Understanding the fraud triangle concept
Launch library · evergreen read

The fraud triangle is a simple framework describing three conditions that tend to appear together when fraud actually occurs: pressure, such as a personal financial difficulty; opportunity, meaning a genuine gap in oversight that makes the act possible; and rationalisation, the internal justification a person constructs to make the act feel acceptable.
The framework's usefulness lies less in predicting who will commit fraud and more in identifying where an organisation's own controls are weakest. Reducing opportunity, through separation of duties and regular reconciliation, is usually the easiest of the three elements for an organisation to directly influence and control.
Rationalisation is the least visible element but often the most revealing in hindsight, since people who commit fraud frequently convince themselves the organisation somehow owes them, or that the act is only temporary and will be corrected later. Recognising this pattern helps investigators understand motive without excusing the underlying conduct itself.
