I am making the specification of these use cases and I have these cases of abstract uses, the question is the following, I need to detail the cases of abstract uses, or only the specialized (or generalized) cases, ie in case of listing users, should I specify the use cases list attendants and list supervisors, or just specify the use case list users and put conditions to list attendants or supervisors as alternate flows?
If none of these statements is correct, what would be the easiest way to represent these actions in the diagram, rightly and easy to specify later?
