Preface

Information technology and business are becoming inextricably interwoven. I don't think anybody can talk meaningfully about one without the talking about the other.

Bill Gates Microsoft 1

I'm not hiring MBA students for the technology you learn while in school, but for your ability to learn about, use and subsequently manage new technologies when you get out.

Give me a fish and I eat for a day; teach me to fish and I eat for a lifetime.

Proverb

Managers do not have the luxury of abdicating participation in decisions regarding information systems (IS). Managers who choose to do so risk limiting their future business options. IS are at the heart of virtually every business interaction, process, and decision, especially when the vast penetration of the Web over the last 20 years is considered. Mobile and social technologies have brought IS to an entirely new level within firms and between ,.J individuals in their personal lives. Managers who let someone else make decisions about their IS are letting someone else make decisions about the very foundation of their business. This is a textbook about managing and using information written for current and future managers as a way to introduce the broader implications of the impact of IS.

The goal of this book is to assist managers in becoming knowledgeable participants in IS decisions. Becoming a knowledgeable participant means learning the basics and feeling comfortable enough to ask questions. It does not mean having all the answers or having a deep understanding of all the technologies out in the world today. No text will provide managers everything they need to know to make important IS decisions. Some texts instruct on the basic technical background of IS. Others discuss applications and their life cycles. Some take a comprehensive view of the management information systems (MIS) field and offer readers snapshots of current systems along with chapters describing how those technologies are designed, used, and integrated into business life.

This book takes a different approach. It is intended to provide the reader a foundation of basic concepts relevant to using and managing information. This text is not intended to provide a comprehensive treatment on any one aspect of MIS, for certainly each aspect is itself a topic of many books. This text is not intended to provide readers enough technological knowledge to make them MIS experts. It is not intended to be a source of discussion of any particular technology. This text is written to help managers begin to form a point of view of how IS will help or hinder their organizations and create opportunities for them.

The idea for this text grew out of discussions with colleagues in the MIS area. Many faculties use a series of case studies, trade and popular press readings, and Web sites to teach their MIS courses. Others simply rely on one of the classic texts, which include dozens of pages of diagrams, frameworks, and technologies. The initial idea for this text emerged from a core MIS course taught at the business school at the University of Texas at Austin. That course was considered an "appetizer" course-a brief introduction into the world of MIS for MBA students. The course had two main topics: using information and managing information. At the time, there was no text like this

Preface • one; hence, students had to purchase thick reading packets made up of articles and case studies to provide them the basic concepts. The course was structured to provide general MBA students enough knowledge of the MIS field so that they could recognize opportunities to use the rapidly changing technologies available to them. The course was an appetizer to the menu of specialty courses, each of which went much more deeply into the various topics. But completion of the appetizer course meant that students were able to feel comfortable listening to, contributing to, and ultimately participating in IS decisions.

Today, many students are digital natives-people who have grown up using information technologies (IT) all of their lives. That means that students come to their courses with significantly more knowledge about things such as tablets, apps, personal computers, smartphones, texting, the Web, social networking, file downloading, online purchasing, and social media than their counterparts in school just a few years ago. This is a significant trend that is projected to continue; students will be increasingly knowledgeable the personal use of technologies. That knowledge has begun to change the corporate environment. Today's digital natives expect to find in corporations IS that provide at least the functionality they have at home. At the same time, these users expect to be able to work in ways that take advantage of the technologies they have grown to depend on for social interaction, collaboration, and innovation. We believe that the basic foundation is still needed for managing and using IS, but we understand that the assumptions and knowledge base of today's students is significantly different.

Also different today is the vast amount of information amassed by firms, sometimes called the "big data" prob- lem. Organizations have figured out that there is an enormous amount of data around their processes, their interac- tions with customers, their products, and their suppliers. These organizations also recognize that with the increase in communities and social interactions on the Web, there is additional pressure to collect and analyze vast amounts of unstructured information contained in these conversations to identify trends, needs, and projections. We believe that today's managers face an increasing amount of pressure to understand what is being said by those inside and outside their corporations and to join those conversations reasonably and responsibly. That is significantly different from just a few years ago.

This book includes an introduction, 13 chapters of text and mini cases, and a set of case studies, supplemental readings, and teaching support on a community hub at http://pearlsonandsaunders.com. The Hub provides faculty members who adopt the text additional resources organized by chapter, including recent news items with teaching suggestions, videos with usage suggestions, blog posts and discussions from the community, class activities, addi- tional cases, cartoons, and more. Supplemental materials, including longer cases from all over the globe, can be found on the Web. Please visit http://www.wiley.com/college/pearlson or the Hub for more information.

The introduction to this text defends the argument presented in this preface that managers must be knowledge- able participants in making IS decisions. The first few chapters build a basic framework of relationships among business strategy, IS strategy, and organizational strategy and explore the links among them. The strategy chapters are followed by ones on work design and business processes that discuss the use of IS. General managers also need some foundation on how IT is managed if they are to successfully discuss their next business needs with IT pro- fessionals who can help them. Therefore, the remaining chapters describe the basics of information architecture and infrastructure, IT security, the business of IT, the governance of the IS organization, IS sourcing, project management, business analytics, and relevant ethical issues.

Given the acceleration of security breaches, readers will find a new chapter on IS security in this sixth edition of the text. Also, the material on analytics and "big data" has been extensively updated to reflect the growing impor- tance of the topic. Further, the chapter on work design has been reorganized and extensively revised. Each of the other chapters has been revised with newer concepts added, discussions of more current topics fleshed out, and old, outdated topics removed or at least their discussion shortened.

Similar to the fifth edition, every chapter begins with a navigation "box" to help the reader understand the flow and key topics of the chapter. Further, most chapters continue to have a Social Business Lens or a Geographic Lens feature. The Social Business Lens feature reflects on an issue related to the chapter's main topic but is enabled by or fundamental to using social technologies in the enterprise. The Geographic Lens feature offers a single idea about a global issue related to the chapter's main topic.

No text in the field of MIS is completely current. The process of writing the text coupled with the publication process makes a book somewhat out-of-date prior to delivery to its audience. With that in mind, this text is written

• Preface to summarize the "timeless" elements of using and managing information. Although this text is complete in and of itself, learning is enhanced by combining the chapters with the most current readings and cases. Faculty are encouraged to read the news items on the faculty Hub before each class in case one might be relevant to the topic of the day. Students are encouraged to search the Web for examples related to topics and current events and bring them into the discussions of the issues at hand. The format of each chapter begins with a navigational guide, a short case study, and the basic language for a set of important management issues. These are followed by a set of managerial concerns related to the topic. The chapter concludes with a summary, key terms, a set of discussion questions, and case studies.

Who should read this book? General managers interested in participating in IS decisions will find this a good reference resource for the language and concepts of IS. Managers in the IS field will find the book a good resource for beginning to understand the general manager's view of how IS affect business decisions. And IS students will be able to use the book's readings and concepts as the beginning in their journey to become informed and success- ful businesspeople.

The information revolution is here. Where do you fit in?

Acknowledgments

Books of this nature are written only with the support of many individuals. We would like to personally thank several individuals who helped with this text. Although we've made every attempt to include everyone who helped make this book a reality, there is always the possibility of unintentionally leaving some out. We apologize in advance if that is the case here.

Thank you goes to Dr. William Turner of LeftFour, in Austin, Texas, for help with the infrastructure and architecture concepts and to Alan Shimel, Editor-in-Chief at DevOps.com for initial ideas for the new security chapter.

We also want to acknowledge and thank pbwiki.com. Without its incredible and free wiki, we would have been relegated to e-mailing drafts of chapters back and forth, or saving countless files in an external drop box without any opportunity to include explanations or status messages. For this edition, as with earlier editions, we wanted to use Web 2.0 tools as we wrote about them. We found that having used the wiki for our previous editions, we were able to get up and running much faster than if we had to start over without the platform.

We have been blessed with the help of our colleagues in this and in previous editions of the book. They helped us by writing cases and reviewing the text. Our thanks continue to go out to Jonathan Trower, Espen Andersen, Janis Gogan, Ashok Rho, Yvonne Lederer Antonucci, E. Jose Proenca, Bruce Rollier, Dave Oliver, Celia Romm, Ed Watson, D. Guiter, S. Vaught, Kala Saravanamuthu, Ron Murch, John Greenwod, Tom Rohleder, Sam Lubbe, Thomas Kern, Mark Dekker, Anne Rutkowski, Kathy Hurtt, Kay Nelson, Janice Sipior, Craig Tidwell, and John Butler. Although we cannot thank them by name, we also greatly appreciate the comments of the anonymous reviewers who have made a mark on this edition.

The book would not have been started were it not for the initial suggestion of a wonderful editor in 1999 at John Wiley & Sons, Beth Lang Golub. Her persistence and patience helped shepherd this book through many previous editions. We also appreciate the help of our current editor, Lise Johnson. Special thanks go to Jane Miller, Gladys Soto, Loganathan Kandan, and the conscientious JaNoel Lowe who very patiently helped us through the revision process. We also appreciate the help of all the staff at Wiley who have made this edition a reality.

We would be remiss if we did not also thank Lars Linden for the work he has done on the Pearlson and Saunders Faculty Hub for this book. Our vision included a Web-based community for discussing teaching ideas and post- ing current articles that supplement this text. Lars made that vision into a reality starting with the last edition and continuing through the present. Thank you, Lars!

From Keri: Thank you to my husband, Yale, and my daughter, Hana, a business and computer science student at Tulane University. Writing a book like this happens in the white space of our lives-the time in between everything else going on. This edition came due at a particularly frenetic time, but they listened to ideas, made suggestions, and celebrated the book's completion with us. I know how lucky I am to have this family. I love you guys!

From Carol: I would like to thank the Dr. Theo and Friedl Schoeller Research Center of Business and Society for their generous support of my research. Rusty, thank you for being my compass and my release valve. I couldn't do it without you. Paraphrasing the words of an Alan Jackson song ("Work in Progress"): I may not be what you want me to be, but I'm trying really hard. Just be patient because I'm a work in progress. I love you, Kristin, Russell, and Janel very much!

From Dennis: Thanks to my terrific family: my wife Carole, my daughters Christy and Lauren, and my grand- daughter Gracie. Also thanks to Matt and Jacob, two lovable guys who take wonderful care of my daughters. Finally, thanks to our parents and sisters' families. We are also blessed with a large number of great, caring neighbors whom we see quite often. I love you all, and you make it all worthwhile!
