Predictive Analytics has come a long way in last few years. It continues to get simplified and the consensus is that you no don't need a PH.D. to practice it. It is no longer a backroom activity and modern tools are allowing it to be deployed to much larger population in an organization. You also don't need to wait for your data warehouse to be in place before you can start predictive analytics. The tools continue to make it much easier to visualize and explain the results.
In general, the field is evolving at a rapid pace. Still most of the organizations, with few exceptions, don't have a strategy and roadmap in place. More awareness is required to understand use cases and best practices. Yes, there are more predictive analytics books on this topic which again validates the popularity of this discipline. But a conference like Predictive Analytics conference is a good place to start where there is a great opportunity to network and understand how others are benefiting from this discipline.
