Q1.
you have learned that Unified Modelling Language (UML) is a standard modelling language, which is diagrammatic, but also allowing developers to add text, and is easy to use, efficiently expressive, unambiguous, widely used and supported by tools. It is a specification language that is used in the software engineering field. It can be defined as a general purpose language that uses a graphical designation which can create an abstract model.
1. In no more than 500 words and using your own words, explain the importance of UML diagrams in software development, especially in large projects such as enterprise solutions.
2. Add relevant diagrams where necessary to explain your answer.
3. At least 3 references. All references must be in the Harvard style of referencing and must be accompanied by proper in-text citations.
Note: Your answer must be formed as a report (Introduction, main discussion, conclusion and references)
Q2.
An agile project has documentation in the form of user stories and tests. A user story describes some functionality required by a user, while a test is an executable form of a user story and therefore directly related to it. Testing early is at the heart of agile development, which promotes, for example, that acceptance tests should be written for each user story before any code is written.
• Assume the scenario of a university’s Student Information System: A university student can register courses online and pay online using the system.
• Suggest at least FIVE user stories as part of acceptance test for the above scenario. You must justify your answer with a brief description.
Q3.
This question makes use of an imaginary software application, the below introduced scenario about a real-time Hospital Management System. You are required to answer Questions from 3.1 to 3.14 based on the scenario.
First Care Medical: A Real-Time Hospital Management System
Introduction
The increase in the patients during Covid-19 outbreaks causes emergency and confused situations in First Care Medical hospital premises. It is crucial for the hospital administrative to ensure proper treatment of sick people while accepting the large volumes of visits. The First Care Medical hospital management believes that due to the current exceptional situation, the existing systems will not help in satisfying the needs of patients. Hence, the hospital management has decided to build a new real-time software system to handle the operations efficiently.
Assumptions
• Currently the hospital is operating using individual systems for various operations.
• You are working in a software developing firm a system analyst.
• Your company has received the order to develop the hospital’s new real-time system.
Further Requirements to complete the development of the system are provided below:
The First Care Medical hospital management requires that the new system should be operational within three months which includes deployment and user trainings. The management would like to ensure the security of the stakeholders. Therefore, the management requested you as the system analyst to ensure the authentication of all users. All registered users must login to the system to perform their assigned tasks according to their privileges. The system should be allow many payment options available as possible, like acceptance of several credit and debit cards, mobile payment apps, and support of multiple currencies. The system will be accessible and usable from all types of browsers.
The system could provide real-time information about vacate beds, available doctors, and staff and can help administrative staff in allotting the required necessities to patients. The system must have facility management features to prevent any equipment downtime. The system should have the feature to monitor the inventory, surgical equipment, other equipment and all essential medications and automatically send alerts for a purchase order. This will ensure the uninterrupted supply of items.
The doctors can keep a patient’s records in easily access databases. With one click, all reports should be displayed on the screen in order to save time. The reports include previous medical history and medications. The doctors should write prescriptions and send to pharmacy, admit to wards if necessary, send request to laboratory and radiology departments and send summary to administration.
With large number of patients in the hospital, it is difficult for the nurses to ensure medicines are administered timely. The system should send patient-wise alerts for medicine and normal check-up time to the concerned nurses. The nurses should be able to view patients’ details, prescription details and ward details. The nurses should be able to view and print their ward duty schedule. The pharmacy staff should be able to view the prescriptions, medicine stock and print receipts. The laboratory staff and radiology staff should be able to view the doctor’s requirements and produce soft and hard copy reports.
The administrative staff should get real-time reports on discharge timings of already treated patients helps to determine waiting time for other patients in queue. The system should help the administrator to decide if it would be practical for them to close the waiting list so that patients can quickly informed and they can initiate a search for another hospital. The system should provide Appointment Reminders, Appointment scheduling and Patient Queue Management. The system should have an appointment scheduler feature for the patients looking for diagnosis to pre-book appointments. Patients will be able to pay online by providing accurate details otherwise the system alerts and rejects the payment.
Members of special taskforce should be able to use a ’Telemedicine’ feature because of the mass quarantine scenarios as well as the insufficient space to accommodate more patients. The system should allow them to implement ’tele-health’ feature. This will ensure only the most needed patients and emergency cases will be admitted and comparatively less sick can be treated virtually at their home. They should be able to assign medical practitioners Video Conferencing feature. The management expecting the proposed system to handle up to 3000 users at a time with a user friendly interface. The system should be designed in a way that a user should be able to learn to use the functionality with maximum one weeks’ training.
The system should allow the Hospital Director to evaluate the firm’s operating results, perform financial analysis, approve the tele-medicine system, appointing doctors for virtual treatment and setting the compensation for patients, if needed.
