Find scenarios in the business use cases that will be refined into descriptions of how the business
accomplishes those scenarios. Generally, high-priority or critical scenarios are the first that are selected for
refinement into business use-case realizations.
It can also be useful to create UML activity diagrams of the candidate scenarios to determine their criticality
and provide input to later steps in the task.
Create a sequence diagram for each selected scenario, and place it in a business use-case realization that realizes the business use case. Create the
realization if one doesn't exist, and add a realization relationship from the realization to the use case on a Business
Use-case Realization diagram.
See Describe the Business for details on creating and adding sequence diagrams to
the business use-case realization.
