From a clear economic point of view Business Productivity is simple: human resource is simply too expensive and too risky. So Business Productivity software solutions make to increase the speed of carrying out a task or increase the general availability of a human resource. Examples are efficient collaboration and project systems, offline and home office availability, automated business processes and so on.
However if we stay with the economic point of view: the cheaper and more effective solution is to fully replace the human resource with artificial intelligence software. In this sense in Business Productivity, the major question is not how a certain activity can be delivered with more efficient Business Productivity software solutions, but the question is if a certain activity still needs humans or is it possible to replace fully with artificial intelligence.
It may sound shocking for the first sight, however the same thing has been being happened with the human physical labor in the last hundred years: everything that could be automated were automated.
Welcome to the second machine age.
