1. Posting at least one structured question: provide a paragraph with the context introducing the concept(s), followed by a question that either be interesting, controversial, or both (make your question attractive for others to reply to your question and initiate a conversation) ——————————————————————————————————————
Module 3, assumes that in the planning phase we were able to define a basic scope of a project that supports the strategic objectives of the organization and now we are researching requirements through techniques such as interviews, surveys. or join application development. The requirements identified need to be summarized and shared with stakeholders to ensure that we understand the requirements.
Thus, chapter 6 introduces students to several methods that systems analysts use to determine requirements for a proposed system. This chapter categorizes the requirements gathering techniques as traditional, modern, or radical. The traditional requirements gathering techniques are interviews, questionnaires, Nominal Group Technique, and documents analysis. The modern requirements determination techniques include Joint Application Design (JAD), group support systems, prototyping, and CASE tools. Business Process Reengineering (BPR) is a radical method for determining system requirements.
Next, chapter 7 covers several modeling techniques for representing business processes, and specifically, data flow diagramming (DFD) techniques are introduced. Basic DFD symbols, definitions, and rules are explained (Gane and Sarson symbol set is used in the book). Four different types of DFDs are explained: current physical, current logical, new logical and new physical. Finally, an overview of the process modeling for an Internet-based electronic commerce application is presented.
Based on the previously discussed context, you will post at least one question and respond or comment to at least one question or comment posted by other participants in the discussion board. Your question(s) or comment(s) should go beyond the conceptual domain but also describe or explore how this knowledge can be applied to your current or future professional activities or endeavors.
I expect your posts to be original in all aspects. Consequently, you should not use questions from your textbook for your posting. Further, use secondary references that provide additional information or support a better understanding of chapters covered in the module.
