Assignment use cases without Brief Descriptions

Hi,

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)?



  • Thanks.

  • Yes. Just be sure to document your assumptions.

  • Yes. The sequence diagrams can be run in any order.

  • That's fine.

    Thanks Jeanne!

    If you know about it... The absence of use cases brief descriptions occurs as well in other assignments or could it be an assigment error?
