Having a canvas that brings people together is a major accomplishment of #EventModeling. Using it to guide your organization, it's important to distinguish the "What" from the "How".

Event Modeling for the regular systems:
When you have a regular architecture and approach in your development, use #EventModeling to plan your solution and get your cost curve flattened as well.

Designing systems using diagrams that allow branching/looping leaves you open for many oversights under the illusion of the opposite. A temporal view is critical for understanding. The #eventsourcing mindset unlocks that secret - even if events are not used in the implementation.

There are hundreds of benefits for describing your system with adherence to
UI -> Command -> Event -> State View
as the simplest rule to decompose complexity into visible artifacts that you can plan properly against.

As opposed to UML which favours OOP, DDD which favors aggregates, etc. Event modeling gives you the freedom needed to automate with whatever architecture you like to use. Thanks to @enordfjord and the rest of the community for helping so many. Join us in the slack group!

A shared vision for your system can't be really shared if it exists in 10 different documents. It needs to be a single blueprint. Sharing 1 thing is much easier than sharing 10 things.

Divide and conquer with #EventModeling by specializing in one of 4 disciplines: command populators and their potential UIs/APIs, command handlers that isolate state changes, event handlers that build views and page/report constructors that show views.

From the meetup on Friday. How we move past just "compare and swap" for event number in #eventsourcing. This allows arbitrary invariants across streams. This tightens the loop for eventual consistency and stores the invariant function itself as part of the event.

No matter what your technical or business tooling is (patterns, methodologies, etc), information flow is the ultimate test that you have a working system.
If your methodologies don't use real data to show what the system has and how it shows it to the users, you're flying blind.

#EventSourcing is everywhere.
Do you know the addresses you lived at in your life? You don't just forget the old address when you move. Yet we write systems like this.
If an address is in a different country, a projection called 'immigrant' is 'true'
