in the SCEA Part 2, do we have rights to change the use case specification and flow ? I read the description over and over again, still doesn't make sense to me, can I change the use case and specification and flow ? certainly I will make clarification in the assumption.
in the class diagram, what level of details we should provide ? I should define each attribut, methods ? by default, the class diagram Oracle gave to us doesn't include any attributes and methods.
