We have a use case diagram for our software engineering course project that we have many use cases in every system and about 5-6 actors. How should we separate this heavy diagram to light weight diagrams? What is standard way to do it?
Should we separating per actor or per system?
By per actor I mean: e.g. for a management system that has two actors we open a diagram with that system and just show actor #1. After that we open other diagram put the same system in it but show just other actor (actor #2).
