I wish to know why I have empties all the use cases brief descriptions. I don't know if this is an assigment error or this is a normal situation.
I've received an assignment called Retire Early Online Trading. It's got me crazy because there are some ambiguous words like ACCOUNT which sometimes I think that refers to User Account and sometimes looks like refers to Bank Account (Number). Also exists the word ADDRESS which could be a physical address or email address.
If I have a full brief descriptions I'm sure that this would be more clear.
Can I be free to assume (guessing) anything about an Use Case?
Can I modify the use case steps order when I draw my sequence diagrams?
Can I skip some use case step when I draw my sequence diagrams assuming by example that certain step could be done transversally (like auth)?
