Question

Start with event traces for the simple classes

graph TD
  %% Styling nodes
  style car fill:#f9f,stroke:#333,stroke-width:2px

  %% Subgraph for car
  subgraph car
    a1[Car Status]
    a2[Get Me]
  end

  %% Defining relations
  a1 --|getStatus| a1
  a1 --|getMe| a2

Question

Describe behavioural patterns from the event traces

Question

Continue with the more complex classes

Question

If the behavioural pattern becomes too complicated, consider using the stepwise role or stepwise relation pattern – this introduces new classes

Question

Make sure there are behavioural patterns that control sequence and some that don’t (structured/unstructured)

Question

Add attributes to classes and events

Question

Check the behavioural patterns against the class diagram
