Question

the case study is about the analysis of the students’ understanding in analyzing a given scenario and practical skills to apply concepts and build diagrams studied in IT242 (Software Engineering). The case study consists of five parts. Students are required to answer all these parts based on the below scenario.

The SEU has adopted a blending approach to electronic learning, requiring learners to attend class lectures (25%), while 75% of course time is assigned to virtual classes, learning forums and follow-up of digital learning content.

"SEU Examinations System(SES),"automation of the examination activities of SEU that aims to bring in a centralized system that will ensure the operations in the context of an examination that can manage effectively. This system allows students to register the courses every semester themselves into the system by providing the details or by sharing details to admin at each branch. If the student is doing it by their own, then the system should check the login credentials and then the user can view all his registered courses for that semester along with the other arrear courses from previous semesters. The same is done by providing their student details and all the necessary information like Name, email, registered courses, semester, and so forth. The submitted details are then entered by admin into the SES system to enable the student to attend the examination and also creates a login id and password for them. After creating the login, the system mails the link of soft copy to every student who has registered successfully. Students containing the link in their mail can log in, and view the details of the courses and with the same login credentials they can log in into the system to modify or update their information like phone number, email-id, and so forth. Admin is also responsible for both publishings the grades and the generation of Grade sheets for every registered student after the exams completion. The course instructors are allowed to enter the marks into the system for the courses they teach in respective semesters. Once the teacher fixes the grades, then they have to approve it for admin verification. There will be a total of three to six semesters where each semester contains a maximum of seven subjects. Admin will verify the marks and grades of every student using the system’s GUI or via Database entry and then finally the student grades will be published into their login separately. Students can also request for revaluation of their exam papers through this system. On receiving the revaluation request, the system sends the notification to the concerned instructor and the final grades will be displayed to the students. The system will support 250 concurrent users and can easily integrate with the learning management system (Blackboard) that the university is planning to purchase. Thus, on the whole, it serves as a completely automated software which handles every tedious and complicated process handled

during the examination times by covering for the most significant drawbacks of a manual system, namely speed, precision, and simplicity. A centralized system will ensure that the activities in the context of an examination can be managed effectively, while also making it more accessible and convenient for both students and staff.

Deliverables

The parts of this case study yield many outputs. These outputs will be the means of evaluation of each part of the case study. On or before the due date, the group leader (selected by the students’ group) must upload only one Word-format document to the Blackboard.

Based on the given scenario, answer the following parts.

Questions of this part analyze the students’ understanding in analyzing the given scenario to identify functional requirements (FRs), non-functional requirements (NFRs), and practical skills to build use case diagrams studied in chapters 8, and 9 of IT242.

1. List two functional requirements (FRs). (2 Marks)
2. List two non-functional requirements (NFRs). (2 Marks)
3. List the actors of the proposed Website. (2 Marks)
4. Draw a use case diagram for the given scenario. (5 Marks)

Answer 1
