   - model all contracts in terms of what is transmitted among participants
   - model how each software service behaves
6. define a viewpoint and a corresponding view that shows how a key design concern of your choice has been addresses by your design solution
   - environmental goal
   - green strategy + mapping design space + corresponding services
7. Complete design solution with an overview of how each design decision has been addressed
