This is an interesting way to summarize the main building elements of enterprise IoT:

One thing that is implied in this diagram through phrases such as “connected workplace,” “business process monitoring, control, & optimization,” etc., is that humans are still heavily involved in the process. 

I feel this is just a temporary need as IoT will continue to move towards its complete automation.  Computer algorithms will then take care of the most predictable parts of control and decision-making, and humans will continue to deal with less-certain, subjective, or the most risky decisions.
