I am making a use case diagram that includes multiple users. 2 of these users share the same use case but each with different usage.
In case a global use case diagram is already done and a detailed one I needed, how do I detail the difference in the usage of the use case shared by the two users ?
do I make a single diagram and put 2 users with 2 different use case trees from 2 same case ? or do I do 2 separate diagrams for each user ?
Edit : Example if 2 users can manage their account on a platform but one can edit all their profile's attributes and the other can't.
if I already made a use case diagram with both users sharing the same use case
Manage account, how do I details this nuance in the actual usage with an other use case diagram meant to detail the
Manage account use case.
