Question No. 1 [Marks 15] Consider a library management system of Virtual University of Pakistan which maintains a list of books for students, teaching assistants and faculty members to borrow. Each user has its own username and password. Note that it should be fourteen characters long at least. Users should not be allowed to use the system without providing a valid username and password. Whenever a user login into the system, he is provided with an interface to search the required book. After searching the book, he/she selects it for borrow. After entering details, the book is released for the user for fourteen days. After fourteen days either he/she will have to return the book or apply for re-issue. The book should be issued second time as per round robin policy i.e. if no other student/faculty is waiting, the book will be re-issued else it will be available for next student waiting for the book. You can use circular link list for this purpose. Faculty members can also borrow the books according to same rules mentioned above. He/she also follows the same process i.e. he/she selects the book, enters information and clicks submit button. Finally, the book is issued for entire semester. After semester, either he/she should return the book or apply for re-issue. For re-issue, same round robin policy will be applied. As system is used by many users at all levels (including new comer students), it should have high usability and there should be no performance issues. Keeping in view the quality attributes of Software requirement document, identify the quality issues with the requirements given above. For convenience, one example is given below in tabular form below. Identify and mention five other issues. Quality Issue Reason Incomplete Requirements say that: “Consider a library management system of virtual university of Pakistan which maintains a list of books for students, teaching assistants and faculty members to borrow” Faculty member can borrow book for entire semester, but no information for Teaching Assistants. i.e. for how much period they can borrow the book. Question No. 2 [Marks 15] From the above scenario (given in Question No. 1), give at least one example of: • Functional requirements • Non-functional requirements • Domain requirements • Inverse requirements • Design and Implementation constraints Question No. 3 [Marks 20] Read the paper titled “Software Quality Assessment in Practice: A Hypothesis-driven Framework” attached with this assignment and answer the following questions: Provide a brief summary of the paper (less than or equal to 250 words) Provide critical review (i.e. strengths and weaknesses of the paper)

Video Presentation of Academic Research Paper For the presentation activity, students are required to record their video while presenting academic research paper slides, then put recorded video and slides in a zip file and upload it on VU-LMS. Therefore, each student is required to prepare PPTs of his/her academic research paper and then record his/her video while presenting the slides. Following are the guidelines in this regard: PPT Slides: Prepare presentation slides related to your academic research paper. There must not be more than 20 slides in your PPT file. First slide should contain student-ID, student-name, topic and course-name. Your presentation should describe the problem statement, methodology and conclusion. Save your presentation slides in .ppt or .pptx format. Video Recording: You have to formally present the slides with proper dress code and have to record the video of your presentation. You can use any video recording facility such as web cam, camera, mobile phone etc. for recording of your presentation (Download link of the tutorial “Tips for Recording Videos” is provided in the assignment package). The total time for recording should not exceed 10 minutes. After recording your video, you have to convert it in “.3gp” format using any video conversion tool to reduce the size of the video file. (Download link of the tutorial “Video Compression” is provided in the assignment package). After converting the video in .3gp format, review your file to verify that audio and video are playing properly. Install VLC media player to view your compressed video before uploading on VU-LMS. You can download VLC from http://www.videolan.org/vlc/download-windows.html. It is preferable to use English in your presentation in case of reluctance you can also use Urdu language. Note that you will record your presentation standing in front of camera. Students writing academic paper in group should submit presentation individually with their own video recording. Submission: Compress your video file and presentation file using any compression tool like WinZip or WinRAR. Upload the compressed file (.zip or .rar) on VU-LMS. Make sure that its size should not exceed 30 MB. Note: It is not required to show PPT slides in the recorded video.
