Data

And Analytics Means What Exactly?

1. OptimisationOptimal decisions under competing

constraints.

2. Understanding connectivityConnectivity between attributes leading to

a decision ie “market basket analysis”; orunderstanding clustering of outcomes.

3. Predicting the futurePredicting future outcomes based upon

history.

A rapidly changing landscape

Analytics = $++

It’s not just the licensing…

…it’s the infrastructure.

So go cloud, but take care…

How is this useful?

Classic bank examples are• Risk analysis

– Market risk– Credit risk– Operational risk
