To apply CA, there are certain audit tools that must be installed within the information system of the auditee. The auditor can use what is called computer-assisted audit tools and techniques (CAATs). CAATs can be defined as “computer assisted tools that permit the auditor to use the computer to gather or assist in gathering audit evidence” (Zhao et al., 2004). Examples of CAATs are embedded audit modules (EAMs), exception reporting, transaction tagging, parallel simulation, test data or integrated test facilities, generalized audit software and continuous and intermittent simulation.
