I have three questions about use case.

1. Can I add use cases if I think that it is necessary for our design?

2. Can I modify the basic flow of a use case? Such as:
Basic flow:
[1]. do something;
[2]. do other things
[3]. finishing all things.

I think that this basic flow might miss something: I add [0] before [1] and/or [2'] between [2] and [3], etc.

3. If a use case just provides a basic flow, and does not have alternative path, can I add alternative path?


Thanks,

I dont think it is good idea to add use case or modify it. Think about what is like in reality. I understand use case is defined by business and got approved by project steering commitee and budget planning. Any change to the requirements from business is significant and very political. In Cade's book he also mentioned that you might not agree the business domain model, but you cannot change it and must support it. I guess use case apply this rule as well.

You can, but if I'm an evaluation member, I will not add any score for additional works.

Why do you want to add/modify use cases? This is an exam, not the real things.

Well, what my concern is that if login/logout use cases do not provide, I would like to have it. I need to add use cases. Also, if the basic flow of use case does not mention about login which is needed in that basic flow, thus I need to add it. Is it correct? Thanks,
