Define Enterprise Scenarios

In this activity, one or more enterprise scenarios are defined for each enterprise use case to specify the interaction between the system and the external systems to achieve the use case goals (i.e., mission objectives). The enterprise scenarios provide the basis for specifying the system behavioral requirements. A complete set of scenarios, which correspond to each primary and alternative path for the use cases, are needed to completely specify the system requirements. This may involve additional refactoring of the use cases to identify common functionality. The modeler should also ensure that the following are addressed:

• High likelihood scenarios

• Performance stressing scenarios and scenarios that significantly impact the moes

• Failure scenarios

• Critical system functionality

• New system functionality

• Interactions that include all external systems and users
