Legacy code projects struggle before coding even begins. Which features are implemented, where they are located, and at what maturity level, is often unclear. In short, a gap exists between the business domain and what is implemented in code.

In green-field projects we use Domain-Driven Design tools and patterns, so the gap does not happen. An additional set of patterns is needed when we start out with legacy code though. A set that extracts the knowledge from code, from git, from jira. With…

When it comes to Collaborative Modelling (CoMo), simplicity and adaptability are often perceived as defining strengths, but this notion of "just adapting on the fly" can be misleading. Many CoMo methods are deceptively simple, creating false confidence in their effortless adaptability across various scenarios. However, the high level of collaboration and intrinsic motivation required from participants demands meticulous preparation, especially when the goal is hard to pinpoint, politics are…

Domain-Driven Design (DDD) promotes flexible architectures built around bounded contexts and domain events. In contrast, industry blueprints like TM Forum’s Open Digital Architecture (ODA, www.tmforum.org/oda/about) push standard APIs and business object models for enterprise IT modernization. On this example subject, the talk confronts industry standardisation ideas with DDD principles: are such blueprints the ultimate domain-driven anti-pattern or a foundation for synergy between open…

Beim Analysieren und Zerlegen von Legacy-Systemen nach DDD sind wir auf Domänen gestoßen, die einfach in Subdomänen aufgeteilt werden konnten, und auf Domänen, bei denen es deutlich schwieriger war. Auch das Alter und der Entwicklungsgrad einer Domäne haben Einfluss auf unsere Möglichkeiten, gute Subdomänen zu finden und die Legacy zu modularisieren. Inzwischen können wir diese Unterschiede beschreiben und haben verschiedene Domain Patterns gefunden und benannt.

Zielpublikum: Architekten,…

My talk presents a practical case study of how we combined Domain-Driven Design (DDD) with a focus on specific quality scenarios of with Quality-Driven Design to create an architecture capable of evolving with our business. I'll share our collaborative modeling journey that brought together domain experts and development teams to identify proper bounded contexts, establish context maps, and define appropriate integration patterns. You'll see how we shifted from a technology-centric to a…
