Task

1.

 

Wagga Base Hospital has a special facility that does X-rays by appointment. When a GP asks a patient to undergo an X-ray and gives him/her a request for an X-ray, the patient visits the Wagga Base Hospital X-ray facility to make an appointment and receives an appointment slip. When the patient goes to the X-ray facility, he/she presents the appointment slip and gets X-rayed; a report is prepared (one copy of which is sent to the patient GP). Identify a use case from this short case study and write a Fully Developed Use Case description.

Rationale

This assignment is intended to enable you to start making the link between theory and practice. The tasks will also help you apply your understanding and knowledge to real-life business situations. Of particular importance is the intention of this assignment to improve your understanding of use cases which are initial medium for describing (in some detail) what a system is supposed to do. The assignment tasks also test your ability to apply your knowledge of, and skills at, producing requirements models such as class diagrams and DFDs.
