An internal auditor plans to conduct a walk-through to evaluate the control design of a process. Which of the following techniques is the auditor most likely to use?
When an internal auditor conducts a walk-through to evaluate the control design of a process, the techniques most likely to be used are inquiry and observation. These techniques allow the auditor to understand how the process is designed and how controls are implemented and followed in practice.
IIA Standard 2320 – Analysis and Evaluation:
This standard requires internal auditors to analyze and evaluate the information gathered during the engagement to ensure that it is sufficient, relevant, and reliable. During a walk-through, inquiry and observation are key techniques for gathering this information.
Inquiry:
Inquiry involves asking questions of personnel involved in the process to understand the control design, its purpose, and how it is intended to work. This helps the auditor gain insight into the process and identify any potential gaps or weaknesses in control design.
Observation:
Observation allows the auditor to see the process in action. By watching how the process is carried out, the auditor can verify whether the controls are being applied as designed and whether they are effective in practice.
IIA Practice Advisory 2320-1:
The advisory supports the use of inquiry and observation as primary techniques for understanding and evaluating the design and operation of controls during a walk-through.
Option A (Observation and inspection): While useful, inspection is more about examining documents or physical evidence rather than understanding process design.
Option C (Inspection and reperformance): Reperformance involves independently executing a control, which is more relevant for testing control effectiveness rather than evaluating design.
Option D (Inquiry and reperformance): Reperformance is not typically used in a walk-through focused on control design evaluation.
Detailed Explanation:Why Not Other Options?Conclusion: Option B is correct because inquiry and observation are the most appropriate techniques for conducting a walk-through to evaluate the design of a control, as they provide direct insight into how the process and controls are intended to work, in line with IIA standards.
