"At their core, platforms enable a plug-and-play business model. Other businesses can easily connect their business with the platform, build products and services on top of it, and co-create value. Platforms primarily benefit not from internal production but from a wider source of open co-creation and open market interactions. This ability to drive interactions through a plug-and-play infrastructure is a defining characteristic of platform scale." (p. 33)
