DATA ANALYTICS — FRAUD DETECTION METHODOLOGY NOTE

Entity: ___ · Period analysed: ___

This note documents the analytical techniques applied to the population(s) of transactions examined, and why each was selected. It records methodology and its rationale; the specific instances and amounts identified through each technique are documented separately in the working papers/findings log for this engagement — this note is not, itself, the findings record. Where this engagement also involves standard SA 240 journal entry testing, see the existing `journal-entry-testing-working-paper` template, which carries its own Benford leading-digit table for that specific procedure; use this note where the analytics go beyond that standard battery.

Common questions

FAQs.

How is this different from the Benford table in the journal entry testing working paper?
The journal-entry-testing-working-paper's Benford table is part of the standard SA 240 procedure applied in every audit. This note is for an investigation-specific engagement where the analytics go further or are documented as a standalone methodology record — for example combining Benford analysis with duplicate-payment and threshold-avoidance testing across a broader dataset than routine JE testing covers.
Why document methodology separately from the results?
Separating the two makes the methodology independently reviewable and reproducible — a reviewer, opposing expert, or tribunal can assess whether the technique was appropriate and correctly applied without wading through the specific transactions found, and the same methodology record can be referenced across multiple findings without duplicating the description each time.
Can a Benford deviation alone be reported as evidence of fraud?
No — it should be reported as a screening result that warranted further investigation, along with what that further investigation found (or didn't find). Presenting a statistical deviation on its own, without the underlying transaction-level examination, overstates what the technique actually proves and is a common, avoidable weakness in fraud analytics reporting.
