Here are some tips for DDD newbies.  It’s easy to fall back to doing ‘what you know best’, so use these tips to stay focused. Hopefully your design skills will get better (and faster) as a result.

1. Don’t start with the User Interface
   Instead of asking “How will the user solve this problem?“, ask “What is the problem?“
2. Design Domain Models, not database schemas
   Most business users don’t understand database schemas – so don’t make them
3. Design your Domain Model incrementally
   Defining too much detail early on is the fastest way to get side-tracked
4. Get constant feedback from your Domain Experts
   Take advantage of TrueView’s auto-generated prototypes to get instant feedback
5. Separate business concerns from technical concerns
   Writing technical infrastructure code can be counter-productive during the modelling phase
6. Unit testing wisely
   Focus on testing non-trivial behaviour and complex business logic, possibly using BDD
7. Think agile, be agile
   Your clients don’t have time to wait, so don’t make them
