Case study scenario

Illustrative scenario: reducing false positives in transaction monitoring

A hypothetical description of prioritising alerts for investigators. No client or result is implied.

This is an illustrative scenario created to show how an approach would work. It does not describe a real client engagement or real results.

The scenario

A financial institution operates rule-based monitoring that generates many alerts, most of which are closed as benign. Investigators spend much of their time on low-value cases.

The approach

We would retain the existing rules, which have regulatory standing, and add a prioritisation model that scores alerts using customer, transaction and historical-outcome features. The score would reorder queues rather than suppress alerts, keeping compliance accountability unchanged.

Governance

The model would be documented to model-risk standards, validated independently and monitored for drift. Reason codes would be shown to investigators.

Note

This is a hypothetical scenario for explanation. It is not an account of work performed for any institution.
