This talk will start by examining how variability manifests in the delivery of our software systems, and the pain it causes us. It will also consider how it also offers access to the greatest possibilities software offers.

This talk explores how architectural qualities—such as scalability, composability, reliability, and observability—can be transposed onto social systems. By jointly optimizing both sides of the mirror, organizations can foster collaboration, innovation, and resilience.

In this case study, we will present the challenges our team encountered while applying DDD in a U.S. government agency that was not ready for DDD.

The text of the post on screen
"Create contexts in which options can be discovered, evaluated and selected.
These contexts themselves constrain the kinds, amounts and complexity of the things discovered." - @cyetain.com at #dddeu

Some serious Herbert Simon vibes during @cyetain.com closing keynote at #dddeu 2025!
About one hour ago I observed the reverse doorway effect, when leaving the room I remembered something that I couldn't remember at all while in the room.

Reading suggestion by @andrewhl.bsky.social at @dddeu.bsky.social, but I guess I am not going to buy a CD.
Maybe it comes with the CD player and loudspeaker and installation? 🤔

Splitting a domain when you have identified the different purposes is easy, says @ziobrando.bsky.social at @dddeu.bsky.social 💯
Couldn't agree more! It's the purpose that defines the system, aka it's system principle.

Just enjoyed "the most dramatic talk this morning" @dddeu.bsky.social presented by the 'High Elf' @julientopcu.com and 'Gollum' @josianchevalier.bsky.social about the journey to "The Grey Havens", intertwined with model tension heuristics and accidental design debt. 😍
Awesome #DDDEU 🥰
One of the best things of #DDDEU is the time spent with socializing, before, during and after every conference day 😍🫂
The third and final day of #DDDEU barely started and I already find myself struggling to find my way out of the beautiful mess.
Should I expose it, hide it, or detach from my models and try my executive's patience?
A big thank you for the morning keynote @dddeu.bsky.social
"Technical design: make the implicit explicit. Social design: make the undiscussable discussable" @settling-mud.bsky.social @johncutle.fish at #dddeu
Grateful for the chance to speak at @dddeu.bsky.social yesterday 🙌
I had some great conversations afterward, thoughtful questions and kind feedback 🙇♂️
Huge thanks to the @aardlingeu.bsky.social team for organizing and hosting such a fantastic event, and to everyone who joined the session!

"We have this mythical person in the DDD community: the domain expert" @settling-mud.bsky.social in the keynote with @johncutle.fish #dddeu

Huge conference screen with the cynefin quadrants and the text: convert complex problems into predictable, repeatable, orderly software
