| Question 1 10 Marks This question analyses the students’ knowledge in “Automation in Software Testing”. This question will guide the students to know the importance of literature research, referencing and citation which help them to proceed with their graduation project. The answers must be strictly written using own words. |
| “Software Testing is defined as an activity to check whether the actual outcomes match the expected outcomes as well as to ensure that the software system is error free. The testing can be either done manually or using automated tools. Artificial Intelligence (AI) is not only applied to assisting software testers but also across all the roles associated with software development phases in producing top-quality software solutions” Based on the above software engineering concept, you are required to answer the following questions after conducting proper literature research. Artificial Intelligence (AI) can be used in software testing to optimize testing. Discuss on this point with justification using your own words. (Maximum- 200 words) List and briefly describe any five AI-Based Software Testing Tools. Briefly describe any three Benefits and any three challenges of using AI in Software Testing. |

Proper citation of external sources must be included in order to receive mark for this question. |
| Question 2 10 Marks This question analyses the students’ knowledge in “Requirements Engineering” and included as an implementation of practical aspects of software engineering. The concept of Requirements Engineering is covered in Block-1 of the module. |
| You are required to answer the questions by assuming that you have been assigned to identify the requirements of a web based system to manage IT Club at your branch. 1. Identify any three business processes in this domain 2. Identify any three requirements of the proposed system. You are required to classify the requirements into functional and non-functional along with its types. When eliciting functional requirements, attention must be paid to their relative importance. It is important to identify those requirements that are essential only. One approach to prioritization, which is used in the Dynamic Systems Development Method (DSDM) framework is the MoSCoW scheme. You should identify only the “MUST” requirements for the proposed system. a. At least 5 functional requirements are required b. At least 5 non-functional requirements are required 3. Identify the minimum software and hardware requirements. |

| AOU uses many ways to interact with students using various digital channels. AOU believes that it is essential to capture the full digital and physical journey. It will help to gain insights into effective communication which will support potential students and they choose AOU for their study. In addition, AOU believes that working together across the campus will develop relationships with businesses, research opportunities as well as the alumni. To implement this idea AOU would like to develop a Customer Relationship Management (CRM) system. This system is expected to capture and manage the required data and information. AOU wishes that the system expected to be functioning within one semester and a should be platform independent. Both static and mobile devices can be used to access required information. As part of the first phase which is focusing on student recruitment, the system is expected to be used by the registration department, marketing department and faculty advisors. The system should be managed by the system administrator and viewed by the public users as well. After the system analysis stage, it has been suggested that the proposed system should be expected to handle upto100 users concurrently. To support the wide variety of users, the system interface should be designed both in English and Arabic. Following are minimum requirements for the proposed CRM system: The Registration Staff, Marketing Staff and Faculty Advisors will be able to use the system as registered members, the registration is done by the system administrator. To ensure security, verification of the username and password should be done and for any incorrect/invalid entries, the access should be denied. All users will have the privilege to manage their profiles. The Registration Staff will be able to view, update, add and print the details of the students. They will be able to use the SMS feature to communicate with the students. The Faculty Advisors should be able to view the GPA, add and delete courses and print transcript for students. The Marketing personnel will be able to use the system to update the database, print customized details, and send emails. For wrong data entry of email address, |

| the email must be bounced back. The system administrator will have the full privilege the system that includes add, edit and delete users. Based on the above given scenario you are required to present the following using Volere Template (Questions 1-9) 1. Problem Domain 2. Suggested Solution 3. Project Objectives 4. Stakeholders 5. Business Processes (At least TWO) 6. Mandated constraints (At least TWO) 7. Functional requirements: identify THREE functional requirements along with their types 8. Non-functional requirements: identify THREE non-functional requirements along with their types 9. Project issues: choose any one of the project issues 18–26 listed on page 118 of Unit 2 (Section 6.1) and invent an example that could apply to your proposed system. 10. Draw a use case diagram for the scenario |

| Below given paragraph is an extract from the AOU CRM System scenario described in Question-3: The system should store the details of registration, student, courses, classes, faculty advisors, and marketing staff and marketing details. The marketing details to be stored are potential students and companies to be contacted. The student details include student ID, name, and date of registration, date of birth, type of registration, contact number, address and email address. The students’ registration can be full time or part time. The course details are course ID, description and credit hours. The courses are either elective, major or university requirement. The class details to be stored are room number, start time, end time and number of students. Every class room is assigned with a particular course and each course is scheduled in one room. Faculty advisor details are Staff ID, name, College name and job title. Every student is assigned with a Faculty member as an adviser and one faculty advisor advises many students. The marketing details should be stored with a unique ID, type, description, contact number and email address. The |
