"Value Quadrants maps value creation and revenue model changes by asking WHEN and WHERE is value being created. The WHEN of value creation is function of the handset lifecycle, from design, development and production (pre-sales phase) to point-of-sale and in-life use (post-sales phase). There WHERE of value creation is either on the device (hardware, software, patents and industrial design) or on the services ‘cloud’ (for designing and delivering content and services)" - Vlado Handziski
