Predictive Analytics is more interested in getting the events of the future rather than of the past or the present. The accuracy of the Predictive Analytics greatly depends on the accuracy and usability of the data and also on the level of analysis and the quality of assumptions.
At a more granular level the Predictive Analytics can be thought as something that is related with creating predictive scores for an individual organizational element. The domain of Predictive Analytics is different from forecasting in the sense that the in Predictive Analytics there is learning from the data in order to predict the future so organizations can make better decisions.
Today’s businesses need to go beyond knowing what has happened to giving the right assessment of what will happen in the future. Though Predictive Analytics has been there for quite some time now it is only recently that it has got some serious clout thanks to the following reasons:
- The availability of faster, cheaper computing systems
- Software that is use to deploy and maintain
- The need for a real competitive edge
Due to these developments that we are seeing it is clear that Predictive Analytics has not just remained the sole domain of mathematicians and statisticians but has been more wide-spread.
