The DDD Dream? A Domain Expert Full-Time in a Mob 🚀

17 minutes

Is the ultimate Domain-Driven Design (DDD) dream having a domain expert fully embedded in a Mob? Or does it come with hidden trade-offs? In this thought-provoking episode of the Mob Mentality Show, we explore the benefits, challenges, and real-world experiences of having a domain expert (or product owner) participate full-time in a Mob—not just as a consultant but as an active driver and navigator.

🔹 What We Discuss in This Episode:

✅ Quick Access vs. Full-Time Participation – Is it better to have a domain expert available when needed or fully immersed in the Mob?

✅ Real-World Stories – Chris shares insights from four product owners with different availability levels and how that impacted effectiveness. Austin reveals what happened when a domain expert became a full-time Mobber.

✅ The Pros of a Full-Time Domain Expert in a Mob – Faster decisions, deeper collaboration, improved knowledge transfer, and more!

✅ Natural Synergy with DDD – How DDD experts seamlessly jump into code naming, improving model alignment.

✅ Testers & Domain Experts: A Similar Integration? – The parallels between merging testers into a Mob and embedding domain experts.

✅ Potential Downsides – Does being in the Mob full-time reduce a domain expert’s ability to stay ahead in their field?

✅ Autonomy & Learning Diversity – How does this setup impact team growth and decision-making?

✅ Is This the DDD Dream? – With fewer moving parts (like event storming), does a domain expert in the Mob make DDD even more effective?

✅ The Power of Different Perspectives – Why having a built-in devil’s advocate can enhance team decision-making.

✅ The Truth About Cryptic Code – Can a domain expert help clarify unclear code in real time?
