Pa r t 1PA R T OV E R V I E WThis introductory part sets up theoverall context for the book. Itcontains the following elements: A definition of the key terminologyused throughout the book An overview of the evolution ofe-business over time A discussion of how concepts andcases contribute to buildinge-business competenceINTRODUCTIONThe goal of this introductory part is to provide a guide and acontext for the content of the book. Chapter 1 starts outwith definitions of the most important terms used in thebook, such as e-business, electronic commerce and mobilee-commerce, and the concepts of strategy and value creation. It then provides an overview of the evolution ofe-business over the past decade and recognizes four distinctperiods: (1) the grassroots of e-business, (2) the rise of theInternet, (3) the crash, and (4) the consolidation phase.Chapter 2 shows how cases and concepts help to enhancecreativity and analytic abilities, leading to increased overalle-business competence.

Define the concept of strategy and differentiate between different levels ofstrategy development. Describe the life cycle of technological revolutions and illustrate it throughdifferent historic examples. Recognize the four main periods of the e-business evolution over the pastdecade and explain the peculiar characteristics of each period.

Part 1 · IntroductionINTRODUCTIONThe purpose of this chapter is to set up the stage for the remainder of the book.Since, due to the relative novelty of e-business, there is not yet a clear and sharedview of what this domain entails, we first want to ensure a common understanding ofthe key terminology used throughout the book. Section 1.1 includes the definition ofe-business-related terms and concepts as well as some strategy-specific perspectives.Following that, Section 1.2 provides a framework that describes the typical stages oftechnological revolutions and positions the evolution of electronic business duringthe past decade within this framework.1.1 Key terminology1.1.1 e-Business1The term ‘e-business’ is defined here as the use of electronic means to conduct anorganization’s business internally and/or externally. Internal e-business activitiesinclude the linking of an organization’s employees with each other through anintranet to improve information sharing, facilitate knowledge dissemination, andsupport management reporting. E-business activities also include supporting aftersales service activities and collaborating with business partners, e.g., conducting jointresearch, developing a new product, and formulating a sales promotion.In spite of the distinct terminology that is used, e-business should not be viewedin isolation from the remaining activities of a firm. Instead, an organization shouldintegrate online e-business activities with its offline business into a coherent whole.The FT article ‘It’s too early for e-business to drop its “e’’’, provides a further discussion of the importance of the ‘e’ in e-business.1.1.2 Electronic commerceElectronic commerce, or e-commerce, is more specific than e-business and can bethought of as a subset of the latter (see Exhibit 1.1). Electronic commerce deals withthe facilitation of transactions and selling of products and services online, i.e. via theInternet or any other telecommunications network. This involves the electronic trading of physical and digital goods, quite often encompassing all the trading steps suchas online marketing, online ordering, e-payment, and, for digital goods, online distribution (i.e. for after-sales support activities). e-Commerce applications with externalorientation are buy-side e-commerce activities with suppliers and sell-side activitieswith customers.4

Chapter 1 · Key terminology and evolution of e-business1.1.3 Mobile e-commerceMobile ‘e-commerce’, or m-commerce, is a subset of electronic commerce. While it refersto online activities similar to those mentioned in the electronic commerce category, theunderlying technology is different since mobile commerce is limited to mobile telecommunication networks, which are accessed through wireless hand-held devices such asmobile phones, hand-held computers and personal digital assistants (PDA).Exhibit 1.1 Electronic business includes electronic commerce and mobileelectronic commercee-businessElectronic commerceMobilee-commerceSource: adapted from D. Chaffey, E-Business and E-Commerce Management, FT Prentice Hall, 2002, p. 9.FTIt’s too early for e-business to drop its ‘e’Jargon is used to make the banal soundenthralling, the simple sophisticated. It is oftenused to disguise the fact that the speaker, orwriter, does not know what he is talking about,or cannot be bothered to find a more preciseword. In the past five years, one letter has cometo symbolize the worst of jargon. The fifth letterin the Roman alphabet, it has been used in frontof business, commerce, finance, procurement,learning, enablement, government. Almost anynoun you can think of has probably been an enoun. Companies have used ‘e’ liberally to givethemselves a buzz on the stock market.Now, ‘e’ is on its way out. Yet, despite everything I have said, this is bad news. The ‘e’ hasbeen chased away by the dotcom crash, whichtransformed it from magic drug to kiss ofstock market death. But, even before that, itwas going out of fashion. One senior consultant told me in 2000 that the ‘e’ would bedropped by his organization within a year ortwo (it was). His argument – widely accepted –was that internet-based business wouldbecome so pervasive that it would be pointless,indeed damaging, to talk about it as a separatediscipline. 5

Part 1 · Introduction 6E-business would and should disappear intobusiness. And so it should; but not yet. At theRichmond Events e-forum last October, severalhundred senior managers from blue-chip companies gathered on a cruise ship to be assaultedby a mixture of cabernet sauvignon and hardsell from vendors of e-services of various sorts.There was a ‘last days of Rome’ feeling about it,as delegate after delegate let slip that he or shehad either just left their e-job, or was about to.What was particularly interesting was thatpeople were revealing their ‘real selves’ beneaththeir e-titles: they were either information technology people, or they were something else. Whilea few could talk strategy and technology withequal fluency, most gave their backgrounds away.They were happy speaking about marketing andstrategy, or about integration issues; not both.I have since received a letter from RichmondEvents announcing the death of e-forum, sayingthat its functions would be rolled into either the ITdirectors or the marketing forum. The divide thatwas apparent at the event has been formalized.Why does this matter? Because, even as it hascrumbled, the value of the letter ‘e’ has becomeever more clear. It is, or has been, a bridgebetween technical and non-technical managers.From the earliest days of the commercialinternet, proponent after proponent of thestrange new medium said the same thing: ‘Don’tlet the IT people run it.’ They believed the effective use of the internet depended not on thetechnology but on a strategic understanding ofwhat it could do.Technologists were, of course, vital for implementing the strategy, but they often knew toomuch about the trees to be able to see the wood.Also, most IT directors had a ‘supplier’ role toan organization; they were rarely involved instrategic decision-making.As the commercial internet becamee-commerce and then e-business this view held,though there were tensions. Many companiesput their trust in new media consultancies ledby marketing people who loved to talk strategy.‘Leave your strategy to us; we understand itbetter than you can,’ they would tell their openwalleted clients. They hired technical people –indeed, the real skills shortage was at the technical end – but they kept control.Sadly, these agencies also sowed the seeds oftheir own destruction, because they could notmatch either the technical skills of systems integration specialists, or the strategic skills of the bigconsultancies. Meanwhile, a sizeable minority oforganizations kept their e-business strategy inhouse and under the control of their ITdepartments. Add to this the rush by boards topour money into Internet ventures simply for thesake of tickling the share price and it is not surprising that so much was wasted so fast by so many.How is it, then, that any companies managedto exploit the new technology effectively? Howdid Cisco, Dell, Electrocomponents, GeneralElectric manage it?Largely, because people at the summit sawthat the secret was in bringing technologists andnon-technologists together and making themwork together – and often they used the banner‘e’ as a marshalling-point. The good e-businessmanagers I have met are (or were) either technologists on the way to becoming strategists, ornon-technologists with an increasing understanding of IT. On the way, I stress; rarely closeto achieving fluency in both.The new media agencies, for all their arrogance, were also attempting to master both skills.Again, they had a long way to go; so it is a shamethat they have been humbled so brutally. Thedanger, as the e-bridge crashes into the river, isthat the great unrealized possibilities of the internet will be swept away with it. When anorganization has a cadre of managers with a realunderstanding of both strategy and technology,fine – let the bridge collapse. But until then, someform of e-business department and function –labeled with whatever jargon – should remainessential to any intelligent group’s structure.Source: D.

Chapter 1 · Key terminology and evolution of e-business1.1.4 The concept of strategyIn addition to e-business, strategy is the second key thrust of this book. More specifically, we analyze and illustrate how firms develop and implement strategies for theire-business activities and draw lessons and guidelines from the studied practices.However, we should recognize that the term ‘strategy’ means different things to different people. To get a clear understanding of the meaning of strategy the way it isused in this book, let us first consider the following definitions of strategy and thensuggest a common foundation.Strategy is: the direction and scope of an organization over the long-term, which achievesadvantage for the organization through its configuration of resources within a changing environment to the needs of markets and fulfill stakeholder expectations.Gerry Johnson and Kevan Scholes2 the determination of the basic long-term goals and objectives of an enterprise, andthe adoption of courses of action and the allocation of resources necessary for carrying out theses goals.Alfred Chandler3 the deliberate search for a plan of action that will develop a business’s competitiveadvantage and compound it.Bruce Henderson.4 the strong focus on profitability not just growth, an ability to define a unique valueproposition, and a willingness to make tough trade-offs in what not to do.Michael Porter5Based on the above definitions, we would like to stress the following aspects that arecrucial for strategy formulation:6 Strategy is concerned with the long-term direction of the firm.Strategy deals with the overall plan for deploying the resources that a firm possesses.Strategy entails the willingness to make trade-offs, to choose between differentdirections and between different ways of deploying resources.Strategy is about achieving unique positioning vis-à-vis competitors.The central goal of strategy is to achieve sustainable competitive advantage overrivals and thereby to ensure lasting profitability.Having defined the concept of strategy, we can now differentiate it from the concept oftactics, a term that is often used interchangeably with strategy. Tactics are schemes forindividual and specific actions that are not necessarily related with one another. In general, specific actions can be planned intuitively because of their limited complexity. Afirm can, for instance, have a certain tactic when it launches a marketing campaign.Strategy, on the other hand, deals with a more overarching formulation that affectsnot just one activity at one point in time but all activities of a firm over an extendedtime horizon. To achieve consistency between different activities over time, intuitionis generally not sufficient; it also requires logical thinking. Drawing an analogy with7

Part 1 · Introductionwarfare, we could say that while tactics are about winning a battle, strategy is concerned primarily with winning the war.Furthermore, it has often been argued that the increasing importance of technologyreduces the need for clear strategies. Firms should instead focus primarily on gettingtheir technology to work. This is especially true for the technology underlyinge-business and electronic commerce. Yet, technology is not, and cannot be, a substitute for strategy. In fact, overlooking strategy and how a firm can create sustainablecompetitive advantage is a likely recipe for failure. Just because certain activities arefeasible from a technological perspective does not mean that they are sensible from astrategic perspective. Ultimately, IT and the Internet should be used not for the sakeof using them but instead to create benefit for customers in a cost-efficient way.Formulating long-term strategies has become more difficult due to the continuously changing business environment. How long-term can a strategy be when thetechnological environment is permanently changing? This is obviously a difficultquestion that has no clear-cut answers to it. When a disruptive innovation emergesand redefines the basis of competition, previous strategies become all but worthless.This was the case, for instance, when Amazon.com entered the book-retailing marketwith its online bookstore and when Napster launched its file-sharing platform foronline music distribution. Nonetheless, it is important to be aware of the trade-offsthat arise when a firm gives up long-term strategy in return for short-term flexibility.Within organizations, we typically recognize the following three different levels ofstrategy (see Exhibit 1.2). They are (1) corporate-level strategy, (2) business unit strategy and (3) operational strategy. It is important to note here that most of the casesfeatured in this book deal primarily with issues related to the first two levels of strategy.Corporate-level strategyThe highest strategy level, i.e., the corporate-level strategy) is concerned with theoverall purpose and scope of the firm. It typically involves the chief executive officer(CEO) and top-level managers. Corporate strategy addresses issues such as how toallocate resources between different business units, mergers, acquisitions, partnerships and alliances.Consider, for instance, the merger in 2000 between AOL and Time Warner, wherethe CEOs of both firms looked across all the businesses of their respective companiesbefore deciding to merge the two corporations. Another example of corporate strategy that is important in the e-business context is the choice of distribution and saleschannels. For example, the top management of Tesco plc first made the decision in1995 about whether to use the Internet to sell groceries online and then on how toset it up organizationally (see Section 9.3 for a discussion of the different ways oforganizing e-commerce ventures). Only then was the responsibility delegated fromthe corporate level to the Tesco.com business unit.Business unit strategyBusiness unit strategy is concerned primarily with how to compete within individualmarkets. Dell, for instance, operates distinct business units that target large corporate8

Chapter 1 · Key terminology and evolution of e-businesscustomers, private households and public-sector customers. Since these are very separate markets, with differing needs and preferences, it is also necessary to formulate adistinct business unit strategy for each one of these markets (see Section 4.1.2 onmarket segmentation for e-commerce).At a more detailed level, a business unit strategy deals with issues such as industryanalysis, market positioning and value creation for customers. Furthermore, whenformulating a business unit strategy, it is also necessary to think about the desiredscale and scope of operations.Operational strategyOperational strategy deals with how to implement the business unit strategy withregards to resources, processes and people. In the context of e-business, this includesissues such as optimal website design, hardware and software requirements, and themanagement of the logistics process. Furthermore, this also includes operationaleffectiveness issues, which are addressed by techniques such as business process reengineering (BPR) and total quality management (TQM).Although these approaches are important, they do not belong intrinsically tostrategy formulation, since, as stated above, strategy is about making trade-offs; thatis, about deciding which activities a firm should perform and which ones it shouldnot perform. Operational issues are of high importance for any organization; however, they are not the primary focus of this book, and covering them in-depth wouldoverextend the scope of the book.8Exhibit 1.2 The focus area of the cases is on corporate level and business unit yOperationalstrategyPrimary focusarea of casesCorporationBusinessunit AFunction ABusinessunit BFunction BBusinessunit CFunction C9

Part 1 · Introduction1.1.5 The concept of value creationThe ability of a firm to create value for its customers is a prerequisite condition forachieving sustainable profitability. In the context of e-business strategies, the conceptof value creation deserves special attention because many Internet start-ups thatended up in bankruptcy at the end of the Internet boom years did not pay enoughattention to this issue. Instead, they were frequently concerned mainly with customeracquisition and revenue growth, which was sustainable only as long as venture capitalists and stock markets were willing to finance these firms.Nowadays, however, in a harder and more turbulent business environment, it isimperative that strategies focus on what value to create and for whom, as well as howto create it and on how to capture the value in form of profits. In economic terms,value created is the difference between the benefit a firm provides to its consumers andthe costs it incurs for doing so. Because of the importance of value creation, we devoteall of Chapter 5 to this topic and address the various issues related to this concept.1.2 The evolution of e-businessBefore discussing e-business from a structural perspective through the e-businessstrategy framework presented in Part 2, we first want to analyze the evolution of ebusiness over the past decade and compare it with the life cycle of other technologicalrevolutions. Carlota Perez defines them as a ‘powerful and highly visible cluster ofnew and dynamic technologies, products and industries, capable of bringing aboutan upheaval in the whole fabric of the economy and of propelling a long-termupsurge of development’. 9Whether the printing press, steam engine, railway or car, all technologies havegone through similar surges. Perez divides the surge of a technological revolutioninto two consecutive periods: (1) the installation period, which consists of an irruption stage and a frenzy (‘gilded age’) stage, and (2) the deployment period, whichconsists of a synergy (‘Golden age’) stage and a maturity stage. These stages are typically separated by a downturn or crash, as shown in Exhibit 1.3.Below, we describe in more detail each stage of a typical surge of a technologicalrevolution:10 10Irruption (1). The irruption stage takes place right after a new technology is introduced to the market. Revolutionary new technologies, also called ‘big bangs’, includethe mechanized cotton industry in the 1770s, the railway construction in the 1830s,and, more recently, Intel’s first micro-processor in 1971. During the irruption stage,innovative products and services based on the new technology appear and start toslowly penetrate the economy, which is still domina

book, such as e-business, electronic commerce and mobile e-commerce, and the concepts of strategy and value cre-ation. It then provides an overview of the evolution of e-business over the past decade and recognizes four distinct periods: (1) the grassroots of e-business, (2) the rise of the
