Show answer & explanationAnswer & explanation
Correct answer: A. Gaining a comprehensive understanding of the new ERP system's architecture, functionalities, and underlying technologies.
Before an IS auditor can effectively assess controls, they must thoroughly understand the system being audited. This foundational knowledge is crucial for identifying relevant risks and designing appropriate audit procedures, especially for a new and complex ERP system.
Why the other options are wrong
- B. Budget allocation for tools is a practical consideration, but understanding the system precedes determining specific tool needs.
- C. While historical data can be useful, it is not the most critical first step for a *new* system where the architecture and controls may differ significantly.
- D. User satisfaction is important for system adoption but less critical for control assessment during planning than understanding the system itself.
