Characterization by Behavior

Just as an Abstract Data Type is characterized more by behavior than by representation, the goal in using Responsibility Driven Design will be to first characterize the application by behavior.

First capture the behavior of the entire application.
Refine this into behavioral descriptions of subsystems.
Refine behavior descriptions into code.

This emphasis on behavior is a hallmark of Object-Oriented programming.
