#domaindrivendesign — Public Fediverse posts

A year ago today, @roundcrisis, @ahl and I published the first episode of Stories on Facilitating Software Architecture & Design. Yesterday episode 27 went out. We've kept it going every two weeks since.

We didn't start it to publish content. We started it because the work engineers are being asked to do is changing, and most people are working that out on their own.

Kruglanski's work on cognitive closure describes this pull. He wasn't writing about software boundaries. The pattern is the same.

Holding the discomfort is only half of it though. Hold it too long and the group is just tired. The other half is reading when the not knowing has done its work and closing there. That balance is a skill, and it gets better with practice.

Anyone can pick it up. What doesn't work is assuming someone will.

Subdomain, bounded context, service. Three different boundaries, drawn by different people, for different reasons.

A bounded context is a language boundary. A service is a deployment boundary. Picking one and assuming the other two came for free is where most of the pain starts.

@selketjah and I are speaking about this at KanDDDinsky, Berlin, 14 to 16 October.

I'm speaking at KanDDDinsky 2026 in Berlin this October.

KanDDDinsky is one of the few conferences where the hallway conversations are as good as the ones on stage. That isn't an accident. The whole thing is set up so practitioners learn from each other rather than sit and listen. Working software, real problems, no vendor pitches.

A lot of this year's programme deals with AI in business software: what it actually gives us, and what it costs us. Both parts matter and both get discussed honestly. If you build business software for a living, this is your crowd.

14-15 October, Park Inn at Alexanderplatz. Early-bird tickets are 800 EUR until this Friday, 31 July. After that they go up to 950 EUR.

🧩 „ECST-Event“, „Domain Event“, „ECST“: diese Begriffe fallen in fast jeder DDD-Diskussion, und erstaunlich oft meint jede:r etwas anderes damit.

Christian Stettler räumt auf: ECST ist keine Event-Art, sondern eine Eigenschaft. Ihr Gegenpol ist die Event Notification, nicht der Domain Event. Was oft „ECST-Event“ heißt, ist eigentlich ein Replication Event.

I’ll be there! Not giving a talk, alas, but always up for chatting or maybe playing a board game? 🤔 😁

The conference is full steam, and Zsófia Herendi and I will have our hands-on in 3 days. If business value and org design are topics that matter to you, join us at "From org chart to designed organization: making the invisible visible with business models and teams" hands-on lab!

And here the talk on Who Is Actually Making the Architectural Decisions Right Now? Facilitating Architecture in an AI-Accelerated World:

Zsófia Herendi and I will be running a hands-on lab at DDD Europe in Antwerp on
June 12.

The premise: you can't design teams without understanding how the business
creates value.

We'll connect Business Model Canvas to Team Interaction Modeling. Practical
heuristics that you will discover by working with your peers!

This is not a slideshow. A lab where you will share insights with others!

I’m not only presenting two talks (one is a game, guess what it is), but also thrilled to do a workshop on my current passion: #EventSourcing and #DomainDrivenDesign #Java

An alle #DDD und #BA und #RE Enthusiasten - das ist sicher etwas, was für alle interessant sein wird. Wie kann #DDD einer #LLM / #AI helfen, bessere Ergebnisse zu erzeugen? Genau das werden wir diskutieren!

So how do we assess whether the code AI produces actually reflects the model we need? That is hard enough for people. How does an AI know when the model is shallow?
