- State Chart - or state diagram for modeling complex state

Sequence Diagram
- UML diagram
- Consists of participants, typically object or sections of code
- Shows what happens during the lifetime of the participant
- Expresses a particular scenario, with multiple scenarios possible
- Allows explicit modeling of behavior
- Allows expression of flow of control

- Could use software diagram drawing tools
- Could write on paper
