Idea in Brief

The Sea Change

Platform businesses that bring together producers and consumers, as Uber and Airbnb do, are gobbling up market share and transforming competition. Traditional businesses that fail to create platforms and to learn the new rules of strategy will struggle.

The New Rules

With a platform, the critical asset is the community and the resources of its members. The focus of strategy shifts from controlling to orchestrating resources, from optimizing internal processes to facilitating external interactions, and from increasing customer value to maximizing ecosystem value.

The Upshot

In this new world, competition can emerge from seemingly unrelated industries or from within the platform itself. Firms must make smart choices about whom to let onto platforms and what they’re allowed to do there, and must track new metrics designed to monitor and boost platform interactions.

Back in 2007 the five major mobile-phone manufacturers—Nokia, Samsung, Motorola, Sony Ericsson, and LG—collectively controlled 90% of the industry’s global profits. That year, Apple’s iPhone burst onto the scene and began gobbling up market share.
