Experiment 4.2 (Requirements Specification Document) Objective Identify the elements in software Requirements Specification document. Estimated Time: 40 minutes Background The output of requirement analysis place is the Software Requirements Specification it should specify what a system should do. Atypical SRS usually consists of the system overview (both current and proposed). Objectives of the proposed system such that it is proven to be significant development over the existing system, business analysis of the client functional and non-functional requirement, glossary, etc. Problem Description (6 points) Article Systems (AS), a giant books franchise has approached IT company ABCLtd. To help them automate their business processes and shift them online so all of its outlets across the globe would be under one portal. AMC Ltd., agrees to take on the project and both the companies sit down and strike a deal. After detailed discussion and analysis, ABC Ltd. decides to follows the waterfall model for development of the project. This discussion covered topics such as the business analysis and operations of AS, The expectations of the client (AS) from ABC Ltd, their needs and requirements from the software, their current existing system including its limitations and what the proposed system would do to address these issues. Taking into account all the input, the concerned team at ABC designed and developed the SRS. Which of the following are typically expected to be found in the SRS created by ABC Ltd. Towards the AS Project? Put an X mark in the second column of Table 2 for those SRS elements that will be included in the SRS document then explain why you have selected these elements in table 3. Table 2 Elements in software Requirements Specification document System Overview Class Diagram Source Code Use Cases Flow Charts for algorithms realizing the functionality of the system Code review Comments test results The Difference in the scope of the current system to be proposed system. Non-Functional requirements Features of new portal to be developed Table 3 Type your explanation inside this box. To be included
