Performing a risk assessment is deemed the most critical step when planning an IS audit because it establishes the foundation for the entire audit process. A thorough risk assessment allows auditors to identify potential areas of vulnerability and prioritize them based on their impact and likelihood. This prioritization helps focus resources and attention on the most significant risks, ensuring that the audit addresses the most pressing issues within the information systems.

By understanding the risks associated with the systems being audited, auditors can tailor their approach, including the allocation of time and resources, to areas that pose the greatest threat to the organization. This proactive approach not only enhances the effectiveness of the audit but also aligns the audit objectives with the overall risk management strategy of the organization.

While identifying stakeholders, developing an audit timeline, and gathering historical data are all important components of the audit planning process, they serve as supporting elements to the risk assessment. Without a clear understanding of the risks, the effectiveness of the audit may be compromised, as it could overlook critical vulnerabilities that need to be addressed.
