Scenario Walk-Through

I l @ ve RuBoard

A primary method of consistency checking is to walk through the high-risk scenarios as represented by a sequence or collaboration diagram. Since each message represents behavior of the receiving class, verify that each message is captured as an operation on the class diagram. Verify that two interacting objects have a pathway for communication via either an association or an aggregation. Especially check for reflexive relationships that may be needed since these relationships are easy to miss during analysis. Reflexive relationships are needed when multiple objects of the same class interact during a scenario.

For each class represented on the class diagram, make sure the class participates in at least one scenario. For each operation listed for a class, verify that either the operation is used in at least one scenario or it is needed for completeness. Finally, verify that each object included in a sequence or collaboration diagram belongs to a class on the class diagram.
