Case Study: COVID-safeguard System
COVID-19 is a pandemic which is causing social, economic and health issues for the whole world. Many governments around the world are using advanced technologies to prevent COVID-19 outbreaks in their countries. For example, some of these advanced technologies are use of CCTV cameras to monitor people movements, drones to warn people to use face masks and mobile apps to track the social contact among people.
Let’s assume that you are working as a system analyst and your key skills are to design and develop information systems. Australian government has contacted you to develop an information system to collect information to help reduce the spread. The system can be called as COVID-19 safeguard. The main aims of COVID-19 safeguard information system are to identify clusters of infected areas, monitor quarantines, and educate people about social distancing and maintaining hygiene. The overarching goal of this project is to reduce the transmission of COVID-19 among people.
The information system should use advanced technologies such as CCTV cameras, drones, mobile signals such as Bluetooth, mobile phone data (i.e., location, date, time etc.) or any other technology that you think will be helpful in the design of this system.
Deliverables:You will complete the three main tasks including understanding the problem (assessment item 1), requirements gathering (assessment item 2), and requirements report (assessment item 3) as part of this project.

TASK
back to topFurther background
Refer to the Project Vision Document submitted in Assessment Item 1 regarding COVID-safeguard project. In this assignment, you are required to prepare various system analysis activities for the proposed system.
Please refer to the marking guide when preparing your response to see what criteria and standards will be used to assess your work and your progress.
Assessment Item 2 Tasks
This assignment has four (4) tasks as described below:
Task 1. Identify and briefly describe the functional and non-functional requirements for the proposed COVID-safeguard system. (1500 words)
Task 2. List the possible domain classes and their attributes for the proposed COVID-safeguard system and draw a domain model class diagram. Be creative and add those domain classes you think should be included to make the system useful and appealing.
Task 3. Based on the information you obtained for COVID-safeguard system, identify all possible states and exit transitions and then develop a state machine diagram.
Task 4. Write a fully developed use case description using ONLY one use case for the proposed COVID-safeguard system.
RATIONALE
back to topThis assessment task will assess the following learning outcome/s:
- be able to discuss and describe processes to systems analysis.
- be able to compare the range of requirements gathering techniques.
- be able to describe and apply feasibility study methods and approaches.
- be able to develop system requirements models.
