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.

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.

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...

Know the Flow! Events, Commands and Long-Running Services

Featuring Martin Schimak

Strategic design does not stop at defining boundaries around business capabilities" - it should reach out for truly smart endpoints, emphasize autonomy and the need for more coarse-grained and asynchronous APIs. The long-running services behind such APIs feel responsible for their business...
