Artículo 13. Performing Walkthroughs

.37 As discussed in paragraph .20, the auditor may perform walkthroughs as part of obtaining an understanding of internal control over financial reporting. For example, the auditor may perform walkthroughs in connection with understanding the flow of transactions in the information system relevant to financial reporting, evaluating the design of controls relevant to the audit, and determining whether those controls have been implemented. In performing a walkthrough, the auditor follows a transaction from origination through the company's processes, including information systems, until it is reflected in the company's financial records, using the same documents and IT that company personnel use. Walkthrough procedures usually include a combination of inquiry, observation, inspection of relevant documentation, and re-performance of controls. Note: For integrated audits, AS 2201 establishes certain objectives that the auditor should achieve to further understand likely sources of potential misstatements and as part of selecting the controls to test. AS 2201 states that performing walkthroughs will frequently be the most effective way of achieving those objectives. 20 .38 In performing a walkthrough, at the points at which important processing procedures occur, the auditor questions the company's personnel about their understanding of what is required by the company's prescribed procedures and controls. These probing questions, combined with the other walkthrough procedures, allow the auditor to gain a sufficient understanding of the process and to be able to identify important points at which a necessary control is missing or not designed effectively. Additionally, probing questions that go beyond a narrow focus on the single transaction used as the basis for the walkthrough allow the auditor to gain an understanding of the different types of significant transactions handled by the process.
