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?
  (What is their role?)
   
• Who do they need to convince?
  (Who are the stakeholders?)

Each person will list these out to the room*

The Pitch

How do you sell the idea?

To introduce DDD you need to understand:

• What it is your selling
• Who you're selling it to
  • What are their goals/motivations
  • How does DDD help them reach their goals
• Why they could be resistant to change

Why, Who, What & How

Break into groups of two and spend 10minutes on:
 

• Why do you want to introduce ddd?
• Who do you need to convince?
• What are their goals and motivations?
• How do you align the why, who & what?
  (How do you sell the why to them)

Each person will list these out to the room*
