Global Recipe

1. Preparation
   • draw a context diagram on a whiteboard
   • draw the common scenarios of your software system
   • preferrably, perform these exercises with your colleagues and stakeholders
2. Repository
   • create all identified components
3. Protocols
   • design all identified protocols: interfaces and state machines
4. Context
   • create a Context Diagram
   • draw component instances
   • draw connections between instances
5. Decomposition
   • decompose component(s) into subcomponents
   • decompose component(s) into classes
   • draw (delegated) connections between components/classes
6. Scenarios
   • draw sequence diagrams of normal behaviour
   • draw sequence diagrams of exceptional behaviour
7. Finite state machines
   • design the finite state machine of classes
