Excerpts

APPROACH One of the greatest challenges that we face in teaching information systems courses is how to keep pace in the class with what is happening out in the real world. Hardware, software, telecommunications, and networking equipment--all of it continues to become faster, cheaper, and better, and business organizations continue to adopt and adapt these new technologies rapidly. In fact, whereas a decade ago large businesses would spend two or three percent of their revenues on information technology, today, spending on information technology for many large businesses can range from seven to 10 percent of their revenue. Most important, organizations are now relying on that technology as a fundamental part of their business strategy and their competitiveness. As a result of this pervasiveness and the fast pace of technology change and use in organizations, teaching people about information systems has never been more valuable or challenging. Given the dynamic nature of information systems, and given that it is difficult to find introductory information systems textbooks that are both up-to-date and student-friendly, we wroteInformation Systems Todaywith three primary goals in mind. First, we wanted readers not only to learn about information systems, but also to feel as excited as we do about the field and about the amazing opportunities available in this area. Second, we did not simply want to spoon-feed students with the technical terms and the history of information systems. Instead, we want students to understand exactly what innovative organizations are doing with contemporary information systems and, more important, where things are headed. Third, we wanted to empower students with the essential knowledge they need to be successful in the use and understanding of information technology in their careers. To this end, we wroteInformation Systems Todayso that it is contemporary, fun to read, and useful, and includes the essential body of knowledge regarding information systems. APPROACH Information Systems Todayis primarily for the undergraduate introductory information systems course required of all business students. This course is typically offered in the junior year of four-year undergraduate programs and in the second year at two-year institutions. The introductory information systems course typically has a diverse audience of students majoring in many different areas, such as accounting, economics, finance, marketing, general management, human resource management, production and operations, international business, entrepreneurship, and information systems. Given the range of students taking this type of course, we have written this book so that it is a valuable guide to all business students and provides them with the essential information they need to know. Students majoring in areas outside of business may also attend the introductory information systems course. Therefore, this book has been written to appeal to a diverse audience. Information Systems Todaycan also be used for the introductory course offered at the graduate level--for example, in the first year of an MBA program. KEY FEATURES As authors, teachers, developers, and managers of information systems, we understand that in order for students to best learn about information systems with this book, they must be motivated to learn. To this end we have included a number of unique features to help students quickly and easily assess the true value of information systems and their impact on everyday life. We show how today's professionals are using information systems to help modern organizations become more efficient and competitive. Our focus is on the application of technology to real-world, contemporary situations. Below we describe each of the features that contribute to that focus. Cases: A Multitiered Approach O
