Subject: Software Quality Engineering Assignment Objective: To know about importance of quality framework To know about Cost vs Quality Software requirements Software completeness Software quality characteristics Software debugging tools Question-1 Suppose you are working as a software quality assurance engineer in a software house name XYZ Pvt ltd. Your company is developing online examination system for the university. This system conduct the online examination of its students distributed throughout the country. The major software requirements are that teachers can create papers, students can attempt the paper and teachers then can then mark the papers and publish results. The system should perform all these activities in reliably and efficiently. You have to have to ensure the quality of the software you are developing. International Standard for Software Evaluation is ISO-9126. This standard provides a framework for quality definition in hierarchical form and these are organized into quality characteristics. According to the above scenario provide implementation of six top-level quality characteristics. How these can be applied in the above scenario. Also justify your answer according to the above scenario. Write your answer in bullet points in each of the quality characteristics related to the above scenario.
