The Five Competitive Forces That Shape Strategy

Abstract

This article includes a one-page preview that quickly summarizes the key ideas and provides an overview of how the concepts work in practice along with suggestions for further reading. 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.

PayPal: The Next Chapter

Can a social purpose and stakeholder capitalism confer a powerful competitive advantage in the age of COVID-19? For PayPal, the answer is yes. After spinning off from eBay in a 2015 IPO, the company declared its purpose as "democratizing financial services" by ensuring that low-income consumers and small businesses can efficiently and inexpensively manage their money. The company fully lives into this purpose, sending employees out into communities to experience firsthand the indignities and high fees imposed on the unbanked, dramatically lowering the cost of international remittances, enabling small businesses to access working capital without credit checks, and facilitating cross-border purchases for small merchants. The company takes the welfare of each stakeholder group seriously: achieving racial and gender pay equity, raising hourly worker pay and benefits to ensure a living wage, and building a diverse and inclusive culture; working closely with regulators and law enforcement to unearth signs of sex trafficking and terrorism; aggressively removing hate-group transactions; providing $4 billion in credit to hundreds of thousands of small businesses that would never have qualified for bank loans, especially those owned by women and people of color. Together these actions have built a high degree of trust that creates a competitive moat in the otherwise commodity business of online payments. During the pandemic, the company was able to get stimulus funds to individuals and small businesses far faster and less expensively than banks or the SBA, and committed $500 million to investments in black-owned businesses. In the 5 years since its IPO, despite intense competition from major banks and credit card companies, Google, Apple, and countless VC-backed fintech players, the company has more than doubled its users, increased profits and boosted the stock price 500%.

As the diffusion of value-based health care efforts accelerates globally, the need for interoperable information technology systems that support value-based care is essential. Such systems are needed to facilitate dramatic improvements in patient outcomes and efficiency and, importantly, to end an era in which health IT has entrenched the status quo, perpetuated silos, and blocked reimbursement reform. A value-enabling IT platform must organize data around conditions and must enable integrated practice units to integrate care both within and across health systems. In addition, the electronic health record should be the sole source of costing information so that accurate costs for every encounter can be tracked, aggregated, shared, and used for improvement. This is the next generation of health care IT.

Since its establishment in 2005, Hamburg’s Martini Klinik had single mindedly focused on prostate cancer care with a commitment to measure long-term health outcomes for every patient. A wholly owned subsidiary of the University Hospital Hamburg, Martini Klinik was a “hospital in a hospital” in close proximity to other medical departments and services. By 2019, Martini Klinik had become the largest prostate cancer treatment program in the world with 8,000 outpatient cases and more than 2,500 surgical cases annually. Patients came from all over Germany and from around the world. A new and expanded facility was under construction to have the capacity to manage more patients with prostate cancer.
