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

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 fi rms and between 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) fi eld 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

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
fpref.indd 5 11/27/2015 4:21:12 PMhttp://pearlsonandsaunders.comhttp://www.wiley.com/college/pearlson
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?

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 fi les 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 terrifi c 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!

Why do managers need to understand and participate in the information systems decisions of their organizations? After all, most corporations maintain entire departments dedicated to the management of information systems (IS). These departments are staffed with highly skilled professionals devoted to the fi eld of technology. Shouldn’t managers rely on experts to analyze all the aspects of IS and to make the best decisions for the organization? The answer to that question is an emphatic “no.”
Managing information is a critical skill for success in today ’ s business environment. All decisions made by companies involve, at some level, the management and use of IS and the interpretation of data from the business and its environment. Managers today need to know about their organization ’ s capabilities and uses of information as much as they need to understand how to obtain and budget fi nancial resources. The ubiquity of personal devices such as smart phones, laptops, and tablets and of access to apps within corporations and externally over the Internet, highlights this fact. Today ’ s technologies form the backbone for virtually all business models. This backbone easily crosses oceans, adding the need for a global competency to the manager ’ s skill set. Further, the proliferation of supply chain partnerships and the vast amount of technology available to individuals outside of the corporation have extended the urgent need for business managers to be involved in information systems decisions. In addition, the availability of seemingly free (or at least very inexpensive) appli- cations, collaboration tools, and innovation engines in the consumer arena has put powerful tools in everyone ’ s hands, increasing the diffi culty of ensuring that corporate systems are robust, secure, and protected. A manager who doesn ’ t understand the basics of managing and using information can ’ t be successful in this business environment.
The majority of U.S. adults own a smart phone and access online apps. According to the Pew Research Center , in 2014, 90% of U.S. adults had a cell phone of some kind, and 87% of American adults used the Internet. 1 Essentially the use of these types of devices implies that individuals now manage a “personal IS” and make decisions about usage, data, and applications. Doesn ’ t that give them insight into managing information systems in corporations? Students often think they are experts in corporate IS because of their personal experience with technology. Although there is some truth in that perspective, it ’ s a very dangerous perspective for managers to take. Certainly knowing about interesting apps, being able to use a variety of technologies for different personal purposes, and being familiar with the ups and downs of networking for their personal information systems pro- vide some experience that is useful in the corporate setting. But in a corporate setting, information systems must be enterprise‐ready. They must be scalable for a large number of employees; they must be delivered in an appropriate manner for the enterprise; they must be managed with corpo- rate guidelines and appropriate governmental regulations in mind. Issues like security, privacy, risk, support, and architecture take on a new meaning within an enterprise, and someone has to manage them. Enterprise‐level management and use of information systems require a unique perspective and a different skill set.

Consider the now‐historic rise of companies such as Amazon.com, Google, and Zappos. Amazon.com began as an online bookseller and rapidly outpaced traditional brick‐and‐mortar businesses like Barnes and Noble, Borders, and Waterstones. Management at the traditional companies responded by having their IS support personnel build Web sites to compete. But upstart Amazon.com moved ahead, keeping its leadership position on the Web by lever- aging its business model into other marketplaces, such as music, electronics, health and beauty products, lawn and garden products, auctions, tools and hardware, and more. It cleared the profitability hurdle by achieving a good mix of IS and business basics: capitalizing on operational efficiencies derived from inventory software and smarter storage, cost cutting, and effectively partnering with such companies as Toys “R” Us Inc. and Target Corporation.2 More recently, Amazon.com changed the basis of competition in another market, but this time it was the Web ser- vices business. Amazon.com Web services offers clients the extensive technology platform used for Amazon.com but in an on‐demand fashion for developing and running the client’s own applications. Shoe retailer Zappos.com challenged Amazon’s business model, in part by coupling a social business strategy with exemplary service and sales. It was so successful that Amazon.com bought Zappos.
Likewise, Google built a business that is revolutionizing the way information is found. Google began in 1999 as a basic search company but its managers quickly learned that its unique business model could be leveraged for future success in seemingly unrelated areas. The company changed the way people think about Web content by making it available in a searchable format with an incredibly fast response time and in a host of languages. Further, Google’s keyword‐targeted advertising program revolutionized the way companies advertise. Then Google expanded, offering a suite of Web‐based applications, such as calendaring, office tools, e‐mail, collaboration, shopping, and maps and then enhanced the applications further by combining them with social tools to increase collaboration. Google Drive is one of the most popular file‐sharing tools and Gmail one of the most popular email apps. In 2015, Google’s mission was to “organize the world’s information and make it universally accessible and useful.” It is offering its customers very inexpensive fiber connections. In so doing, Google further expanded into infrastructure and on‐demand services.3
These and other online businesses are able to succeed where traditional companies have not, in part because their management understood the power of information, IS, and the Web. These exemplary online businesses aren’t suc- ceeding because their managers could build Web pages or assemble an IS network. Rather, the executives in these new businesses understand the fundamentals of managing and using information and can marry that knowledge with a sound, unique business vision to dominate their intended market spaces.
The goal of this book is to provide the foundation to help the general business manager become a knowledge- able participant in IS decisions because any IS decision in which the manager doesn’t participate can greatly affect the organization’s ability to succeed in the future. This introduction outlines the fundamental reasons for taking the initiative to participate in IS decisions. Moreover, because effective participation requires a unique set of manage- rial skills, this introduction identifies the most important ones. These skills are helpful for making both IS decisions and all business decisions. We describe how managers should participate in the decision‐making process. Finally, this introduction presents relevant models for understanding the nature of business and information systems. These models provide a framework for the discussions that follow in subsequent chapters.
The Case for Participating in Decisions about Information Systems In today’s business environment, maintaining a back‐office view of technology is certain to cost market share and could ultimately lead to the failure of the organization. Managers who claim ignorance of IS can damage their reputation. Technology has become entwined with all the classic functions of business—operations, marketing, accounting, finance—to such an extent that understanding its role is necessary for making intelligent and effec- tive decisions about any of them. Furthermore, a general understanding of key IS concepts is possible without the extensive technological knowledge required just a few years ago. Most managers today have personal technology

3The Case for Participating in Decisions about Information Systems
such as a smart phone or tablet that is more functional than many corporate‐supported personal computers provided by enterprises just a few years ago. In fact, the proliferation of personal technologies makes everyone a “pseudo‐ expert.” Each individual must manage applications on smart phones, make decisions about applications to purchase, and procure technical support when the systems fail. Finally, with the robust number of consumer applications available on the Web, many decisions historically made by the IS group are increasingly being made by individuals outside that group, sometimes to the detriment of corporate objectives.
Therefore, understanding basic fundamentals about using and managing information is worth the investment of time. The reasons for this investment are summarized in Figure I-1 and are discussed next.
A Business View of Critical Resources Information technology (IT) is a critical resource for today’s businesses. It both supports and consumes a significant amount of an organization’s resources. Just like the other three major types of business resources—people, money, and machines—it needs to be managed wisely.
IT spending represents a significant portion of corporate budgets. Worldwide IT spending topped $3.7 trillion in 2014. It is projected to continue to increase.4 A Gartner study of where this money goes groups spending into five categories including devices (e.g., PCs, tablets, and mobile phones), data center systems (e.g., network equipment, servers, and storage equipment), enterprise software and apps (e.g., companywide software applications), IT ser- vices (e.g., support and consulting services), and telecommunications (e.g., the expenses paid to vendors for voice and data services).
Resources must return value, or they will be invested elsewhere. The business manager, not the IS specialist, decides which activities receive funding, estimates the risk associated with the investment, and develops metrics for evaluating the investment’s performance. Therefore, the business manager needs a basic grounding in managing and using information. On the flip side, IS managers need a business view to be able to explain how technology impacts the business and what its trade‐offs are.
People and Technology Work Together In addition to financial issues, managers must know how to mesh technology and people to create effective work processes. Collaboration is increasingly common, especially with the rise of social networking. Companies are reaching out to individual customers using social technologies such as Facebook, Twitter, Reddit, Renren, YouTube, and numerous other tools. In fact, Web 2.0 describes the use of the World Wide Web applications that incorporate information sharing, user‐centered design, interoperability, and collaboration among users. Technology facilitates

the work that people do and the way they interact with each other. Appropriately incorporating IS into the design of a business model enables managers to focus their time and resources on issues that bear directly on customer satisfaction and other revenue‐ and profit‐generating activities.
Adding a new IS to an existing organization, however, requires the ability to manage change. Skilled business managers must balance the benefits of introducing new technology with the costs associated with changing the existing behaviors of people in the workplace. There are many choices of technology solutions, each with a different impact. Managers’ decisions must incorporate a clear understanding of the consequences. Making this assessment doesn’t require detailed technical knowledge. It does require an understanding of short‐term and long‐term con- sequences risk mitigation, and why adopting new technology may be more appropriate in some instances than in others. Understanding these issues also helps managers know when it may prove effective to replace people with technology at certain steps in a process.
Integrating Business with Information Systems IS are integrated with almost every aspect of business and have been for quite some time. For example, the CTO of @WalmartLabs, Jeremy King, wrote in a blog,
There used to be a big distinction between tech companies: those that develop enterprise technology for businesses, and the global companies that depend on those products. But that distinction is now diminishing for this simple reason: every global company is becoming a tech company. . . . we’re seeing technology as a critical component for business success.5
Walmart built platforms to support all of its ecommerce and digital shopping experiences around the world. Walmart’s teams created a new search engine to enable engaging and efficient ways for on‐line customers to find items in inventory. IS placed information in the hands of Walmart associates so that decisions could be made closer to the customer. IS simplified organizational activities and processes such as moving goods, stocking shelves, and communicating with suppliers. For example, handheld scanners provide floor associates with immediate and real‐ time access to inventory in their store and the ability to locate items in surrounding stores, if necessary.
Opportunities and New Strategies Derived from Rapid Changes in Technology The proliferation of new technologies creates a business environment filled with opportunities. The rate of adop- tion of these new technologies has increased due in part to the changing demographics of the workforce and the integration of “digital natives,” individuals whose entire lives have been lived in an era with Internet availability. Therefore digital natives are completely fluent in the use of personal technologies and the Web. Even today, inno- vative uses of the Internet produce new types of online businesses that keep every manager and executive on alert. New business opportunities spring up with little advance warning. The manager’s role is to frame these oppor- tunities so that others can understand them, evaluate them against existing business needs and choices, and then pursue those that fit with an articulated business strategy. The quality of the information at hand affects the quality of both decisions and their implementation. Managers must develop an understanding of what information is cru- cial to the decisions, how to get it, and how to use it. They must lead the changes driven by IS.
Competitive Challenges Competitors come from both expected and unexpected places. General managers are in the best position to see the emerging threats and utilize IS effectively to combat ever‐changing competitive challenges. Further, general man- agers are often called on to demonstrate a clear understanding of how their own technology programs and products

5What If a Manager Doesn’t Participate?
compare with those of their competitors. A deep understanding of the capabilities of the organization coupled with existing IS can create competitive advantages and change the competitive landscape for the entire industry.
Customer Pull With the emergence of social networks like Facebook, microblogs like Twitter, and other Web applications like Yelp, businesses have had to redesign their existing business models to account for the change in power now wielded by customers and others in their communities. Social media and other web apps have given powerful voices to customers and communities, and businesses must listen. Redesigning the customer experience when inter- acting with a company is paramount for many managers and the key driver is IS. Social IT enables new and often deeper relationships with a large number of customers, and companies are learning how to integrate and leverage this capability into existing and new business models.
Data‐Driven Decision Making Managers are increasingly using evidence‐based management to make decisions based on data gathered from experiments, internal files, and other relevant sources. Data‐driven decision making, based on new techniques for analytics, data management, and business intelligence, has taken on increased importance. Social media have cre- ated a rich stream of real‐time data that gives managers increased insights to the impact of decisions much faster than traditional systems. Mid‐course corrections are much easier to make. Predictive and prescriptive analytics give suggestions that are eerily close to what happens. Big data stores can be mined for insights that were unavailable with traditional IS, creating competitive advantage for companies with the right tools and techniques.
Securing Key Assets As the use of the Internet grows, so does the opportunity for new and unforeseen threats to company assets. Taking measures to ensure the security of these assets is increasingly important. But decisions about security measures also impact the way IS can be used. It’s possible to put so much security around IT assets that they are locked down in a manner that gets in the way of business. At the same time, too little security opens up the possibility of theft, hacking, phishing, and other Web‐based mischief that can disrupt business. Managers must be involved in decisions about risk and security to ensure that business operations are in sync with the resulting security measures.
What If a Manager Doesn’t Participate? Decisions about IS directly affect the profits of a business. The basic formula Profit = Revenue − Expenses can be used to evaluate the impact of these decisions. Adopting the wrong technologies can cause a company to miss business opportunities and any revenues those opportunities would generate. For example, inadequate IS can cause a breakdown in servicing customers, which hurts sales. Poorly deployed social IT resources can badly damage the reputation of a strong brand. On the expense side, a miscalculated investment in technology can lead to over- spending and excess capacity or underspending and restricted opportunity. Inefficient business processes sustained by ill‐fitting IS also increase expenses. Lags in implementation or poor process adaptation reduces profits and there- fore growth. IS decisions can dramatically affect the bottom line.
Failure to consider IS strategy when planning business strategy and organizational strategy leads to one of three business consequences: (1) IS that fail to support business goals, (2) IS that fail to support organizational systems, and (3) a misalignment between business goals and organizational capabilities. These consequences are discussed briefly in the following section and in more detail in later chapters. The driving questions to consider are the poten- tial effects on an organization’s ability to achieve its business goals. How will the consequences impact the way people work? Will the organization still be able to implement its business strategy?
cintro.indd 5 11/26/2015 7:38:29 PM
Information Systems Must Support Business Goals IS represent a major investment for any firm in today’s business environment. Yet poorly chosen IS can actually become an obstacle to achieving business goals. The results can be disastrous if the systems do not allow the orga- nization to realize its goals. When IS lack the capacity needed to collect, store, and transfer critical information for the business, decisions can be impacted and options limited. Customers will be dissatisfied or even lost. Production costs may be excessive. Worst of all, management may not be able to pursue desired business directions that are blocked by inappropriate IS. Victoria’s Secret experienced this problem when a Superbowl ad promoting an online fashion show generated so many inquiries to its Web site that the Web site crashed. Spending large amounts of money on the advertisement was wasted when potential customers could not access the site. Likewise, Toys “R” Us experienced a similar calamity when its well‐publicized Web site was unable to process and fulfill orders fast enough one holiday season. It not only lost those customers, but it also had a major customer‐relations issue to manage as a result.
Information Systems Must Support Organizational Systems Organizational systems represent the fundamental elements of a business—its people, work processes, tasks, struc- ture, and control systems—and the plan that enables them to work efficiently to achieve business goals. If the company’s IS fail to support its organizational systems, the result is a misalignment of the resources needed to achieve its goals. For example, it seems odd to think that a manager might add functionality to a corporate Web site without providing the training the employees need to use the tool effectively. Yet, this mistake—and many more costly ones—occurs in businesses every day. Managers make major IS decisions without informing all the staff of resulting changes in their daily work. For example, an enterprise resource planning (ERP) system often dictates how many business processes are executed and the organizational systems must change to reflect the new processes. Deploying technology without thinking through how it actually will be used in the organization—who will use it, how they will use it, and how to make sure the applications chosen will actually accomplish what is intended—results in significant expense. In another example, a company may decide to block access to the Internet, thinking that it is prohibiting employees from accessing offensive or unsecure sites. But that decision also means that employees can’t access social networking sites that may be useful for collaboration or other Web‐based appli- cations that may offer functionality to make the business more efficient.
The general manager, who, after all, is charged with ensuring that company resources are used effectively, must guarantee that the company’s IS support its organizational systems and that changes made in one system are reflected in the other. For example, a company that plans to allow employees to work remotely needs an information system strategy compatible with its organizational strategy. Desktop PCs located within the corporate office aren’t the right solution for a telecommuting organization. Instead, laptop computers or tablets with applications that are accessible online anywhere and anytime and networks that facilitate information sharing are needed. Employees may want to use tablets or smart phones remotely, too, and those entail a different set of IS processes. If the orga- nization allows the purchase of only desktop PCs and builds systems accessible from desks within the office, the telecommuting program is doomed to failure.
Skills Needed to Participate Effectively in Information Technology Decisions Participating in IT decisions means bringing a clear set of skills to the table. All managers are asked to take on tasks that require different skills at different times. Those tasks can be divided into three types: visionary tasks, or those that provide leadership and direction for the group; informational/interpersonal tasks, or those that provide information and knowledge the group needs to be successful; and structural tasks, those that organize the group. Figure I-2 lists basic skills required of managers who wish to participate successfully in key IT decisions. Not only does this list emphasize understanding, organizing, planning, and solving the business needs of the organization, but also it is an excellent checklist for all managers’ professional growth.

7Skills Needed to Participate Effectively in Information Technology Decisions
These skills may not look much different from those required of any successful manager, which is the main point of this book: General managers can be successful participants in IS decisions without an extensive technical background. General managers who understand a basic set of IS concepts and who have outstanding managerial skills, such as those listed in Figure I-2, are ready for the digital economy.
How to Participate in Information Systems Decisions Technical wizardry isn’t required to become a knowledgeable participant in the IS decisions of a business. Man- agers need curiosity, creativity, and the confidence to ask questions in order to learn and understand. A solid frame- work that identifies key management issues and relates them to aspects of IS provides the background needed to participate in business IS decisions.
The goal of this book is to provide that framework. The way in which managers use and manage information is directly linked to business goals and the business strategy driving both organizational and IS decisions. Aligning business and IS decisions is critical. Business, organizational, and information strategies are fundamentally linked in what is called the Information Systems Strategy Triangle, discussed in the next chapter. Failing to understand this relationship is detrimental to a business. Failing to plan for the consequences in all three areas can cost a manager his or her job. This book provides a foundation for understanding business issues related to IS from a managerial perspective.
Organization of the Book To be knowledgeable participants, managers must know about both using and managing information. The first five chapters offer basic frameworks to make this understanding easier. Chapter 1 uses the Information Systems Strategy Triangle framework to discuss alignment of IS and the business. This chapter also provides a brief over- view of relevant frameworks for business strategy and organizational strategy. It is provided as background for those who have not formally studied organization theory or business strategy. For those who have studied these areas, this chapter is a brief refresher of major concepts used throughout the remaining chapters of the book.

Subsequent chapters provide frameworks and sets of examples for understanding the links between IS and business strategy (Chapter 2), links between IS and organizational strategy (Chapter 3), collaboration and individual work (Chapter 4), and business processes (Chapter 5).
The rest of the text covers issues related to the business manager’s role in managing IS itself. These chapters are the building blocks of an IS strategy. Chapter 6 provides a framework for understanding the four components of IS architecture: hardware, software, networks, and data. Chapter 7 discusses how managers might participate in decisions about IS security. Chapter 8 focuses on the business of IT with a look at IS organization, funding models, portfolios, and monitoring options. Chapter 9 describes the governance of IS resources. Chapter 10 explores sourc- ing and how companies provision IS resources. Chapter 11 focuses on project and change management. Chapter 12 concerns business intelligence, knowledge management, and analytics and provides an overview of how companies manage knowledge and create a competitive advantage using business analytics. And finally, Chapter 13 discusses the ethical use of information and privacy.
Basic Assumptions Every book is based on certain assumptions, and understanding those assumptions makes a difference in interpret- ing the text. The first assumption made by this text is that managers must be knowledgeable participants in the IS decisions made within and affecting their organizations. That means that the general manager must develop a basic understanding of the business and technology issues related to IS. Because technology changes rapidly, this text also assumes that today’s technology is different from yesterday’s technology. In fact, the technology available to readers of this text today might even differ significantly from that available when the text was being written. Therefore, this text focuses on generic concepts that are, to the extent possible, technology independent. It provides frameworks on which to hang more up‐to‐the‐minute technological evolutions and revolutions, such as new uses of the Web, new social tools, or new cloud‐based services. We assume that the reader will supplement the discussions of this text with current case studies and up‐to‐date information about the latest technology.
A second, perhaps controversial, assumption is that the roles of a general manager and of an IS manager require different skill sets and levels of technical competency. General managers must have a basic understanding of IS in order to be a knowledgeable participant in business decisions. Without that level of understanding, their decisions may have serious negative implications for the business. On the other hand, IS managers must have more in‐depth knowledge of technology so they can partner with general managers who will use the IS. As digital natives take on increasingly more managerial roles in corporations, this second assumption may change—all managers may need deeper technical understanding. But for this text, we assume a different, more technical skill set for the IS manager and we do not attempt to provide that here.
Assumptions about Management Although many books have been written describing the activities of managers, organizational theorist Henry Mintzberg offers a view that works especially well with a perspective relevant to IS management. Mintzberg’s model describes management in behavioral terms by categorizing the three major roles a manager fills: interper- sonal, informational, and decisional (see Figure I-3). This model is useful because it considers the chaotic nature of the environment in which managers actually work. Managers rarely have time to be reflective in their approaches to problems. They work at an unrelenting pace, and their activities are brief and often interrupted. Thus, quality information becomes even more crucial to effective decision making. The classic view is often seen as a tactical approach to management, whereas some describe Mintzberg’s view as more strategic.
Assumptions about Business Everyone has an internal understanding of what constitutes a business, which is based on readings and experi- ences with different firms. This understanding forms a model that provides the basis for comprehending actions, interpreting decisions, and communicating ideas. Managers use their internal model to make sense of otherwise

chaotic and random activities. This book uses several conceptual models of business. Some take a functional view and others take a process view.
Functional View The classical view of a business is based on the functions that people perform, such as accounting, finance, marketing, operations, and human resources. The business organizes around these functions to coordinate them and to gain economies of scale within specialized sets of tasks. Information first flows vertically up and down between line positions and management; after analysis, it may be transmitted across other functions for use elsewhere in the company (see Figure I-4).
Process View Michael Porter of Harvard Business School describes a business in terms of the primary and support activities that are performed to create, deliver, and support a product or service. The primary activities are not limited to specific functions, but rather are cross‐functional processes (see Figure I-5). For example, an accounts payable process
