An interesting article which explores the "external factors" that IoT projects face.  Rarely does one size really fit all - integration is a necessary evil to get really specific business value from systems or processes. Meanwhile, companies like Hitachi have been using their own sensor data within their processes for decades of years. The growth in cost effective sensors within, and increasingly outside the enterprise brings an additional complexity to the challenge, with some interesting variants on the usual data issues around security, the 3 Vs, transmission and timing issues to mention just a few.

Taking a more external perspective to taming these age old issues will help in the quest for securing the real value IoT brings.
