I came across a situation where a use case has two options to choose from.
Example: Use case “Process data” has options like “Approve” and “Decline”
If approve, update the inventory.
If decline, file the information.
I know how to represent this in an Activity Diagram but I have no idea of showing it in Use case diagrams.
