Platform architecture is essentially network-centric. it involves coordination of modules (or sub-components) designed and delivered by different independent entities. So, while we may credit Apple for shifting the music industry to the network era, its success equally well depends on the broader ecosystem that it has orchestrated. Microsoft–despite succeeding in architecting the Wintel platform–has been unable to win with Zune thus far. Similarly, GM OnStar is a relatively closed (GM-centric) telematics platform that has not yet been adopted by any non-GM automakers for it to be considered a network-centric strategy while Microsoft is initially partnering with Ford Motor Company to launch a new dashboard OS. When Microsoft extends this experiment to deliver this functionality to non-Ford cars, it becomes a platform architect in the same spirit of Windows and Office platforms.
Platform architects earn revenue in two ways. There is direct payment from the users of the platform (e.g., Windows Vista or Office 2007, Sony PS3 or Xbox) or indirect payment from other parties involved in business transactions (e.g., advertising in the case of Google or transaction fee in the case of Visa or Amazon or eBay). The choice depends on network characteristics and customer propensity to pay for different features under different conditions.
