I am currently modelling a system that I propose to implement

One feature or functionality is for the user to browse for music. But then they could also search for it - so does it mean that the search for use case include from browse music use case?

Thanks

Ah, my favorite ...

No, it does not include it. Search music is a single UC (it delivers a list of music titles). Browse music is no UC in contrast. It's simply an action you take (maybe at the end of Search music). A use case must deliver some added value. Just browsing is not really added value (ok, one can start arguing here - but ...).

  • Wouldn't it be the opposite --- the UC being "Browse music" with the capability of searching, sorting, filtering, ...? Or would those be two (three) different UCs? – Peter Uhnak Jan 24 '16 at 12:15
  • @Peter The idea is to get the single points in the system that deliver added value. Not to model functionality how its connected. – qwerty_so Jan 24 '16 at 14:23
  • Yes, one can start arguing. But whether "browse" is legitimately a use case or not, I don't see any sort of include relationship. Neither searching nor browsing includes the other: when you search you search, when you browse you browse. – BobRodes Jan 29 '16 at 07:17
