10. What do use case “exceptions” represent?
We have defined use case exceptions as ways use cases fail to deliver their perceivable benefit of value. There are several kinds of exceptions.
1) System initiated: e g., a required component is unavailable somewhere in the system of systems being used that is not recoverable within this execution of the use case
2) User initiated: e.g., the user cancels out of the use case 3) Benefit not delivered
Note that in the Building Requirements Consensus™ Methodology an exception is defined as a failure to deliver the benefit of the use case. It is not defined by the mechanism that prevents the benefit from being delivered. Some people get confused on this point. They think that because the user cancels the execution of the use case that this is not a use case exception. “After all,” they say, “it is a user action!” However, once the execution of a use case has started, the question is “Was the benefit delivered?” If the answer is “No”, there are only two possibilities.
