Meetup Structure
Why do you want to introduce DDD?
- Consistent language between devs & business
- Architecture that helps
- Allow us to engage domain experts so we can decouple our software
- Maintainable designs
- Avoid DRY on superficial similarity, e.g. Eric Evans Toilet/Sink story
- Add a public API and build a vocabulary for it
- Figure out if we need to build software at all
How to introduce DDD?
- Event Storming
- Start separating domain concepts from infrastructure
- Start writing ValueObjects
- Micro-services are not an end goal, they're a technique along the way
- Identify contexts features affect, use to calculate cost
- Make the costs (and benefits) of DDD known upfront
- Wait for pain, use DDD to solve it
Demonstrate the value
Who do you need to Convince?
Take 2 minutes and write down:
- Who do you need to convince?

- Who do they need to convince?
(Who are the stakeholders?)
Each person will list these out to the room*
