Hi people,
Currently, I was assigned to a project whereby we require the users to write textual business use cases + use case model.
As for me, who play the role of an analyst and designer, is supposed to 'transform' those artifacts into system use cases and possibly some scenario diagrams.
My big boss keep saying RUP would be used, but I doubt he knows what is he getting into. However, my company has CMM level 4, so I guess, process is not something new.
Question: What are the diffs between business and system use cases? Where can I get info & strategy on 'mapping' business and system use cases?

Hi,
For the difference, you can go here--->http://cafe.rational.com/HyperNews/get/hn/umlcafe/912/1.html?nogifs

I would suggest you to refer "Applying UML and Patterns: An Introduction to OOAD and Unified Process" by Craig Larman, 2nd Edition.This is great book which will clear your doubts, as it did mine.

HTH,
Piyush

Thanks.
One comment, though: In my opinion, the business use case should be high level use case models and each 'bubble' in the use case model should have a textual descriptions about it.
I think System Use Case is a just a realisation of the Business Use Case into system details....either in refined Use Case model or more system like use case writings.
