In 1979, a young associate professor at Harvard Business School published his first article for HBR, "How Competitive Forces Shape Strategy." In the years that followed, Michael Porter's explication of the five forces that determine the long-run profitability of any industry has shaped a generation of academic research and business practice. In this article, Porter undertakes a thorough reaffirmation and extension of his classic work of strategy formulation, which includes substantial new sections showing how to put the five forces analysis into practice. The five forces govern the profit structure of an industry by determining how the economic value it creates is apportioned. That value may be drained away through the rivalry among existing competitors, of course, but it can also be bargained away through the power of suppliers or the power of customers or be constrained by the threat of new entrants or the threat of substitutes. Strategy can be viewed as building defenses against the competitive forces or as finding a position in an industry where the forces are weaker. Changes in the strength of the forces signal changes in the competitive landscape critical to ongoing strategy formulation. In exploring the implications of the five forces framework, Porter explains why a fast-growing industry is not always a profitable one, how eliminating today's competitors through mergers and acquisitions can reduce an industry's profit potential, how government policies play a role by changing the relative strength of the forces, and how to use the forces to understand complements. He then shows how a company can influence the key forces in its industry to create a more favorable structure for itself or to expand the pie altogether. The five forces reveal why industry profitability is what it is. Only by understanding them can a company incorporate industry conditions into strategy.

Describes the economic development of Indonesia from independence after World War II to 2006 and the post-Suharto period. The coverage of the post-Suharto period provides evidence of how political and economic conditions are intertwined after a change in the political regime. Profiles the business environment in 2006, including a documentation of past and present policies that shaped the current situation. A particular focus is Indonesia's stance towards attracting foreign direct investment (FDI). The country has a checkered history of oscillating between seeking and fighting foreign investors.

Describes the economic development of Iceland since 1945, focusing in particular on the years since 2000, when Iceland experienced strong growth and Icelandic companies aggressively internationalized.

Over the 1980s and 1990s, America's changing health care payer environment resulted in mergers of numerous community hospitals into hospital systems. Based in Appleton, Wisconsin, ThedaCare stood out among community hospital systems in its pursuit of service rationalization, clinical quality improvement, and value-based delivery. Driven by determined leadership, ThedaCare began site-based service line rationalization and introduced innovative care delivery models. ThedaCare is a metaphor for the challenges of transforming American community hospital systems. Can be used to teach: the evolution of structure, organization, and strategy of U.S.-based community hospital systems; integrated practice units and care cycles; management of health care quality improvement processes; challenges in diffusion of care delivery innovation; and cost transparency and quality measurement.

Climate change will affect everything businesses do, as government efforts to mitigate carbon emissions cause their prices to rise steeply. This special edition of Forethought takes a hard-nosed look at the risks and opportunities of climate change. Michael E. Porter and Forest L. Reinhardt argue that the effects of climate change on companies' operations are now so tangible and certain that the issue is best addressed with the tools of the strategist, not the philanthropist. Reinhardt also posits, in another article, that success in a carbon-constrained world will be determined by innovation and acumen, requiring companies to make bold moves. Peter Schwartz explains that firms that do business in vulnerable regions can advance their interests if they help those areas adapt to global warming. Daniel C. Esty notes increasing pressure on corporations to reduce emissions, predicting that companies that fail to do so will face grave consequences. Andrew J. Hoffman says that corporations need to know what regulatory issues are at stake--and where. Alyson Slater of Global Reporting Initiative discusses the challenges and benefits of voluntary disclosure. Auden Schendler cautions companies buying up renewable energy certificates that they could end up tarnishing their green credentials. Theodore Roosevelt IV and John Llewellyn explain that virtually any firm in any sector can reap the benefits of investors' surging demand for green business ideas. Vicki Bakhshi and Alexis Krajeski show how climate change will affect businesses in the midterm. Maria Emilia Correa describes a key plank of the strategy at Masisa, a company in Chile, that is engaging B2B customers in efforts to become greener. Mark Way and Britta Rendlen explain why insurer Swiss Re is persuading employees to reduce their carbon footprints. HBR also provides a forecast of the extreme climate phenomena likely to occur in the future, and their expected repercussions on industry, agriculture, and settlements.

Describes the joint efforts of the German health plan KKH and Essen University Hospital to develop an integrated practice unit (IPU), and the West German Headache Center's efforts to improve the quality of migraine care. Provides an overview of the German health care system detailing its provider, health plan, and reimbursement structure. Following new legislation in 2004, which allowed health plans and selected providers to contract outside of the regular group purchasing scheme, KKH and Dr. Deiner of Essen University Hospital developed a novel delivery structure for migraine care. Challenges and hurdles to implementation are described for both the health plan and the IPU. Provides detailed data to allow students to evaluate success, identify current challenges, and recommend improvements to the integrated care system.

Describes the economic development of Latvia, a small eastern European country on the shores of the Baltic Sea, from regaining independence in 1991 to European Union (EU) accession in 2004 and is set on May 1st, 2004, the day Latvia became an EU member. Latvia had achieved strong growth since regaining independence from the Soviet Union in 1990. Describes Latvia's economic development over this period, discussing the economic policy efforts that have taken place and includes general information on the country, its history and politics, and the business environment that companies faced in 2004. A special focus is the influence that the EU accession process has on the Latvian economy and on economic policy choices in the country. Challenges students to discuss how the environment changes as EU membership is achieved, and which new priorities the country might need to define for its economic policy.

Examines the structural determinants of industry attractiveness (the Five Forces framework) and the implications of industry structure for strategy.

Governments, activists, and the media have become adept at holding companies to account for the social consequences of their actions. In response, corporate social responsibility (CSR) has emerged as an inescapable priority for business leaders in every country. Frequently, though, CSR efforts are counterproductive, for two reasons. First, they pit business against society, when in reality the two are interdependent. Second, they pressure companies to think of corporate social responsibility in generic ways instead of in the way most appropriate to their individual strategies. The fact is, the prevailing approaches to CSR are so disconnected from strategy as to obscure many great opportunities for companies to benefit society. What a terrible waste. If corporations were to analyze their opportunities for social responsibility using the same frameworks that guide their core business choices, they would discover, as Whole Foods Market, Toyota, and Volvo have done, that CSR can be much more than a cost, a constraint, or a charitable deed--it can be a potent source of innovation and competitive advantage. In this article, Michael Porter and Mark Kramer propose a fundamentally new way to look at the relationship between business and society that does not treat corporate growth and social welfare as a zero-sum game. They introduce a framework that individual companies can use to identify the social consequences of their actions; to discover opportunities to benefit society and themselves by strengthening the competitive context in which they operate; to determine which CSR initiatives they should address; and to find the most effective ways of doing so. Perceiving social responsibility as an opportunity rather than as damage control or a PR campaign requires dramatically different thinking--a mind-set, the authors warn, that will become increasingly important to competitive success.

As a newly minted CEO, you may think you finally have the power to set strategy, the authority to make things happen, and full access to the finer points of your business. But if you expect the job to be as simple as that, you're in for an awakening. Even though you bear full responsibility for your company's well-being, you are a few steps removed from many of the factors that drive results. You have more power than anybody else in the corporation, but you need to use it with extreme caution. In their workshops for new CEOs, held at Harvard Business School in Boston, the authors have discovered that nothing-not even running a large business within the company-fully prepares a person to be the chief executive. The seven most common surprises are: You can't run the company. Giving orders is very costly. It is hard to know what is really going on. You are always sending a message. You are not the boss. Pleasing shareholders is not the goal. You are still only human. These surprises carry some important and subtle lessons. First, you must learn to manage organizational context rather than focus on daily operations. Second, you must recognize that your position does not confer the right to lead, nor does it guarantee the loyalty of the organization. Finally, you must remember that you are subject to a host of limitations, even though others might treat you as omnipotent. How well and how quickly you understand, accept, and confront the seven surprises will have a lot to do with your success or failure as a CEO.

The U.S. health care system is in bad shape. Medical services are restricted or rationed, many patients receive poor care, and high rates of preventable medical error persist. There are wide and inexplicable differences in costs and quality among providers and across geographic areas. In well-functioning, competitive markets, such outcomes would be inconceivable. In health care, these results are intolerable. Competition in health care needs to change, say the authors. It currently operates at the wrong level. Payers, health plans, providers, physicians, and others in the system wrangle over the wrong things, in the wrong locations, and at the wrong times. System participants divide value instead of creating it. (And in some instances, they destroy it.) They shift costs onto one another, restrict access to care, stifle innovation, and hoard information--all without truly benefiting patients. This form of zero-sum competition must be replaced by competition at the level of preventing, diagnosing, and treating individual conditions and diseases. Among the authors' well-researched recommendations for reform: Standardized information about individual diseases and treatments should be collected and disseminated widely so patients can make informed choices about their care. Payers, providers, and health plans should establish transparent billing and pricing mechanisms to reduce cost shifting, confusion, pricing discrimination, and other inefficiencies in the system. And health care providers should be experts in certain conditions and treatments rather than try to be all things to all people. U.S. employers can also play a big role in reform by changing how they manage their health benefits.

Atlas must decide whether to acquire La Indeca, increasing its Central American presence, or to focus on larger Latin American markets where higher growth is possible. In the year 2000, Jorge Rodriguez was in charge of Atlas Electrica, the largest home appliance firm in Central America. Although it had almost doubled its sales in the 1990s, by the end of the decade Atlas was experiencing a declining market share in its home region and facing increasing competition from outside the region, especially from Mexican and Korean multinationals. At the time, Atlas' main competitor in Central America, El Salvador-based Indeca, was up for sale. Atlas Electrica, based in Costa Rica, served more than a dozen Latin American countries. Since its establishment in 1961, it had served Central American markets with different types of home appliances, later focusing on white-goods for middle-income segments of Central American consumers. In the mid-1990s, through a strategic alliance with Sweden's AG Electrolux, Atlas had expanded to Latin American markets beyond Central America.

Supplements The California Wine Cluster.

Le Centre Suisse d'Electronique et de Microtechnique S.A. (CSEM)--the Swiss Center for Electronics and Microtechnology--was a major nonprofit research institution located in Neuchatel, Switzerland, with roots in the Swiss watch industry. CSEM maintained close links to several Swiss universities, and over time, the center's activities expanded to include basic and applied research, contract production, and technology consulting. By the late 1990s, CSEM began spinning off promising commercial ventures and incorporating them as for-profit companies. In 2001, CEO Thomas Hinderling wondered whether any adjustments in CSEM's strategy were necessary or desirable going forward.

Describes the evolution of AFP Provida, one of the early entrants into the Chilean pension fund system established in 1981. By 1999, AFP Provida was not only the largest pension fund administrator in Chile, but also the largest in Latin America in terms of number of affiliates and the second largest in terms of assets under management, after the Brazilian company Previ. Provida was also the most international firm in the industry. At the turn of the 20th century, Provida's senior management was considering how to extend the company's position in a rapidly expanding international marketplace. Describes the firm's internationalization process in terms of timing, geographic choices, and modes of entry. Also discusses Chilean special conditions for the pension fund industry, including local factors, context for strategy and rivalry, demand conditions, and related and supporting industries. Allows for the discussion of the origins of clusters in developing economies as well as the sources of international competitive advantage. Also provides an interesting evaluation of Provida's strategic choices and the sustainability of its international leadership.
