El libro que llevo 25 años intentando no tener que escribir

"Hoy, cuando la última moda es el AI-assisted coding, sonrío pensando que los principios que aprendí hace diez años siguen siendo los mismos." — del prólogo, por una ingeniera que trabajó en el equipo

Durante más de dos décadas he explicado las mismas ideas a los mismos tipos de equipos. Equipos distintos, empresas distintas, contextos distintos. Y sin embargo, el patrón se repetía con una regularidad que ya no puedo ignorar.

Equipos talentosos. Equipos capaces. Tecnología razonable. Y aun así: la sensación de correr cada vez más fuerte para avanzar cada vez menos.

Lewis Carroll lo describió mejor que yo en A través del espejo: "Aquí, como ves, se requiere correr todo cuanto se pueda para permanecer en el mismo sitio." Durante años pensé que esa metáfora era exagerada. Ya no.

Parte del problema es cómo pensamos sobre el software. Decimos que lo "construimos", como si fuera algo que se termina y queda ahí. Pero el software no se construye. Se cultiva. Es un sistema vivo que crece, cambia y se degrada. Y los sistemas vivos necesitan atención continua, no solo construcción.

He llegado a la conclusión de que lo más honesto que podía hacer era escribirlo.

De qué va el libro

"Menos software, más impacto" tiene un subtítulo que no deja mucho a la imaginación: Cómo evitar que tu equipo colapse bajo el peso de su propio código.

La tesis central es incómoda: el mayor problema de la mayoría de los equipos no es que escriban código malo. Es que escriben código de más.

El software existente consume recursos continuamente, lo uses o no. Cada funcionalidad añadida, cada integración, cada decisión de diseño que se acumula sin revisión tiene un coste que no aparece en ningún roadmap pero que aparece cada día. Lo llamo el coste basal del software, en analogía al metabolismo basal de un organismo: el gasto mínimo para seguir funcionando. Y como el metabolismo, si no se gestiona, crece hasta consumir toda la energía disponible.

El libro recorre cuatro grandes bloques:

  • Fundamentos: qué es el Lean Software Development y por qué el coste basal es el concepto central que lo conecta todo
  • Los cinco principios: eliminar desperdicios, amplificar el aprendizaje, decidir en el último momento responsable, entregar lo antes posible, empoderar al equipo
  • Calidad sostenible: por qué la calidad no es el enemigo de la velocidad sino su única base duradera
  • Pensamiento sistémico: optimizar el todo, integrar Lean con XP y mentalidad de producto, y qué pasa si no haces nada

Son 192 páginas. Basadas en más de 25 años de experiencia en equipos reales: Alea Soluciones, The Motion, Nextail, Clarity AI. Con casos concretos, conflictos reales y errores propios reconocidos. El libro incluye también las perspectivas de ocho profesionales que han vivido estas transformaciones desde dentro, en distintos roles y contextos.

Para quién es (y para quién no es)

Este no es un libro para quien quiere mejorar su código de forma individual. Hay libros excelentes para eso y este no es uno de ellos.

Es para quien toma decisiones sobre qué se construye, qué no se construye y qué se elimina. Engineering Managers, Tech Leads, Product Managers, CTOs. Cualquier persona con responsabilidad directa sobre la capacidad de un equipo a seis meses, un año, tres años vista.

Si tu día a día es decidir prioridades, gestionar capacidad y negociar alcance, lo que viene en el libro te va a resultar familiar. Y probablemente incómodo. Esa es la intención.

Por qué ahora

Hay mucha literatura sobre Lean, XP y Agile en inglés. En español, menos de la que debería haber. Y casi ninguna que combine los tres enfoques de forma integrada, con casos reales de equipos que conozco de primera mano.

Además, el contexto actual lo hace más urgente. La aceleración que trae la IA hace que las decisiones sobre qué construir y qué no construir sean más importantes, no menos. Amplificar la capacidad de un equipo que ya construye demasiado no resuelve el problema. Lo acelera.

El borrador está completo. Ahora viene la revisión, la edición y la preparación para publicación. Si te interesa estar entre los primeros en leerlo, escríbeme: eferro@eferro.net

DevOps concepts and learning path

As Jez Humble said at leading a devops transformation DevOps is:
A cross-functional community of practice dedicated to the study of buildings, evolving and operating rapidly changing, secure, resilient system at scale. 
DevOps includes and enhance the ideas of the Agile Software Development giving a more end to end vision of the value stream for a technology-based company. And, you know, Every Company Is A Tech Company.




In summary, I think that DevOps should be the core of any technology-based company and the only option to reach/pursue the necessary business agility.


Main characteristics of DevOps culture:

  • Collaboration between development and operations (avoiding SILOs and conflicting goals).
  • Organize around the value stream optimizing for the flow efficiency (not resource efficiency). Learning to work in small batches.
  • Remove waste (Non-Value Adding Activities).  Of course, we talk about value from the customer point of view.
  • Build quality in.
  • Create fast feedback loops.
  • Maximize organizational learning (making safe to fail and learn).



Common practices:

  • Infrastructure as code.
  • Developers are involved in operations of the system (you build it, you run it).
  • Operations involved in the development from the beginning (introducing/facilitating specific, nonfunctional requirements to create a system easy to operate and monitor).
  • Automation (to avoid errors and to facilitate short iterations).
  • Continuous Delivery.

Books / Learning path:


If you are interested in learning about this culture and you like reading books, this is the learning path I recommend:


 

The Phoenix project: As a great and easy to read an introduction to Lean in an IT environment. (My review)


 

 The DevOps handbook: The complement for The Phonix Project that explains step by step the typical practices and the strategy to introduce DevOps. A short of practitioner’s guide.


 

Continuous Delivery: To learn the principles and technical practices that enable rapid and incremental delivery of high-quality, valuable software to our customers.




Accelerate: To understand how to build and scale high performing technology organizations creating this DevOps culture. This book is also an analysis of the data from the State of DevOps reports that give an idea about the importance of these practices.






 

 

 

Team Topologies: To have a common vocabulary and organize the different types of teams that suit the business needs. The recommended team organizations try to optimize for end to end flow.




If you are involved in any technology company, do you a favor and learn about DevOps... As the State of DevOps report indicates is the key to be a high-performance organization.

Book Review: Reinventing organizations





Reinventing organizations

A Guide to Creating Organizations Inspired by the Next Stage of Human Consciousness

by Frédéric Laloux

This is an incredible book that has had a deep impact on my thinking… It gives a great historical view of the different organizational model used by the humans and the correspondence of each model with each new stage of human consciousness.
It also explains how we are changing to a new stage and that a new kind of organizational model is appearing.
After giving this context and the explanation for each model, the book describes, this new "Teal" organizational model. The examples are very well documented and include a lot of details about the internals of the organizations selected.


The author also describes the environment from a human angle that allows this kind of organization to flourish… This new organization, the "Teal" organization, is optimized to deal with actual complexity.

An essential book for anyone interested in discovering the organizations of the future for this complex world.

A wonderful book.

Focusing my learning... (Js, Serverless, Aws, basic frontend)



I have some obsessive tendency to accumulate info/resources for learning (talks, presentations, blog post, books, podcast, etc).
From time to time I need to carry out an exercise to identify the things that I want to learn to complement my actual skills... This exercise helps me to narrow (temporarily) my scope for learning and gain speed, focus and motivation.

The process:


  1. I bring together a lot of topics that I am interested in (from languages, and technologies, to soft skills, and cultural topics).
  2. I classify each topic in several levels (my interest, my actual experience, level of alignment with my personal path/mission, etc.).
  3. I try to discard as many topics as possible... for example because I am already proficient or good enough. In these cases, I'd like to learn more, but I will not make any special effort.
  4. I select three or four topics.
  5. I remove mercilessly unrelated items from my list of resources (books, talks, blog posts, articles, etc...).  It is important to remove as much as possible because we don't have enough energy and if something is really important it will reappear in the future... :)




The results:


  1. Learning Javascript (the language). I will try to improve my Javascript knowledge up to a basic knowledge. Focused on the language itself and the most common execution environment (node and browser).
  2. Serverless. I see the serverless based architectures as the next step for a PaaS that force us to think in terms of events and create cloud-native designs. I think that this technology will be very important in the near future.
  3. Advanced AWS usage. In this case, I decided that even if I learned a lot about cloud technologies in my actual job I need to go deeper in AWS to really understand and gain more confidence.
  4. Frontend minimal stuff. I have developed from Linux kernel drivers up to cloud-native applications, but only a few times I needed to develop customer-facing apps (or at least in the actual frontend apps sense)... So my idea in this regard is to have the minimal experience with HTML5, CSS and the minimal amount of javascript needed to implement small SPAs.

I also take other actions to remove inputs for distraction:
  • Unfollow a lot of people on twitter (sorry, not enough time...).
  • Remove sync for email on my mobile.
  • And remove a lot of apps that generate push notifications.

This process also helps a lot with my impostor syndrome :)




And remember, when you buy a book, you don't buy the time to read it

Book Review: Nonviolent Communication: A Language of Life


Nonviolent Communication: A Language of Life


This great book explains how to have real and deep communication among humans. No matter how difficult the subject or how difficult the situation, this method proposed by the Dr. Marshall Rosenberg can improve our relations and communications by removing judgment from the equation and helping us to express our real needs.

This is one of the books that can significantly change your life… This form of communication is in our nature, but in most cases, due to our education (and upbringing), we have lost this skill, so the book is a method and a guide to recovering and developing it. Dr. Marshall guides us by using real examples and conversations from his workshops or from his experience as a mediator in difficult conflicts. He uses very clear language, it is not only very easy to read, but also very instructive.

For sure, this book is only the first step to discovering this skill and how deeply it can change your relationships. There are communities for practice, workshops and other books with more examples or exercises. Any skill requires practice.

In summary, a great book with a great purpose: to improve our lives, and relationships, express our real needs and help us understand the needs of others.

Book review: Team of Teams




Team of Teams: 

The Power of Small Groups in a Fragmented World 

General Stanley McChrystal, Tantum Collins, David Silverman, Chris Fussell 


A great book on how to generate a flexible and agile organization prepared to win in a complex world. The authors explain how they created a culture and an organization composed of a network of autonomous teams that at the same time have a shared purpose and a common context.
The most impressive thing about this book is that they described a real story of a deep transformation from a very difficult starting point:

  • A huge military task force 
  • A very solid command and control culture 
  • Several separated organizations 
  • Security risks about sharing information 

So no excuses… It can be done even in the most difficult contexts.

An indispensable book for anyone interested organizations that are adaptable, agile and prepared for this fast-paced, changing and interconnected world.

Note: An interesting podcast with one of the authors bosslevelpodcast interview McChrystal

Book Review. The five dysfunctions of a team

The Five dysfunctions of a Team

by Patrick Lencioni


This book helps to identify and solve the most common and important dysfunctions of a team. It helps to convert a group of related people working in an organization into a high performance team that works as a cohesive unit that can achieve much more than the individuals by themselves, or working as a group.


As an example, it uses one of the most important teams in any organization, C-level management. It examines the problems, possible solutions, as well as the process to make this change possible. The truth is that the tips, method and processes can be applied to any group of people who want to become a real team.


The first part of the book is written like a novel, very much like The Goal or The Phoenix project. The second part gives tools and describes the framework to create good teams.

Very instructive and easy to read book. Good for anyone interested in working or forming teams.

Discovered the illustrated version via Luis Artola :-)

Book Review: Drive (Daniel H. Pink)

Drive

The Surpising truth about what motivate us



I think that this book is fundamental to understanding how “work” is changing and what motivates us in a knowledge-work environment.

The jobs from the industrial age are disappearing and each day the number of jobs that require a lot of knowledge and creativity are increasing. So the tools and structures created for the previous era have no sense anymore. In fact I think that some of these tools and ideas are counterproductive.

This book explains human motivation very well and how science is discovering and validating these ideas. It also explains the differences between these ideas and the ideas that are the basis for the actual management techniques used by the vast majority of the companies. It also describes some examples of successful companies that use a more modern approach based on these verified ideas.

An indispensable book to understand the human motivations discovered through science: Autonomy, Mastery and Purpose.

It also describes some companies that have been successfully adapted and that use this knowledge about motivation to be more successful.

Indispensable for anyone interested in human relations, world environment and in how to improve our organizations.

I am very pleased to see that a lot of companies in my environment (software development, IT, etc) understand these principles and use this knowledge to generate a more “rich” environment.

Book highly recommended

In case anyone prefers a very quick summary you may also find interesting the following TED talk of its author:

Book Review: Designing data intensive applications

Designing data intensive applications 

The big ideas behind reliable scalable and maintable systems 
by Martin kleppmann


Important update: I am reading a more updated version, because this review is for a initial version with only 200 pages and the actual version that I am reading right now contains more than 500 pages, so take with a grain of salt.

Even if the title include the word applications, the book is focused in the different implementations of databases and other services/tools to maintain the state (cache, brokers, etc).
The book is very interesting to know the different implementations and the challenges faced by the developers implementing these kind of software (info distribution strategies, transactions, replication, and so on).
Personally, although the book helped me to remember certain concepts and learn new ones, it was not exactly the kind of content that I was expecting.

The book in general is interesting, but perhaps is more useful if you are working creating a database or something similar. For the enterprise application developer or for a system developer, although the book is interesting, it won’t add too much value.

In summary, good book if you are designing / developing infrastructure code to deal with state (distributed log, database, broker, etc).

Book Review: Antifragile



Antifragile

Things that gain from disorder



This is the best book I read this year… It was eye-opening for me, it make me change my point of view regarding working or dealing with complex domains and connect the dots between some ideas coming from different sources that I have pending to connect.
This book sometimes is not very easy to read and sometime it have some repetitive examples, but in general make easy to understand concepts that initially are not so easy so is a great work. And as I commented I think that the content is great, full of insights, takeaways and new point of views to deal with complex adaptive systems.

I think is a fundamental book to understand evolutive systems, their emergent behaviors and their characteristics. It also allow to identify very easy systems that in the beginning seems efficient but in fact are fragile, without any margin or slack and are doomed to be failure.

As a computer science and professional developer in this book I have identified lot of ideas from this field… For example, Alan Kay talking about objects as a biological systems, the Cynefin framework, abstraction, federation and microservices as presented by Tom & Mary Poppendieck, or the failure injection to improve a system (as in chaos engineering, netflix simian army).

A great book and lot of wisdom for anyone interested in complex adaptive systems, system thinking, etc...

    Book Review: The Innovator's dilemma



    Interesting book that highlights the importance of "growth/experimentation" mindset for creating products/services in a very fast changing environment.

    It is part of the base of other books as "The Lean Startup" from Eric Ries.

    It explains very clearly the difference between incremental improvements to a product and disruptive products or technology. Giving real examples and explaining the different approaches we can use to create disruptive products from diferent points of view (economic, management, motivation, etc)

    Good reading for managers trying to enter the world of innovation and startups. If you are already convinced that the "classic management" is not useful to create innovation, perhaps other readings can be more interesting (ex: The Lean Mindset or The Lean Startup).

    Anyway a great book.

    Book Review: Cómo Vivimos Y Cómo Podríamos Vivir

    This post is in Spanish because I read this book in Spanish. I also think that there is no english version of this book (even if the content is from some original speeches in English).


    William Morris

    Inspirador libro sobre al trabajo y el arte entendido como esencia del esfuerzo humano en un contexto en el que la productividad, el “crecimiento” y el consumo desbocado parece la medida del éxito. Podría parecer el mensaje de alguien abrumado por el ritmo de la sociedad actual, pero lo más gracioso es que es el mensaje de un diseñador textil, artista y revolucionario socialista en pleno apogeo de la revolución industrial.

    El libro me ha resultado curioso, muy inspirador, y con algunas ideas sobre las que merece la pena reflexionar. El contenido del libro son transcripciones de discursos que luego fueron publicados en diversas revistas socialistas de la época. Hay que tener muy en cuenta el contexto histórico y el formato de los escritos para que no nos impida ver el trasfondo del mensaje.
    En mi caso me ha impactado esa idea de crecimiento sostenible (no artificial) y arte como parte inherente del trabajo. Con estas premisas William Morris presenta la posibilidad de crear una sociedad en la que el trabajo sea parte intrínseca del desarrollo de cada persona en vez de un mal necesario para conseguir “cosas” cuya necesidad nos hemos creado artificialmente.

    El mensaje de Morris ha sentado las bases ideológicas para el renacer del movimiento de artesanía que se ve en varias disciplinas actuales (diseño, software, makers, etc). Por supuesto que no se ha alcanzado nada parecido a su propuesta, lo que no invalida la aportación de sus ideas y la necesidad de tenerlas en cuenta en esta “acelerada” sociedad actual.

    Hacia tiempo te no tenia este tipo de lecturas y aunque al principio me encontré un poco fuera de juego por falta de costumbre, enseguida conseguí sumergirme en su lectura y en una profunda reflexión. Finalmente lo he disfrutado mucho.

    Gracias Saski por la recomendación y el préstamo…
