Why do teams ignore standards they helped write? Wouter Lagerweij on architecture standards adoption and why ownership, not consensus, makes change stick.

Quality as an emergent property of teams, tools and processes rather than something tested in at the end — and how systems thinking keeps it sustainable.

Getting data out of an application is a first-class design problem. Learn how one team replaced 200 hand-copied scripts with templates, and what it cost.

Why does deploying more often improve quality? Why does slack time make a team more reliable? On the counter-intuitive ideas that keep turning out to be right.

Julie Lerman, Indu Alagarsamy, Michael Plöd and Nick Tune on the cost of many ubiquitous languages: everything that gets lost translating between them.

Workshop preparation is where facilitation is won or lost. Katie Clark on consent-based invites, co-facilitation tandems, and using the IKEA effect.

Context mapping used in unconventional ways: multiple business lines, a fragmented technology stack, and what the format reveals under strain.

DDD names the tactical patterns but not the path to them, and domain experts cannot read code. Learn a sticky-note technique for hearing types in domain…

Where AI is used on this site and where it is not: the recordings, the writing, the images, and the site itself.

Larisa Feldman spent years watching architects lose their spark—then became a reluctant architect herself. On why good architecture serves engineers.

At DDD Europe, nine practitioners agreed the problem isn't technical. Discover why facilitation, power structures, and the right people decide outcomes.

Why EventStorming and collaborative modeling fail against cultural resistance — and why a real mandate matters more than the right method.

Laïla Bougria shares how to turn clashing opinions into productive architecture decisions — from reframing problems before solutions to personal retrospectives that build evidence, not arguments.

When developing your software products, be it coding, testing, user experience, product management, or all the other elements required to solve a customer need, do you understand what the rest of the…

What happens when architects draw the same system and get different diagrams? Learn how externalising mental models transforms architecture discussions and reveals hidden disagreements.

The recent COVID-19 pandemic forced us DDD practitioners to move our collaborative modelling efforts to the remote world. Within collaborative modelling, we want to share all the information we have,…
