Discuss about the case given below/Management Information Sys
Requirements Specification
Before you begin this assignment, be sure you have read the Case Study and all assignments for this class, especially Stage 4: Final System Report. The feedback you received on your Stage 1 assignment should be reviewed and used as you proceed with Stage 2.
Purpose of this Assignment
This assignment gives you the opportunity to specify clear and concise requirements, including the use of data and process models, for a system that enables a productive change in a way the business is conducted. This assignment specifically addresses the following course outcomes to enable you to:
• apply a systematic approach to translate requirements into an executable systems design
• effectively communicate with stakeholders to determine, manage, and document business requirements throughout the SDLC
• perform modeling to assist with analysis and decision making
Assignment
The results of your systems analysis and design work in this class will be documented in a Final System Report. The purpose of the Report is to inform management of your system proposal and gain approval to proceed with the project. The Report will be developed and submitted in stages, which will be compiled at the end of class into the Final System Report. Review the outline of the Final System Report in the Stage 4 Assignment description. Note that it contains the analysis of the problem(s) and requirements, and proposes what kind of a system solution is needed. It does not propose a specific solution, but it does recommend why and how the organization should acquire the solution.
Following the Preliminary Investigation Report (Stage 1 assignment), the next stepis to identify the requirements for a system, documenting them in the Requirements Specification document. The purpose of the Requirements Specification is to clearly define what the proposed system will do in non-technical user-oriented language. It should identify what data is entered into the system, what output is required, what processes the system should perform, what protections and controls are needed, what performance is expected, and what the business continuity needs are. In order to clearly express the requirements, data and process models are used to communicate how the system should work.
All of the information you need to complete the projects in this class is not provided in the case study. In the discussion area of the classroom, there is a discussion titled “Case Study Interview Questions” where you can pose questions about the case study, as if you were interviewing the people in the case study organization. Any information that you need that is not included in the case study should be asked about in this discussion. Responses from the faculty member on behalf of the case study organization will be available for everyone in the class.
Use the information provided in the case study and the Case Study Interview Questions discussion to create a checklist of functional and technical requirements and the data and process models listed below. Using the formatand resourcesbelow, list three requirements for each of the areas shown in I and II. Then, create two diagrams to illustrate the scope of the system: the context diagram and theuse case diagram. Then, create thedata flow diagramto illustrate the flow of the inputs and outputs listed as functional requirements in section I. You should then select a process or process step (from those listed in section I.b – processing requirements) that has some decision associated with it to create the three process models listed below.
The same process/process step will be used for all three of the process models; they are just different ways to represent the process and the decision involved. Approximate lengths for each section are provided as a guideline; be sure to provide all pertinent information. References in brackets are to the two e-textbooks (by authors Jawahar and Conger) used in this class and the page on which the explanatory information begins.Use the examples listed in the brackets to develop your diagrams.
There are several different methodologies using different symbols, but your diagrams will be graded for compliance with the examples listed. You are required to use the symbols and diagramming methods illustrated in the examples, and follow any rules for the diagram in the sources listed with each diagram.
