Abstract

Starting a new project from scratch with a clean slate is one thing; tackling legacy systems with chaotic architectures is another. Many teams inherit systems described as “Monoliths” or “Big Balls of Mud,” and this workshop focuses on how to bring order to such challenges.

Who should attend?

This workshop is created for software developers and software architects. You already have an understanding of fundamental DDD concepts like strategic design, tactical design, and ubiquitous language.

Learning objectives

Participants will learn how to evaluate their current systems and identify steps to introduce—or restore—structure. After an introduction to key principles, the workshop will explore three levels of transformation: tactical, socio-technical, and strategic. The Modularity Maturity Index (MMI) will guide teams to determine their best path forward, starting with a focus on understanding the domain. Using Collaborative Modeling, attendees will gain actionable insights to design a clear and future-ready architecture.

A mix of foundational theory and hands-on exercises will equip participants with practical strategies to address common challenges, such as BBOM architecture, anemic domain models, and disorganized teams. By the end of the workshop, attendees will have a catalog of proven refactorings, actionable heuristics, and concrete tools to immediately evolve their own projects.
