Computing Assignment Help: Use Cases

Question

Hi there,

Ive got a section in the assignment where it asks:

' Model key aspects of the problem (such as the functional requirements for the proposed system) using use cases. You will need to break the system up into at least 2 levels to get the marks.'

I know what use cases are... I've got my normal actors and use cases and have arrows connecting them together to show relationship. But i'm not sure what it means by saying breaking it up into 2 levels?

Any help will be appreciated! thanks! :)

Answer 1

I had a similar assignment recently... Perhaps breaking your use cases into 2 levels could be a task unique to your particular assignment or project?

Say for example there are two different options in the GUI that each take you to a similar set of use cases... or maybe a step somewhere in the process of your program that brings your user to basically a "fork" in the road that leaves them two different paths to continue on, hence... 2 levels...

That's the only thing I could think of...

I hope you figure it out... I despise when professors are ambiguous, I swear they do it on purpose :).
