Risk-based review.

An Excel analytics add-in combining financial-ratio analysis, Benford’s Law screening and pattern-based grouping to detect anomalies, support risk-based review and help target investigation.
across two investigation bureaus.
Behind the work
The challenge
Recurring investigation tasks required repeated financial calculations and manual review of large datasets.
My contribution

In practice

A better next question.
