To immediately enhance and maintain long-term IT audit quality, inviting qualified staff from the IT department to serve as guest auditors is a viable solution. This approach provides immediate access to IT expertise, ensuring high-quality audits. Additionally, it fosters collaboration between the IT and internal audit departments, promotes knowledge transfer, and helps build internal audit staff capabilities over time. This method is both cost-effective and sustainable, compared to contracting external specialists continuously.
