Harvard Business Review is a leading business magazine with a long history. A new book in the Harvard Business Review: Top 10 Articles series brings together the most helpful content from HBR experts on platforms and ecosystems. Digital platforms and ecosystems—networks that connect service and product providers with millions of consumers within a single infrastructure—are pushing traditional businesses out of the market. Platforms are growing in popularity as they allow users to reduce transaction costs and quickly access services and technology solutions. The authors of this collection tell you how to navigate the changing technology landscape and get the most out of the platform economy. You will learn how to develop a business model for your own platform and keep your company competitive on someone else's, why some platforms fail miserably while others take over the market, what is the power of network effects and how to develop a two-pronged strategy.
