Hi,

I have 4 uses cases in my assignment. I will have sequence diagrams for each of them.

But there is also one feature (like inventory check) which is not specified as part of the use case in the assignment, should i include sequence diagram for inventory check too

Please advise

thanks

I created a separate sequence diagram for this which is also reusable and reference this in the main sequence diagram when required.

I did the same thing - a separate sequence diagram for login.

Hi Jeanne,

Should we consider login/logut actions as a part of SuD even if they weren't reflected in any of use cases? Could we just assume that for each use case there is precondition: user has been authenticated and authorized.

You can assume anything you want. It's a judgement call .
