I’m working on a business question and need support to help me study.

I have 2 Business IT case study assignments, i’m posting one now to understand the work and then I will send the other one and its with less case studies. I will post the questions and upload the case studies and the materials, let me know if anything is unclear or if you have any questions.

Answer the questions below in the context of each of the following five cases (all pdf files) of real-world business information systems.

QUESTIONS

1. The information systems described in these articles don’t really fall neatly into a single IS category such as TPS, MIS, DSS, ESS, ERP, SCM, CRM, KMS, collaboration environments, GIS, GDSS, etc. Rather, most seem to possess functionalities from more than one category. Identify and discuss the multiplicity of these categories for each system.
   (As a hypothetical example, one particular article may describe a system that primarily appears to be a DSS for mid-to-upper-level managers working in finance and accounting, with other functionalities that resemble an MIS designed for lower-to-mid-level managers in sales and marketing. Your answer will need more elaboration and discussion, of course.)
2. Each system assists its respective users with decision-making in their work environments. In what stage(s) of their decision-making (Figure 12-2 in the textbook) does it provide them with assistance — intelligence stage, design stage, choice stage, and/or implementation stage? Discuss and justify your answer.
   (Address how each completed, implemented system is proving useful, not the process by which it was conceived and acquired/built.)
3. Each system is probably interconnected/linked to other information systems in its organization. Although the articles themselves do not address this aspect, from your understanding of organizations, business processes, and systems, describe some possible/likely examples of such interconnections for each system. Explain your reasoning, while explicitly stating any assumptions.
