1. Full Use Case Description (40 marks)
Select the most critical core use case identified for the case study* and fully describe it to

produce a full use case description. (use the template provided in Resources section).
Make sure your full use case description identifies and describes all significant alternate flows

Guidance for selecting a use case will be provided during semester. If you wish to start this task before such guidance is provided, check your selection with the lecturer before starting work. Your mark for the whole assignment will be negatively affected if the use case you select is not one of the approved use cases.

1. Activity Diagram (20 marks)
Produce an activity diagram consistent with the full use case description. Make sure your

activity diagram shows the same steps and flows as contained in the full use case description.

1. System Sequence Diagram (20 marks)
Produce a system sequence diagram consistent with the normal flow detailed in the full use case


1. Operation Contract (20 marks)

Identify the most complex user-system interaction (input/response couplet) within the normal flow (ie the step with the most number of side effects, or most complex internal logic), and produce an operation contract for that input-response couplet.

It is impossible to provide guidance as to which step of the use case to select for this task. However, your mark for this section will be negatively affected if the step you select is clearly not the most complex interaction in the use case you describe.
