11.3 Further Analysis
We could now document this proposed design using UML diagram and program a system accordingly. However before doing so it would be better to find any potential faults in our designs as fixing these faults now would be quicker than fixing the faults after time has been spent programming the system. Thus we should now refine our design using CRC cards and elaborate classes.
CRC card (see Chapter 6 section 6.10 and 6.11) allow us to role play various scenarios to check if our design look feasible before refining these design and documenting them using UML class diagrams.
The two CRC cards below have been developed to describe the client and ClientBook classes.
The panel on the left shows the class responsibilities and the panel on the right shows the classes they are expected to collaborate with.
