Computer-Assisted Audit Techniques
Parallel simulation – actual company data are processed using auditor – controlled software program. Does not contaminate data.
Test data – dummy transactions are prepared by the auditor and processed under auditor control by the client’s computer program. Simple, quick, and inexpensive.
Integrated test facility – creates a small subsystem within the regular IT system. Can create errors in clients files.
Continuous monitoring of online real time systems – use test data to test controls. Contamination can occur.
Tagging Transactions – place indicators or tags on selected transactions and trace through the system.
