...Part 1- Specifications Table (MS Word) Case Study- Director’s Request for PCs Please use the document “Case Study Instructions Director’s Request for PCs” found in the Case Study Instructions conference topic for the list of requirements which should be met by this project. Part 1: For the case study outlines in the Instructions topic, create MS Word tables that identify and contain the hardware and software requirements to meet the director's requirements. The MS Word document in its final form will include 5 MS Word tables. It will include a two-paragraph narrative summary that classifies the user type and identifies the PC category(ies) that will be recommended. Think of the narrative summary as an executive summary where you outline the recommendations without going into a great deal of detail. You will write this executive summary after you have completed the tables. But place the executive summary after your title page, BEFORE the 5 tables. Students are expected to conduct external research to adequately address all aspects of the assignment requirements. Any outside sources should be correctly cited in APA style at the end of the table. Students will need to include specific requirements from the case study to show why each item is being recommended. Each element listed below must be incorporated into the assignment. Omissions will result in loss of points. |Requirement |Points Allocated ......

Software Requirement Analysis and Specification

...Abstract:-Software requirement analysis is a method to find out the requirements form the user to develop software. Software requirement analysis and specification also include the types of user requirements and the methods by which developer team can elicit the user requirement and develop suitable software for the user. Introduction:- ➢ Requirement analysis: - Requirements analysis, also called requirements engineering, is the process of determining user expectations for a new or modified product. These features, called requirements, must be quantifiable, relevant and detailed. In software engineering, such requirements are often called functional specifications. Requirements analysis is an important aspect of project management. Requirements analysis involves frequent communication with system users to determine specific feature expectations, resolution of conflict or ambiguity in requirements as demanded by the various users or groups of users, avoidance of feature creep and documentation of all aspects of the project development process from start to finish. Energy should be directed towards ensuring that the final system or product conforms to client needs rather than attempting to mold user expectations to fit the requirements. Requirements analysis is a team effort that demands a combination of hardware, software and human factors engineering expertise as well as skills in dealing with people. ➢ Software requirement analysis: - The success of any new......
