- Determining System Requirements MIS One of the potential problems with gathering information requirements by observing potential system users is that people may change their behavior when observed. What could you do to overcome this potential confounding factor in accurately determining information requirements? All of the methods of data collection discussed in this chapter take a lot of time. What are some ways analysts can still collect the information they need for systems analysis but also save time? What methods can you think of that would improve upon both traditional and newer techniques?What is a model in System Analysis? Differentiate between logical and Physical model.Each company should include both a succinct explanation of information system activities and real examples of information system activities. This is an essential need.
- Enterprise system software vendors need business systems analysts who understand both information systems and business processes. Make a list of six or more specific qualifications needed to be a strong business systems analyst who supports the implementation and conversion to an enterprise system within an SME. Are there additional/different qualifications needed for someone who is doing similar work but for a large multinational organization?In information system acquisition, what are the primary challenges associated with maintaining alignment between business goals and technology solutions?As a newcomer in the subject of system analysis, what do you think are the most important considerations to keep in mind while creating an information system to boost a company's efficiency and productivity?

What are the arguments you make in favor of or against this?For each of the following business situations, identify and justify the most suitable Management Information System subtype that could be implemented: (i) A shoes producing company wants to make different decisions regarding the production process whenever these are required. Specifically, they want to be able to effectively answer questions such as “If one of the production process machines breaks down, what is the effect on the company’s ability to satisfy customer demand for our products?” and “If we add an additional shift to our daily work schedule on one of our production process machines, what impact would this have on our throughput per day?”. (ii) A company wants to provide expert help to its technicians when diagnosing and repairing faults in complex electronic control systems, without having to commission and wait for the human expert to attend each time.Q.
