ruben Kanna, Imanol Yañez y Jaime Muñoz.



2013-11-27 17.58.59

Tuenti office with my friends: Miguel Angel Garcia, Joaquin Engelmo, David Santiago, Imanol Yañez and Marta Fonda

And I visited Tuenti for my first time, finally!

Yesterday was a very intense day because right after the full-day session at the IronHack, I went to Tuenti offices (Madrid) to give a talk to software engineers.  Last week my good friend Kini and Jose Lorenzo sent my an email inviting me to do so. I didn't prepare slides because I didn't feel like giving another talk with slides I felt more like having a discussion. I just prepared a few ideas based on my experience and my point of view to start up the discussion. It was along the lines of professionalism, XP and specially practices like TDD and BDD. Fortunately people were participating in the discussion with a lot of interest. I am not very good at counting but I guess there were more than 50 people. Tuenti gathers some of the most talented developers in the country, not only Spanish developer but also from other countries.  It's a very nice place, looks  very cool as a place to work. I've been listening how good people are in Tuenti for a long time so I am glad I got to know people in person that I only knew from twitter and really enjoyed sharing experiences with them. I hope to meet this group more times in the future.

Case study: Audience Response

Wow, AgileTestingDays 2013 it's being awesome! I gave my talk today, a practical "live coding" session. Last week I created a real-time application to communicate with the audience so that when I am speaking they can tell me if they are understanding or if they want me to repeat ...
So we started off using this app on my session. Interestingly enough the session was about building the tool again. From Cucumber specifications, all the way down to the GUI and the hub (server).

You can find the actual code of the application here and more importantly, the process I followed to write it, because I checked-in the code on every green test so by looking at the diffs, you'll figure out how code evolved.
Unfortunately the wifi didn't work well so I couldn't really take advantage of the app. Next time I'll bring my own wireless router to create our private LAN.

In order to prepare the session, I rewrote part of the app again myself. In here you can find this second iteration, again with a test committed at a time. By looking at the commits you can follow part of what I did during my session. You can take the code and practice yourself from this particular commit, comparing your moves with mine ones to see what we can learn.

Find the business specifications of the app here and the step definitions (glue) in here.

Now, the session didn't go bad, but it didn't go as well as I'd like. I did quite bad with the timing.I would have needed 90 minutes rather than 45 to illustrate the process properly. When I was preparing the talk, I wrote the code on my own and it didn't take much time, but presenting it's a different story, I've learned that I need about twice as much time.

2013-10-31 01.24.06But I am satisfied because several people understood the process and got value from it. Next time I run this session, it will go much better. And you know what? I've been approved by The Code Cop! Look at this picture.


I'll be happy if you were attending the talk and can give me some feedback in the form of a comment in this blog. As a reward, one person out of the people commenting will be randomly selected and I will run a free 90 minutes session for her/his company (remotely, videoconferencing), doing this same exercise properly with Q&A session.

James Lyndsay and Bart Knaack from The Test Lab have used an instance of the app for testing purposes and people have found several defects. I am happy for that because I didn't do any exploratory testing or even took care of network failures or latency problems. Thanks for that guys!

This exercise will be part of my upcoming book on Agile JavaScript for Rich Internet Applications. I expect to have the book done in 2014.

If you want to have a look at the sample deployed app on Heroku, use these urls:
Load a page in the browser with this url (as a speaker).
Then load the page as the audience in other window.
Then just interact.

Thank you very much for all your support, I really appreciated you invested your time on my talk. If are there questions please let me know of find me tomorrow in the conference to catch up or hang out :-)

A week in the UK

Talking at SkillsMatter

Last week was very intense indeed. I gave my first talk at Skills Matter (video here).

BDD for RIAs with JavaScript - Skills Matter from Carlos Ble

I must say I am not content with my talk because my English was rubbish but on the other hand I am glad that it provided value to some attendees. That is why I did it. I am also glad because it gave me the opportunity to meet very nice people (we were having some chats before the talk, and afterwards in the pub). And I will do better the next time :-) I have learned several lessons.

First one, I will not give talks right after landing a plane. The fact that I could arrive late if the flight or the train was late, made me very nervous, I went running to the venue and it doesn't help to concentrate. I must fly the day before.

Second one, when I talk in English, I must have pretty much everything I want to say written in cards so that if I can't find the words, I can just read. My English is not too bad when I am relaxed but under pressure, it's much harder to find the words and pronounce. When giving a talk, I pay close attention to attendees, timing and the way I am expressing myself. All these concerns difficult my capacity to talk in English.
I'll be talking advanced English lessons with natives, aiming to get fluent some day. But in the meanwhile I must have the written speech as a backup.
When my friend Ivan Stepaniuk and I gave a talk in the Agile Testing Days last year, everything was written and it went better. Also the fact that we were two guys made it easier.

Third one, audience's feedback is different depending on the culture. When I talk in Spain I can clearly read faces and see if they follow me or not. But this time it was really hard for me to now if they were following me. I must not loose concentration regardless of my difficulties interpreting audience's feedback, but just keep going unless they actively ask.

Fourth, talking with braces is f***g annoying! :-)

If I keep practicing and taking lessons, with the help of a trainer I'll become better.

Participating in the SocratesUK open space

The following days I participated in the #socratesuk open space, organized by the London Software Craftsmanship Community.
2013-09-21 18.31.10

A great event in the countryside, an incredible venue.

It started with lightning talks and a fish bowl. The next two days there were talks, discussions and time for pairing with people. Pairing was the part I enjoyed the most. After dinner people used to meet in the bar to talk, drink and pair.
The last day we spent the morning hiking together along the countryside in a beautiful sunny day.

2013-09-19 16.23.52

Rachel Davies did an excellent job facilitating the whole event. And people were friendly and willing to share and learn

Having everything in the same place was very handy to meet different people. And the food was good. I've learned, shared, and met very nice people. It's been totally worth participating.

Thank you very much to the organizers and all the participants.
2013-09-22 10.26.53

I'd like to participate in Socrates Germany next year as well as Socrates UK.

Several people said we must organize Socrates Canarias. What do you think? shall we? :-)

¿Agile Spain o España Agil?

No puedo decir que esté contento con cómo lo he hecho en la organización de AOS2013 y no me gustaria que este post fuese punto de discusión sobre lo ocurrido en AOS. Para eso esta la lista de correo. Roberto Canales ha escrito también un extenso post sobre su experiencia y he comentado en él.
La organización sabemos que el efecto sorpresa con el idioma no estuvo bien y que fallamos en la comunicación. Tambien sabemos que Yeray y yo no habiamos preparado bien el discurso de apertura y que los nervios nos jugaron una mala pasada. Ya le he pedido disculpas a Yeray. Solo puedo disculparme por la parte que me toca.
En lo positivo de esta primera experiencia internacional, queda que eBay se ha interesado por varios desarrolladores canarios, y que al menos uno, ya está iniciando el proceso de entrevistas. De hecho Ben, el jefe de desarrollo me contó que estaba impresionado con la calidad de la gente aquí. No sabía que hacíamos estas cosas. Ni siquiera Sergio, su compañero español que emigró ya hace unos años a Londres.

Ahora quería compartir con los lectores de mi blog ideas que llevo pensando hace ya tiempo.
¿Está evolucionando la comunidad Agile Spain? ¿Hacia donde debe ir? ¿Estamos mejorando continuamente?

En los ultimos meses estoy viajando por Europa conociendo mucha gente interesante en conferencias y con la suerte de estar haciendo clientes fuera. Y estoy encantado por esta suerte, por las ayudas que estoy recibiendo. Estoy aprendiendo y tambien aportando, compartiendo.
Y me he dado cuenta que en practicamente toda Europa, los eventos de IT, se hacen con el inglés como idioma oficial, porque asi puede participar mas gente. Algunos lo hablan
mejor, otros peor, pero nos entendemos aunque sea a veces con gestos y generalmente la gente es muy tolerante y respetuosa cuando ven que uno está haciendo el esfuerzo de comunicarse.
En parte ha sido por obligación porque en España la cosa ya no me va tan bien como antes. Los clientes están dejando de apostar por la calidad (que es una de las cosas que la agilidad aporta), estan tirando los precios y contratando menos.

Creo que en España no le estamos dando la oportunidad a los demas profesionales del habla no hispana, a que vengan y nos cuenten lo que saben. Ni tampoco tenemos nosotros la oportunidad de contarles lo que sabemos.
Estoy viendo que mucha gente interesante y que nos puede aportar cosas, se está marchando del país (no diré nombres pero hay unos cuantos que conozco de primera mano), se nos está fugando el conocimiento. Y es bueno para ellos pero es malo para los que se quedan.
Estamos perdiendo oportunidad de crecer y mejorar.

Paises emergentes como Polonia, donde los desarrolladores tienen buena formación, se están abriendo a hablar inglés y están consiguiendo que empresas interesantes de países con fuerte desarrollo tecnológico les conozcan. Y esto no solo se traduce en puestos de trabajo interesantes sino que tambien es el inicio del cambio cultural. Que las empresas extranjeras se instalen allí hace que las empresas locales tengan que empezar a plantearse si su cultura laboral es adecuada. Es al menos un punto de reflexión para empleadores y empleados locales.

Creo que muchos queremos que la relación entre empleadores y empleados sea mas sana en España. Me parece que ahora está un poco pervertida en algunos entornos. Pero no tenemos ejemplos cercanos de otras formas de trabajar. Si no ves otros ejemplos, es dificil aprenderlos y cambiar. ¿Qué pasaría si nos abriesemos al mundo?

Que todo el mundo hable inglés en este país, es totalmente imposible. Ni siquiera se si sería bueno. Pero que las personas que trabajamos en software, en IT, no podamos comunicarnos en inglés, nos pone en desventaja. Todos los libros técnicos se escriben en inglés. No recuerdo que ningun castellano parlante haya inventando ninguna nueva técnica de desarrollo. Siempre lo importamos. Vale que luego lo aprendemos y puede que lo mejoremos, pero la tendencia la va marcando el mundo de habla inglesa. Entonces si no puedes con el enemigo, únete a él, ¿no? De hecho cuando le vas conociendo ves que no es el enemigo, que quieren que seamos amigos :-)

No debe ocurrir que por querer abrirnos, deje de entrar gente nueva del país a los métodos ágiles. Es decir, no cerrar puerta a quien definitivamente tiene problemas con el inglés. Y no dejar de hacer divulgación en castellano. Pero al mismo tiempo abrir las puertas a los de fuera.
Creo que ahora mismo no tenemos ninguna puerta abierta para ellos. Conocen del buen hacer de los españoles que han emigrado. Y muchos de esos no van a volver. Y cuando vuelvan, muchos querran que nos abramos para traer lo que conocen que es bueno ahí fuera.

Creo que es una oportunidad para que encontremos más y mejores ofertas de empleo. Para mezclarnos más y no llegar a ser endogámicos. Y el momento es ahora, que vivimos una crisis de valores y económica, una etapa de transición que nuestra generación no había visto antes.

Yo sigo el trabajo de ir dándome a conocer fuera y buscando colaboraciones con gente de otros países. Para aprender más, para compartir más. Buscando la manera de asistir a formaciones con los autores de los libros que leo. Y tengo ganas de ayudar a cualquiera que esté en esa línea. Estoy contento porque ya he podido aportar mi granito de arena y alguno de mis amigos ha encontrado fuera un trabajo que le ilusiona mucho. Que piensa que le trae crecimiento personal y profesional. Por supuesto mérito suyo pero estoy contento de haber podido poner en contacto a gente.

La comunidad española me ha aportado muchísimo en los años anteriores y siento que debo aportar yo tambien todo lo que pueda. Ahora mismo me da la sensación de que está estancada. Nos preguntamos por qué la gente que lleva tiempo ya no va al AOS ni a la CAS. Y a algunos ya casi no se les ve el pelo por España. Afortunadamente aparece gente nueva y con ganas, pero desaparecen algunos de los que nos pueden enseñar mucho. Y como he dicho, dejan de venir otros que no saben hablar español.
Me gustaría echar una mano a que demos el siguiente paso. Y para mí el siguiente paso es abrirnos al mundo.

Mi propuesta:

- AOS y CAS totalmente internacionales. Durante al menos unos primeros X años de transición, que haya tracks en español para que quien no quiera o pueda hablar en inglés se pueda expresar. Es más, que haya tracks en Euskera si se hace en Euskadi como la próxima CAS. Es la lengua materna de muchos posibles asistentes. Para que seamos totalmente tolerantes y no le cerremos la puerta a nadie. Pero que el evento sea totalmente internacional.

- Que siga habiendo eventos en español en todas las comunidades locales para hacer divulgación y que no deje de venir gente nueva. Tenemos coding dojos, coaching dojos, charlas, etc... y esta muy bien que sean en español.

¿Qué significa hacer el evento internacional? Que el resto del mundo se crea que de verdad es internacional. Y que les apetezca venir. El twitter oficial debe publicar siempre en inglés. Adicionalmente se puede crear otra cuenta de twitter en español pero yo descartaría esa opción. La web debe estar totalmente en inglés. Buena parte de la organización del evento se tiene que defender con el inglés hablado para atender a los que vengan.
La entrada del evento (CAS) tiene que tener un precio suficiente como para poder pagar los gastos de viaje, al menos a europeos. En el caso del AOS es gratis (pensamos que deberia cobrarse simbolicamente algo como 20 euros para evitar los problemas de plazas que hemos tenido).

Esto significa que la entrada seguramente sería más cara que en la actualidad. Y hay muchas formas de interpretarlo. A mi me gusta verlo como que aún así, me sale mucho mas barato ver a speakers internacionales aquí, que ir a verlos a Londres, pagandome viaje, estancia y un precio de entrada mucho más caro.

Mi forma subjetiva de verlo es que esto es abrir puertas nuevas, sin cerrar otras.

Yo me ofrezco a esforzarme por traer sponsors y speakers de otros países y a ayudar en la organización con mi inglés de andar por casa. Suficiente para entenderme con la gente. Y espero que cada día mejor.

Jorge Uriarte me comentaba que la CAS de este año es internacional porque traen varios keynote speakers de fuera y se permiten charlas en ingles. Pero las comunicaciones (twitter) se están haciendo en español y la web está en español (aunque también está inglés). Los eventos internacionales no tienen la web en varios idiomas.
Porque el espíritu no es que se forme el grupo de los extranjeros por un lado y el grupo de los españoles por otro, y que no interactúen. El espíritu es que el idioma oficial del evento sea inglés.
Dar entender a la comunidad internacional que les vamos a tratar bien, que se van a sentir igual que en Bélgica, Alemania, Holanda, etc...
Digamos que los tracks en español y en otros idiomas regionales deberían gestionarse de otra manera. O tal vez cómo hace la comunidad Gnome a veces, que tienen el evento español un dia antes o despues y luego el evento internacional. Es decir, que no se quite la oportunidad pero que desde fuera no quede sensación de que hacemos dos grupos. Más que nada porque fuera hay muchos eventos con los que competir y para que vengan, los que hagamos aquí tienen que resultar realmente atractivos.
De hecho será bastante dificil hacerla atractiva para los de fuera, es todo un reto.

No será fácil ir en esta dirección, no será sin críticas, pero hay mucho que ganar y pienso que, poco que perder. Siempre y cuando las comunidades locales sigan haciendo trabajo de divulgación.

Después de llevar años en difernetes comunidades, desde los grupos de usuarios de Linux, pasando tímidamente por Gnome y Mono hasta la comunidad ágil, se que este tipo de opiniones crean polémica pero mi intención no es seguirla ni dedicar mi energía a ello. Es ayudar en lo que creo que nos toca hacer ahora.

Bueno, ya he parido este pedazo de post. A por unas birras ahora. Gracias por leer :-) Comentarios educados son siempre bienvenidos.


The best coding dojo ever


I've got goosebumps on my arms most of the day. And it doesn't happen very often. This is the most emotional coding dojo I've ever facilitated. It's been in Gran Canaria, at the Universidad de Las Palmas de Gran Canaria (EII ULPGC).

The last day in college for some students, where many of them were thinking of their uncertain near future. Asking for recommendations and expressing many doubts.

More than 50 people coding together for more than 8 hours, in an incredible atmosphere.



How did we get here?

There is only one book on TDD in Spanish so far. Published by my friends and me back in 2010, under the creative commons license. Creative commons is like a virus for this. One year ago a real master, Jose Juan Hernandez (@jjhernandez) decided the book was nice to teach his students how to write clean code. We didn't know each other. In fact I didn't know the book was being used at the University. Jose Juan has been coding since 1985 and I do believe he is a software craftsman, now that I've seen him coding and teaching.
A couple of months ago he contacted me  see if I could give a talk to his students, about TDD in the real world™ and the encounter was excellent. The coding dojo proposal came along right after that.

Why has it been so good?

Guillermo and I

Several factors in here. Jose Juan has been teaching TDD, Refactoring, Patterns and Clean Code to his students the whole year. No only the practices but the values. This is the reason we believe he is a master, because his students have embraced and internalized his values and principles.

  1. So about 30% of the students were familiar with the techniques, and we asked them to pair up with those not exposed to automated tests and example driven design before. And they explained everything to others with passion. 
  2. In a regular coding dojo the facilitator does not necessarily teach. Her goal is facilitating. In this case though, we've been teaching people, so it's been half of a training session. With direct feedback on their work, based on our experience.
  3. We were 3 guys facilitating: Guillermo Pascual (@pasku1), Jose Juan and me. And the sinergy it's been huge.
  4. Everyone was absolutely willing to learn and share. Passionate people, warm and friendly.
  5. It's been a total win-win event. We (facilitators) have felt very useful and appreciated, it's been fulfilling. Some people have discovered a new way of understanding their careers, and what "caring about code" means.
  6. The retrospectives following every iteration were very participative, people were able to discuss among them.

What's next?

  • This is a milestone in the Canary Islands software development community, I can feel it. Something is changing...
  • Let's keep on practising together. The AgileCanarias community is growing and it's a good starting point  o meet new people and learn new stuff. The Tenerife group is kind of mature and stable now, let's do the same in Gran Canaria. And let's join the two groups for dojos and local conferences.
  • We have the Agile Open Space this year in Tenerife. Join us, it's a great opportunity to discover more.
  • Now you know there are different ways of writing software. Keep on learning, it's a never ending path.
  • When is the next coding dojo, who will organize and facilitate it? :-)

I want to facilitate a dojo, what should I know?

  • Manage people's expectations. In general a coding dojo is not a training session. Be honest with participants and help beginners as much as you can. Otherwise they'll be scared, run away and take a wrong idea about what it is.
  • A dojo is a space for innovation, try different things all the time, you don't have to follow the manual on the go. Just use your imagination and empathy.
  • Ask someone experienced to facilitate it before doing it yourself, if possible.
  • There is an interesting new book on this by Emily Bachehttps://leanpub.com/codingdojohandbook (haven't read it yet), foreword by Uncle Bob Martin.
  • Check out this video by Emily Bache: http://www.youtube.com/watch?v=yao5XLJqogQ


  • Jose Juan and Guillermo Pascual.
  • All the participants, of course. Without them, there is nothing to do.
  • Jorge Castellano for his pictures and video. Pictures will be uploaded soon here. Jorge already uploaded some pictures to twitter. Just search for the hashtag #dojoULPGC
  • Fran Santanta for his support and organization. Fran brought journalists from local newspapers and TV, apart from the food and everything else.
  • Mario Hernandez Tejera for his company, hospitality and sharing his interesting/wise thoughts.
  • All the colleagues who work with Jose Juan for his support and energy.
  • JM Beas, Xavi Gost and other folks from Agile Spain, as they introduced me to coding dojos.

This is the related thread in the AgileCanarias mailing list.

Wow! Agile Dev Practices 2013

So exhausted after the conference

Oh man, what a conference, I am just destroyed as you can see.

AgileDevPractices 2013 has been the first edition of an excellent conference. It was a big surprise for me when Jose Díaz from Diaz & Hilterscheid asked me to select the talks from the many proposals received. I was also responsible for the major part of the program. I didn't choose the keynotes and some other talks. Fortunately the conference has been very successful in my opinion, given that it's the first edition.  I have learned a lot and most importantly, I've met incredible people.

I landed in Berlin on Sunday to have dinner with my good friend Vicenç García-Altés, enjoy Potsdam's beer (Potsdamer Stange) and get ready for my workshop on Monday. The workshop went very good thanks to the energy and effort of the attendees.

Improvised theater

The speaker's dinner on Monday was very nice. It was close to the hotel so we saved a lot of time that was used for hanging out. I remember very interesting and fun conversations with many speakers. Back in the hotel's bar conversations kept going till midnight.

Thanks Kishen and Ellen for the pictures!

The dinner on Tuesday was very special too. Two awesome actors performed theater in front of us improvising the scenes based on notes written by us (the audience). I was specially lucky because they asked me to participate on a particular part. I had to move my arms and hands as if they were his. I had an incredible time over there in the stage, a lot of fun. I could have been performing for a long time. This man made it sooo easy for me to move.

The food and wine was lovely. People were willing to meet new people and jumping from one table to another to join conversations. Everybody was very opened to have conversations about business, practices, experiences or just funny jokes. This has been in my opinion the greatest point in this conference. Everyone got the chance to do a lot of productive networking.

There was no planned activity for Wednesday evening and a bunch of us run a coding dojo with JavaScript following the randory style. After that we went to a Russian-Italian-YeahWhatever restaurant where I almost pee in my pants because of the laughs, but this is something I better tell you in the next conf.
Having no planned activity on Wednesday was a great opportunity. The day after, during the lunch time, Vagif Agilov and Gaspar Nagy facilitated a very interesting BDD refactoring dojo, again as a non-planned yet excellent activity.

eBay has been one of the sponsors this time. They had a stand with very kind people, muffins and stickers and were there looking for talented agile developers. This is another good example of the many benefits one can get from attending this conference, ... exciting career opportunities! If you practice BDD/TDD regularly along with other XP practices and have also experiences with other agile methods, contact me and I can forward you to eBay for their teams in London or Berlin.

All the talks I attended to, were good for one reason or another. There were a few talks where the talk itself wasn't very good but then the questions and discussion made them very interesting. They keynotes were astonishing. I specially enjoyed the keynotes by Peter Saddington, Ellen Gottesdiener, Papa Chris Matts & Olav Maassen, and Pawel Brodzinski. And I really appreciated the fact that all of them got the time to hang out with me and others. It was not that they came in just for their keynote and run away right after. It was great talking to you guys! 

All slides will be send to attendees soon. Some speakers have also published them, just search for the hashtag #agileDevPrac on twitter.

Can we do better next time?

Don't take me wrong, the conference was worth every single hour and penny. In fact, I feel that I need a week's holiday. However, we are agile, aren't we? And so now that the conference has finished is time to think retrospectively aiming to improve future editions.

Talks in the program were tagged with the level (beginner, advanced, expert). Some talks didn't match the tagged level according to attendees. I believe the level was defined by the speakers themselves but I can't ensure that in all cases. Considering that AgileDevPractices gathers top level experts from all over the world, as an attendee, I expect an advanced talk to tell me things that I (as a practitioner) can understand but still be innovative, teaching me something new. For an "expert" level session I would expect the speaker to treat me like an expert in the subject, meaning that he/she is bringing cutting-edge stuff. If I have to be selecting talks for next editions, I will ask speakers to justify why talks are tagged with "advanced" and "expert" levels.

The second thing we could improve are talks titles. I asked several people why did they choose the talks they attended to, and most of them said they just read the titles, not the descriptions. So titles are very important and they must be self-descriptive (like good code). If I have to be selecting talks for next editions, and I find a title which seems controversial or hard to understand, I will ask speakers to justify the title or change it. A speaker might be tempted to write an appealing title for her/his talk to grab the attention of the potential audience. However, for such an important conference I would ask for honest, clear and concise titles, rather than for marketing strategies. I don't say this happened many times in this edition though.

Last thing I remember we can improve is handling last-minute program changes. This time there were several speakers that couldn't come eventually so the printed program was outdated. The website was updated and there was a big printed and updated time table in the lobby, but still I felt some confusion sometimes. I think we can probably use a mobile application next time to keep everyone updated using phones.

I am wondering now whether it is possible to make the last day as energizing as the first one, because some of us were really tired at the end. Some speakers told me they prefer to talk in the first day rather than in the last one. How can we work around this? Any suggestions?

Thank you very much to all of you!

First of all, a big thanks to Jose, Madeleine and Uwe for their huge effort and the incredible opportunity they have given to me.

Second, to all attendees and speakers. I have met so many nice people that I am not going to write names in here, to avoid missing any of them. Because every single conversation has been important and fulfilling for me. I expect new professional collaborations to emerge from this encounters.

Hopefully I will see you in the Agile Dev Practices next year! :-)

If you write a blog post about the conference, please let me know, I'll be happy to add a link here. Posts published so far:


As I told to some people in Potsdam, remember that we are organizing an open space in the Canary Islands in June. It's a free community event. The perfect excuse to visit the canaries for holidays with you family. We are planning leisure activities. It starts the 21st, but in the afternoon, so you can still attend to the Test Automation Day in Rotterdam the 20th, and fly to Tenerife the next day :-)  In case you want to know who is already planning to attend and show others that you are participating, join this list.

See you soon!
