The inaugural IoT business index is based on a survey of 779 executives from around the world, conducted by The Economist Intelligence Unit in June 2013. Survey respondents were asked to indicate the extent to which their companies currently make use of the IoT in their external products and services, and separately in their internal operations and processes (see Research Methodology for a full explanation).
The index is on a scale of 1 to 10. The scale represents five “stages” of IoT use: the highest or most advanced stage (a score of 9 or 10) equates to extensive use of the IoT, whereas the lowest stage (a score of 1 or 2) equates to non-existent (or virtually non-existent) use of the IoT. A score that lies between these stages indicates that businesses are transitioning from one stage to another."
