Choosing the walkthrough technique for evaluating an organization's manual log review process is particularly effective because it allows the auditor to gain a comprehensive understanding of the process in a step-by-step manner. By conducting a walkthrough, the auditor can engage with personnel involved in the log review, observe their actions, and ask questions to clarify uncertainties. This hands-on approach provides valuable insights into how logs are reviewed, the controls in place, and any potential weaknesses in the process.

Walkthroughs can uncover issues related to adherence to procedures, understanding of roles, and identification of any deviations from expected practices. This technique not only assists in assessing compliance with established protocols but also facilitates direct communication with staff, enabling auditors to collect qualitative data that might not be evident through other methods like sampling or observation.

Other techniques, while useful in different contexts, may not provide the same level of detail about the manual log review process. For example, sampling could overlook critical log entries, reperformance may be impractical due to the resource-intensive nature of manually executing the process, and observation may not capture the rationale behind decision-making in the log review process. Therefore, the walkthrough method is optimal for gaining a thorough understanding of the manual log review process and assessing its effectiveness.
