Columbia Southern University Management Information Systems Case Study

Instructions The case studies below provide you with an opportunity to critically analyze events that are taking place in real-life businesses. This helps to develop your critical thinking and research skills as you research each of these scenarios. For this assignment, you will review four case studies, one from Chapter 9, one from Chapter 10, one from Chapter 11, and one from Chapter 12. Then, you will evaluate the studies and respond to each of the questions below, using both critical thinking and theory as well as supporting documentation. In Chapter 9, read the case study ”Soma Bay Prospers with ERP in the Cloud” on pages 345–346 of the textbook. Then, address the prompts below. Describe the problem that Soma Bay encountered in this case study. Why was an enterprise resource planning (ERP) system needed to solve the problem? What are some challenges that this ERP system poses? Will this ERP system help the company achieve operational excellence? Why, or why not? In Chapter 10, read the case study “A Nasty Ending for Nasty Gal” on pages 414–416 of the textbook. Then, answer the questions below. Was it a good idea to use social media as a marketing and social tool for Nasty Gal? Why, or why not? What were the management, organization, and technological issues that contributed to the failure of Nasty Gal? If you were hired as the new chief executive officer (CEO) of Nasty Gal, what would you have done differently to keep the company from filing for bankruptcy? In Chapter 11, read the case study “Can Cars Drive Themselves–And Should They?” on pages 453–455 of the textbook. Then, address the prompts below. Discuss some benefits and disadvantages of automated automobiles. Be sure to include a discussion of ethical and social issues presented by automated automobiles. If you were the CEO of a major auto manufacturer, would you invest resources in the development and marketing of automated automobiles? Why, or why not? In Chapter 12, read the case study “Anthem Benefits from More Business Intelligence” on pages 480-481 of the textbook. Then, address the prompts below. Discuss the problem with the old human resources (HR) system at Anthem. Describe the new People Data Central (PDC) portal adopted by Anthem.

CSU Common Method of Putting out A Fire Discussion

Instructions Recently, there has been discussion over the importance of not advancing into a fire until you have cooled the smoke with a wetting agent. The theory is that once the smoke is cooled, reheating of the combustibles in the compartment will be slower, as the cooled smoke can no longer produce the radiative heat conditions to support flashover. Reportedly, smoke conditions will not worsen, contrary to what has been taught in many fire academies. What has been your observation, experience, reflection, or reasoning for wetting agents or water on cooling smoke? Do you support this? Why, or why not?
