Management Information Systems, Fourth Edition, is a revision of our highest-level, most strategic, introduction to MIS text. What sets this book apart from others is its managerial focus and its unique case approach. Each of the book's five parts is begun with a Part Case, an extensive business case that engages the reader from the start. This case is then revisited at the start and end of each chapter. This provides a cohesive and real-world environment into which the reader can place all the MIS-related details information they are leaning. This case approach offers a context for the many and varied problems that businesses face everyday, and how information system can provide solutions. These cases are expanded upon and made interactive with the help of the companion Web site that accompanies this text, and gives students the chance to learn more about the cases, delve deeper into more MIS topics and also provide opportunities for more hands on practice. In addition, the new, fourth edition has been revised for currency throughout and offers some new end of chapter real world cases.
