ISACA Certified Information Systems Auditor (CISA) ExamDomain 3: Information Systems Acquisition, Development and ImplementationMedium
An IS auditor is reviewing the system acquisition process for a new cloud-based human resources (HR) management system. The organization plans to integrate this new system with its existing payroll and enterprise resource planning (ERP) systems. Which of the following should the auditor primarily focus on to ensure successful integration and data flow?
- AEvaluating the system's API documentation and data mapping specifications.
- BAssessing the training plan for HR personnel on the new system.
- CAnalyzing the contractual terms for service level agreements (SLAs).
- DReviewing the vendor's financial stability and support model.
Show answer & explanationAnswer & explanation
Correct answer: A. Evaluating the system's API documentation and data mapping specifications.
Successful integration relies heavily on well-defined interfaces and data structures. Reviewing API documentation and data mapping ensures that the new system can communicate and exchange data accurately with existing systems.
Why the other options are wrong
- B. User training is vital for system adoption but is a post-integration activity and does not directly ensure technical integration success.
- C. SLAs define performance expectations and remedies but do not detail the technical mechanisms for system integration.
- D. Vendor financial stability is important for business continuity but does not directly address technical integration challenges.
System Integration Focus
Ensuring different information systems can communicate, exchange data, and operate together seamlessly.
- Requires well-defined interfaces and data formats.
- Critical for avoiding data silos and manual reconciliation.
- Involves technical standards, protocols, and data mapping.
Memory trick: To link systems, look at the documentation, not just the decoration.
