Every time I explain strategic #DDDesign, I do it in a slightly different way.
The order in which the concepts are introduced influences a lot. Today I'm trying:
1. Models
2. Domain Models
3. Subdomains and Types
4. BC and UL
5. Context Mapping
I used to skip Models, and briefly DM

New tale talesfrom.dev/blog/the-amb... in which we observe people discussing names - what are the consequences? Does naming create something which is invisible? Why naming can be dangerous?

Claude Code has been on fire this week.
I hooked it up to all the domain events produced by our system and it's been helping me figure out issues much faster than I could alone.
Domain-driven design is a differentiator.

One of my software design nemeses is reliance on the UI to enforce business rules.
I don't mean hard-coding business logic in the UI, I mean assuming that certain operations or state transitions aren't possible because a user must go through the steps in the UI in a certain order.

Last week, I received a box full of the new printed book "Architecture for Flow" by @suksr.bsky.social
It's available on InformIT(.com) now and from Amazon with 1-2 day delay, which is likely because it's selling like hotcakes:
#8 in Software Design & Engineering

Forget the preconceived idea that more bounded contexts creates overhead. Be pragmatic in the design and in the implementation. Don't be dogmatic about the rules. The core of #DDDesign is to have the right tools for the right problems.
Stop addressing the symptoms. Split those models.

If I had to sum up
#DDDesign in one sentence, I would say:
"Domain Driven Design is about seeking efficiency when creating software (aligning our solution space with the problem space)"

Moin Hamburg! On the 21st of November there will be a local DDD meetup on Domain-Driven Transformation with @hschwentner.bsky.social. He will present a catalog of refactorings that help cure: BBOM architecture, anemic domain models, and badly organized teams.

Happy to restart #DDDHamburg with “Introduction to DDD—It’s All About the Domain, Honey” on Dec 6!
We look on the foundations of Domain-Driven Design, but it’s also a gathering of the community. Plus: pizza and Glühwein 🍕🎅🏼🍷
