CASE STUDY

During requirements modelling for the new system, you met with the office staff and the partners. Things were moving very quickly, and positively. Assume you conducted a series of interviews, reviewed processes, observed business operations, analysed the payment processes, and studied a sample of the reports. The objective was to develop a list of system requirements for the proposed system. You found the following information about the system inputs and outputs.

OUTPUT DESIGN
The recommendation for a new computer system has been approved by the practice's associates. A key step in the development of the system design is specification of the system's outputs. The following outputs need to be designed.

INPUT DESIGN
Now that the outputs have been determined it is time to consider the inputs to the system and the design of the interfaces to capture the information needed.

DATABASE DESIGN
After completing the input and output design you now have to give consideration to the design of the database. The information shown on the inputs and outputs must be able to be entered and stored in a database for retrieval.

SYSTEM ARCHITECTURE
Assuming the input and output specifications and database design has been accepted by the associates, you will now need to examine the hardware requirements for the system. The office system will require a server and 4 workstations in the office and a further 8 workstations for the doctors and therapists. There will need to be a backup system and processes to ensure the integrity of the systems data. A multi-function laser printer and a colour laser printer are also required.

ACTIVITY
1. Write down a list of the main functions needed to be handled by the new system.
2. What are the roles that will be interacting with the system?
3. Using all the information that you know about the Clinic's business operations so far, create a use-case diagram for the new system.
4. Select four use-cases and write a brief use-case description for them.
5. Pick one of these use-cases and write a full use-case description for it. Use an activity diagram in the full description.
6. Include the following in your report:
- the use-case diagram;
- the brief use-case descriptions;
- the full use-case description, including your activity diagram.
