Case study
4 years on, still in production.
Major European retailer — Search & Publication domain. 70 people, 6 sub-domains re-segmented without ever freezing delivery.
- 01
The problem
A 70-person domain, 6 tangled sub-domains, blurry boundaries and 5 years of accumulated organisational debt. The product roadmap was stalling.
- 02
The approach
Wardley Map, Event Storming then Team Topologies — map value, surface the real boundaries and re-segment the teams. On-site, with them.
- 03
The outcome
6 autonomous sub-domains, clean boundaries and an organisation still alive in 2026 — four years later.
70 people onboarded
6 sub-domains redefined
3 months with zero delivery freeze
4 years and the org still holds
1 monolithic 70-person domain → 6 autonomous sub-domains, still standing 4 years later.

A great training, even for someone who isn't a developer. Lots of solid practices for code and architecture design.
Thank you for this day — it gave us a clear overview and a step back on software architecture practices.
The course was both theoretical and hands-on with concrete examples.
