Overview This appendix presents seven case studies that illustrate various problems that arise in MIS. Remember that most problems can affect many areas of a company. Any realistic situation will have many different problems or symptoms. It is important to search for the causes of the symptoms. Chapter 3 presented some hints and techniques that can be used to approach case problems and look for causes. One useful step is to try to classify the level of the problem: operations, tactical, or strategic. Although many problems will affect all three areas, the fundamental causes often focus at one level. When you are searching for solutions to business problems and cases, it is often helpful to examine what other companies have done in similar situations. The previous chapters had several examples of cases and applications that might prove useful. Also, business and MIS publications continually provide examples of problems faced by existing firms and of innovative solutions. Remember that business problems rarely have a single correct answer. There is always room for creativity and innovation. Just make sure that your solution will actually solve the main problems. Also, think about the implications of any solutions. Will it cause more problems than it solves? Virtually any MIS case could be solved with the simple statement that the firm needs more computers. However, a one-line statement is not a very useful plan. In any business setting, you not only have to find an answer, you must also persuade others (executives) that your answer is the best alternative. Additionally, a good solution will contain an implementation plan—perhaps with a timetable that delineates each step of the process. 1
