When to Use Interaction Diagrams

When to Use Interaction Diagrams

You should use interaction diagrams when you want to look at the behavior of several objects within a single use case. Interaction diagrams are good at showing collaborations among the objects; they are not so good at precise definition of the behavior.

If you want to look at the behavior of a single object across many use cases, use a state diagram (see Chapter 8). If you want to look at behavior across many use cases or many threads, consider an activity diagram (see Chapter 9).
