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), ie, in the case of listing users, i should specify the use cases list attendants and list supervisors, or just specify the use case list users and put the conditions to list attendants or supervisors as alternative flows?
If none of these statements is correct, what would be the easy way to represent these actions in the diagram, in the right way and easy to specify later?
