Define Use Case Boundary (Process Notes 2.2.2)

Determine the use case(s) for business events. For each business event:

• Consider the business opportunities.

• Review the work knowledge.

Decide the boundary between the product and the actor. For each use case (there might be more than one per business event):

• Define the actor names.

• Define the use case name.

• Define the use case boundary data.

• Record the product context by adding the use case to a use case diagram.

• Keep track of which business event name(s) is (are) related to this use case.

If you have more than 15 to 20 use cases, then a use case diagram will be too complex and you will need to draw a leveled use case diagram or create a use case list.
