Statistical models that find patterns
Descriptive (good)What happened
Predictive (better)What will happen
Prescriptive (best)What action will produce the best outcome

Data Challenges - accessible, usable
Resource Challenges - people, tools, time
Cultural Challenges - information is valuable,algorithms are useful
… but can be difficult to implement
