What is the purpose of walk-throughs in auditing?

The purpose of walk-throughs in auditing is to observe controls operating in practice. This methodology involves tracing a transaction from its initiation through to its completion in order to understand the process and identify any potential control weaknesses. By directly observing how controls function in real-time, auditors can assess the effectiveness of those controls and determine whether they are being adhered to within the organization. This hands-on approach provides more reliable and comprehensive insights compared to merely relying on theoretical documentation or interviews about the controls.

While the other options mention aspects of auditing that could seem relevant, they do not capture the essence of what walk-throughs aim to achieve. For instance, while inquiry is an important part of gathering information, it does not provide the same level of assurance as direct observation does. Similarly, evaluating the accuracy of interview statements is a valuable audit task, but it is not the primary goal of conducting a walk-through. Lastly, reducing dependency on external verification is a broader concept that doesn't specifically relate to the purpose and intent of walk-throughs in the audit process. The walkthroughs focus on firsthand observation of processes, thus validating the design and operational effectiveness of internal controls.
