A key element in coputer-assisted audit techniques is

Definition of Computer-Assisted Audit Techniques (CAATs):

CAATs use software tools to perform audit tasks such as data analysis, testing transactions, and evaluating internal controls.

Obtaining accurate and relevant data is a key first step, as it forms the basis of any analysis performed using CAATs.

Explanation of Answer Choices:

A. Writing the system audit program: This is part of audit planning but not a specific feature of CAATs.

B. Verifying internal controls: While CAATs can be used to test controls, obtaining data is fundamental to this process.

C. Obtaining appropriate data: Correct. CAATs rely on accurate, relevant, and complete data for meaningful analysis.

D. Purchasing data mining software: While software is a tool for CAATs, the focus is on using data, not on acquiring the software itself.
