This document discusses predictive analytics as a product and some of the challenges involved. It notes that predictive analytics has become more complex due to demands like monetization opportunities, integration of multiple data sources, and the need for solutions to work across initiatives. Modular, shareable, and monetizable approaches are needed, such as standards like PMML and PFA that allow models to be deployed and scored in different systems. The scaling demands also require platforms that can build solutions once and use them everywhere via application programming interfaces (APIs).

- 7. Intended for Knowledge Sharing only Intended for Knowledge Sharing only SOME CHALLENGES 7 Unrealistic expectations on RoI. Operates in siloes, not complemented by user research/other internal or external data/experimentation results. Field testing & iterative development still predominantly offline. Deployment, Post Deployment management & monitoring expensive. Not easy to turn on/off, tweak, flip, scale. Predictions driven significantly by historical trends and relationships. Expectations modeled as simulations.
