Activity 6.4: Modeling Dynamic
Behavior
Dynamic models provide the development team with a detailed picture of the
relationships of use cases and usage scenarios. The models provide current state
descriptions of the workflow processes and important task sequences.
In this activity, you will develop activity, interaction, and state models for the
Ferguson and Bardell, Inc. case study.
