This is an MIT Sloan Management Review article. By strategically outsourcing and emphasizing a company's core competencies, managers can leverage their firms' skills and resources for increased competitiveness. The authors suggest ways to determine what those core competencies are and which activities are better performed externally. They assess the relative costs and risks of "making" or "buying" and present methods for containing risks while enjoying the benefits of their dual approach.

Collaboration in business is no longer confined to conventional two-company alliances, such as joint ventures or marketing accords. Today groups of companies are linking together for a common purpose. Consequently, a new form of competition is spreading across global markets: group vs. group. Call them networks, clusters, constellations, or virtual corporations, these groups consist of companies joined together in a larger overarching relationship. The individual companies in any group differ in size and focus, but they fulfill specific roles within their group. Furthermore, within the network or group, companies may be linked to one another through various kinds of alliances, ranging from the formality of an equity joint venture to the informality of a loose collaboration.

Is your company a rule maker or a rule follower? Does your company focus on catching up or on getting out in front? Do you spend the bulk of your time as a maintenance engineer preserving the status quo or as an architect designing the future? Difficult questions like these go unanswered not because senior managers are lazy--most are working harder than ever--but because they won't admit that they are less than fully in control of their companies' future. In this adaptation from their upcoming book, Hamel and Prahalad urge senior managers to look toward the future and ponder their ability to shape their companies in the years and decades to come. Creating the future, as Electronic Data Systems has done, for example, requires industry foresight. Since change is inevitable, managers must decide whether it will happen in a crisis atmosphere or in a calm and considered manner. Too often, profound thinking about the future occurs only when present success has been eroded.

When companies join forces--whether on research or as full-scale partners--they often tend to emphasize the legal or financial aspects of the deal. But smart managers know that alliances involve much more. Like human relationships, business partnerships are living systems that have endless possibilities. And companies that know how to tap those possibilities and manage alliances effectively have a key corporate asset. Rosabeth Moss Kanter calls it a collaborative advantage. After completing a study of more than 37 companies from 11 parts of the world, Kanter concludes that relationships between companies grow or fail much like relationships between people. By paying attention to the human aspects of alliances, managers can leverage the maximum value from them, Kanter believes. Examples of companies enjoying a collaborative advantage today are FCB and Publicis; Northern Telecom and Matra Hachette; and the European Retail Alliances partners, Ahold, Argyll, and Groupe Casino.

Health care reform in the United States is on a collision course with economic reality. Most proposals focus on measures that will produce one-time cost savings by eliminating waste and inefficiency. But the right question to ask is how to achieve dramatic and sustained cost reductions over time. What will it take to foster entirely new approaches to disease prevention and treatment, whole new ways to deliver services, and more cost-effective facilities? The answer lies in the powerful lessons business has learned over the past two decades about the imperatives of competition. In industry after industry, the underlying dynamic is the same: competition compels companies to deliver constantly increasing value to customers.

Describes the three business segments of PepsiCo (beverages, snack foods, and restaurants). It then explores the competitive environment within each segment and the response of PepsiCo's businesses. It seeks to show how PepsiCo CEO, D. Wayne Calloway, in a very "hands-off" and decentralized manner, achieves high growth rates in each segment through a process of "continual transformation." Calloway strives to hold together a fast-growing and rapidly changing business through shared values (instead of implementing tighter controls and increasing supervision).

Updates the Disposable Diaper Industry in 1974. Intended as an in-class handout.

Describes, in the words of its cofounder, the history of EnClean, an industrial and environmental services company, from its origins in 1984. The company grew rapidly and diversified into new businesses and new geographies both through acquisition and internally. It went public in 1989 but then suffered major losses in 1992 and 1993. The founder must now decide how to respond to a secret board ultimatum.

Emphasizes the connection between a firm's activities and its prices, costs, and volumes. A firm obtains a competitive advantage when it adopts a system of interrelated activities that generate superior profitabiltiy. Briefly describes differentiation and low-cost strategies.

The competition between Coke and Pepsi is a classic corporate battle that began in America at the turn of the century and has expanded into worldwide competitive warfare in the 1990s. This case examines the economics of the soft drink and bottling industries, and describes the history and internationalization of the cola wars.

Describes the history and diversification strategy of the Japanese manufacturer Asahi Glass Co. The company has diversified through internal growth, acquisition, and joint ventures from its origin in flat glass to a broad glass-materials, chemical, and electronics manufacturer. It has also vertically integrated and expanded internally to become the leading global glass manufacturer. In 1993, Asahi Glass is reviewing its future direction, particularly whether it should divest its electronics business.

Officials at United Technologies Corp. (UTC) must decide on an ethics policy to govern competitive intelligence gathering. The flow of competitor information into the Pratt & Whitney division has declined sharply since adoption of UTC's code of ethics. A rewritten version of an earlier case.

Newell is a $1.5 billion manufacturer and distributor of low-tech home and hardware products, geared to serve volume purchasers. In 1992, Newell is considering two approaches to expand its current product line with the acquisitions of Sanford Corp., a $140 million manufacturer and marketer of writing instruments and office supplies, and Levolor, a $180 million manufacturer of window blinds. The case focuses on Newell's enduring corporate strategy as a guide for selecting appropriate acquisitions to grow the company.

The early 1990s saw a new wave of start-ups in the U.S. airline business. One entrant, Kiwi International Air Lines, took to the skies in September 1992 with a strategy of attracting small-business travelers looking to save money but lacking the flexibility to book in advance. Fares were to be pegged to the lowest restricted fares in the market, but offered on an unrestricted basis. Another setting in which entrants have recently sought to capture market share from large, established players is the U.S. credit card industry. In the early 1990s, the industry witnessed an onslaught of new players wooing customers with offers of low interest rates and small or nonexistent fees. This case explores some aspects of the game between small-scale entrants and large-scale incumbents.

The case 'Wal-Mart Stores, Inc.' focuses on the evolution of Wal-Mart's remarkably successful discount operations and describes the company's more recent attempts to diversify into other businesses. The company has entered the warehouse club industry with its Sam's Clubs and the grocery business with its Supercenters, a combination supermarket and discount store. Wal-Mart experienced a drop in the value of its stock price in early 1993, which it still has not made up. Wal-Mart has advantages over its competitors in areas such as distribution, information technology, and merchandising, to name a few.

In 1992 PepsiCo is considering two opportunities to expand its restaurant business, Carts of Colorado, a $7 million manufacturer and merchandiser of mobile food carts, and California Pizza Kitchen, a $60 million chain in the casual dining segment. The discussion focuses on whether PepsiCo should pursue these opportunities, and if so, how the relationships might be structured, given PepsiCo's large organization and decentralized management structure. Examines strategy formulation and coordination issues in a related set of businesses that are part of a large, decentralized consumer products company.

Costly "wars of attrition" are common. Examples include: 1) the battle over the business of market-making in British government bonds that took place following the 1986 deregulation of the London financial markets, and 2) the battle that took place in the late 1980s between British Satellite Broadcasting and Sky Television over the U.K. satellite broadcasting business. The case explores what can happen when two companies find themselves engaged in a war of attrition. Analysis shows that given any length of time whatsoever, it is possible to rationalize a strategy of fighting for precisely that length of time. This provides a reason why wars of attrition often lead to long fights and large cumulative losses for the players involved. There is an irreducible "fog of war" that makes the war of attrition a very dangerous game to play.

Virtually all manufacturers aspire to "world-class" status. But even those who attain it will only be as good as their toughest competitors. This explains why so many companies that have adopted improvement programs like just-in-time, lean production, and total quality management lament that they never seem to get ahead. The problem is that managers tend to view such programs as solutions to specific problems, like high inventories or products that are difficult to manufacture. As such, they are not manufacturing strategies. In the turbulent 1990s, the goal of competitive strategy should be strategic flexibility. A company must be able to switch gears relatively quickly and with minimal resources. A true manufacturing strategy is a plan for developing the skills and capabilities that will enable a company to do certain things better than competitors over the long haul.
