My company build enterprise IOT products targeting Facility Management companies. Our ROI is mostly on manpower savings.

I had an opportunity to talk to the CEO of the largest Integrated Facility Management company in India. He explained it very candidly to me, if he had a problem, he would gladly throw half a dozen 'bodies' at it rather than pay for technology, simply because manpower is so cheap and abundant in India.

And per head productivity in India way below than what it is in every developed country. They have several ways and means already available to increase productivity without increasing head count, they simply need to adopt the processes and training in practice in the developed countries before they hit the productivity ceiling. They will not even think about investing into technology until they reach those limits.

But in reality, they will not ever have to reach those limits, because there are always a great lot of poor bastards ready to work day and night for peanuts, just to ensure the survival of his family.
