Hands-on: Master your Domain with Domain Storytelling

Featuring Henning Schwentner

Domain-driven design practioners want to identify bounded contexts and work out ubiquitous languages. Domain experts, however, often work together across contexts. The boundaries that shape your software systems must therefore not become borders that segregate people. DomainStorytelling helps you...

Stability and Change in Bounded Micro-Worlds

Featuring Jenny Quillien

Domain Driven Design is not particularly interested in simple problems of only one or two variables (tackled decades ago in the banking industry with the routinization of transactions). Nor is it particularly interested in problems of probabilities and statistics (tackled decades ago in the...

Keynote - Interviewing Domain Experts: Heuristics from the Trenches

Featuring Cyrille Martraire

Deep conversations with domain experts and careful attention to the language are central in software development and in particular in Domain-Driven Design (DDD). However, it takes many years and many failures to get better at this game.

Domain-Driven Dependencies

Featuring Cyrille Martraire

Dependencies come in many forms, from binary libraries to JSON contracts for example. While they are necessary to build complex systems, dependencies are also the cause of a lot of headaches, and learning how to better deal with them makes your life less miserable in the long run.

Don't Ask, Don't Tell the Virtues of Privacy by Design

Featuring Eleanor McHugh

You live in a world of poorly protected persistent data silos, the digital equivalent of a rusty tin box tied up with string and buried in a somewhat disheveled flowerbed. The owners of these silos hoard a bewildering array of personal data on everyone who interacts with them on the off chance...

Simplicity versus Simplification

Featuring Alexey Zimarev

You often hear that DDD is hard. People are trying and failing, complaining over increased complexity, which gets out of control. In fact, despite many complains that accidental complexity is overcoming the domain complexity, often this is not the case. Developers tend to over-simplify business...

Keynote: Design Heuristics

Featuring Mathias Verraes

Software design principles aspire to be universal. And yet, when you create software, you sometimes intentionally violate principles.

Keynote: Joys and Pitfalls of Collaborative Modelling

Featuring Alberto Brandolini

Modelling together can be a bliss, or it can turn into a painful experience. Shifting from an individual activity to a shared, collaborative one will expose thinking habits and fallacies that play a surprising role in our design process.
