Internal Audit Standards and Practice Guides

In a mature control environment with limited internal audit resources, internal auditors should focus their testing on preventive key controls. Preventive controls are designed to stop errors or irregularities before they occur, making them crucial for maintaining control effectiveness. Key controls are the most important controls in mitigating risks to an acceptable level. By focusing on these, internal auditors can ensure that the most critical risks are managed effectively despite limited resources. References:

To gather relevant feedback on the newly implemented software used by 3,000 employees in South America and Europe, distributing surveys to the software users in both regions is the best approach. Surveys can reach a large number of users quickly and can provide comprehensive feedback on various aspects of the software, including usability, functionality, and user satisfaction. This method allows for the collection of a wide range of opinions and experiences, which can be analyzed to identify common issues and areas for improvement.

Benchmarking in internal auditing involves comparing the performance or practices of the audited entity against a standard or best practice, which often involves using information from other organizations or sources as a reference. This process helps identify areas for improvement and set performance targets. Thus, comparing the collected information with similar information from another source is the correct definition of benchmarking.
