Preface

What’s New in the 2nd Edition The information systems field is fast-moving, and this 2nd edition introduces and updates many important concepts and technologies. We changed the title to Introduction to Information Systems to better reflect the contents and the course. This edition includes more figures, graphs, and tables to illustrate topics in visual ways, and the references, examples, data, and case studies are all updated. Larger fonts are used for the tables, and the text portion of each chapter has been shortened, most notably by tightening up the chapter introductions to get into the chapter content more quickly. The online simula- tions are converted to HTML5 so they are accessible from iPads and iPhones, and the scores go into the gradebook.

Major new features for the 2nd edition include the following:

▶ Extended coverage of big data and the technologies used to store and analyze it has been added, along with a new “Ethical Factor” box that explores the ethics of big data.

▶ Expanded discussion of mobile devices and m-commerce is featured in Chapter 6, including a review of evolving mobile payment technologies using near field com- munications and strategies for mobile-friendly software development.

▶ The “Internet of Things” is highlighted in several chapters because of its growing impact on network architecture and bandwidth, and its rapidly increasing role in data collection, analysis, privacy, and surveillance.

▶ The 2nd edition expands the discussion of cloud computing, personal clouds, mobil- ity, and the BYOD (bring your own device) trend, especially as they affect strategic planning for the organization.

▶ A new comprehensive case study at the end of the text charts Apple’s disruptive inno- vations, and encourages students to predict the company’s future business strategy.

▶ Twitter’s role in social TV and the “multiscreening” phenomenon are featured in a new case study about Nielsen’s program rating system, so students see how tweeting fits into the entertainment industry’s strategies.

To the Student Any college student thinking about the job market can’t help but notice how valuable it is to have skills related to information systems. In this course you will learn what infor- mation systems are all about and why they are so fundamental to business and society. It will be an exciting journey, filled with revelations about business strategies, technology trends and innovations, and also tips that will help you work smarter as a student. Here are the main features of this text and its supplements:

Learn by Doing: The Interactive, Online Role-Playing Simulations A course on information systems should tap their power for active, experiential learning. This text includes interactive role-playing simulations in MyMISLab™ (mymislab.com) in which students can apply their knowledge and actually experience what each chapter is about, not just memorize key terms and concepts. You will enter realistic and often tense situations, interacting with the characters via a simulated smartphone or laptop, and using email, text messages, web conferencing, video chat, voicemail, dashboards, ordering screens, and other applications. Each simulation is scored and students receive extensive feedback on the choices they make. Each one also includes key terms from the chapter (with rollover definitions) so you see how they are used in context, which will help you more easily remember their meanings.

The simulations bring the chapter alive, as you enter authentic settings in which people struggle to solve a problem involving information systems. Some examples:

▶ In World of Mammals (Chapter 1), you help the harried director of a wild ani- mal preserve interview candidates for the CIO position, after the former CIO leaves abruptly. What skills does a CIO need? What kind of experience would fit best?

▶ Chocolate Lovers Unite (Chapter 7) challenges you to resolve a heated debate over which online marketing pitch works best by conducting tests, analyzing the results, and drawing on data-driven decision making.

▶ In Green Wheeling, the simulation on software development and procurement (Chapter 11), you join a task force charged with replacing a college’s obsolete fund- raising system. You and your team members weigh the pros and cons of “build” or “buy,” and you will see how the outcome can change based on your decisions.
