Authors Approach Authors Approach Do first cut sequence diagram including only actor and problem domain classes. Add view layer and data access layer classes and redo sequence diagram. (Note: there is little basis for the view layer or how it operates.) Complete the design classes based on top two exercises Problems: Creation of sequence diagrams occurs several times and sequence diagrams are complex and timely to create. Little understanding of how the use case is visualized, so classes added might require revision or deletion. The use of controllers is undefined and rules for what type of object should communicate with another are not defined, causing later revisions in model. Design class attribution is a guess and might require changes later.

Robustness Approach Robustness Approach Build User Interface prototype explaining the visual solution to the use case. Perform robustness to discover new controller classes and add UI classes from prototype. Confirm through robustness, applying rules, the flow of control in the use case with all defined objects being added to model. Develop sequence diagram adding methods to defined design classes. Complete the design diagrams with discovered attributes. Benefits:
