I agree with Jan. There should be a package of use cases called Manage System. It is possible to break down use cases by using <<include>>d use cases. Sometimes this is useful but it _is_ effectively functional decomposition and should never be over-indulged. If the end result is intended to be an OO designed system functional decomposition should be used sparingly. It would, IMHO, _not_ be appropriate in this case to have a use case called Manage System which then <<include>>d all use cases for managing the system. -----Original Message----- From: Jan Frederik Solem [mailto:[EMAIL PROTECTED]] Sent: 10 October 2001 19:05 To: ROSE_FORUM Subject: RE: (ROSE) High level use case model > 1.

Well, yes and no. Functional decomposition is exactly what you want to _avoid_ when modeling with use cases; you can't create "high level use cases". But on the other hand you are allowed to group use cases, actors and use case diagrams into several _packages_ - and thus accomplish what you seem to want. > 2.

Well, it isn't the correct way - so...:-) > 3. If this is wrong how do I draw a use case diagram say with 40 or 50 > use cases? You can have a large number of actors and use cases in your model without necessary having to put them all in one big diagram, although some SoDA templates. A use case diagram is not the same thing as a use case model, and you don't necessarily need a use case diagram giving a global view of all use cases and actors in the system. A use case model is the collection of all your use cases, actors, associations between use cases and actors, and all use case diagrams created, to model the functionality of your system.
