- Please provide short explanations of any two of the following: The potential advantages of information systems for management2. Assume you are a systems analyst for a consulting company and have been asked to assist the chief executive officer (CEO) of a regional bank. The bank recently implemented a plan to reduce the number of staff, including loan officers, as a strategy to maintain profitability. Subsequently, the bank has experienced chronic problems with backlogged loan requests because of the limited number of loan officers who are able to review and approve or disapprove loans. The CEO of the bank is interested in solutions that would allow the approval process to move faster without increasing the number of loan officers, and has engaged your company to come up with sugges-tions. What is one type of system that you might recommend to the bank?Write a memo based on this scenario, use FIPS 199 (FEDERAL INFORMATION PROCESSING STANDARDS PUBLICATION) available online, and research on the functionality of an accounting system, Your company is purchasing a new accounting system. Evaluate the system using FIPS 199 to determine if it is a low, moderate, or high impact system. You need to provide justification for each of the three areas of evaluation for the level you select for that area and a statement of what the final level for the system has been determined to be. The evaluation of each of the three areas must include a list or explanation of what you considered in that area as the basis for your evaluation. Need research for the functionality of a typical accounting system, Include what you find that such a system does as part of the justification of what level the system is in each of the categories.
