Computer Assisted Auditing Techniques
Computer Assisted Auditing Techniques (CAATs) are techniques developed to audit electronic data, to audit things that cannot be audited manually or to make the audit more rationally. It is approved by GAAP.
Techniques
These techniques include, but are not limited to:
- Fraud testing (SAS 99)
- Random sampling (with physical verification)
- Curve data deviation
- Average or median user data input calculation and prediction
- Age analysis
- Gap analysis
- Duplicate analysis
- Data stratification
There are commercial companies that have developed Generalized Audit Software, where some of these techniques are available, and artificial intelligence algorithms, which are applied to data to assist in the human auditing.
