COMPONENTS OF AUDIT INFORMATION TECHNOLOGY DEPLOYMENT IN LISTED DEPOSIT MONEY BANKS IN NIGERIA

Abstract

This study examined the components of Audit Information Technology (AIT) deployment in listed Deposit Money Banks (DMBs) in Nigeria, using Principal Component Analysis (PCA) to identify key factors that explain variations in technological adoption across institutions. The analysis utilized five major variables: Audit Information Technology (AIT), Software Acquisition Cost (SAC), Operating Cost (OPC), Human Resource Cost (HRC), and Firm Size (FSZ). The PCA results revealed that the first three components accounted for approximately 75.5% of the total variance, indicating a strong explanatory power of the extracted factors. Specifically, Component 1 (29.96%) was heavily loaded on AIT and OPC, suggesting that digital infrastructure and operational compliance form the core of audit technology deployment. Component 2 (25.74%) was strongly associated with SAC and HRC, highlighting the role of system control and staff competence in ensuring audit efficiency. Component 3 (19.80%), dominated by FSZ, implied that larger banks tend to have greater capacity for technology adoption. The findings demonstrate that variations in audit technology deployment among DMBs are primarily influenced by differences in technological infrastructure, staff expertise, and organizational capacity. The study concludes that enhancing human capital and system controls can significantly strengthen the deployment of audit technologies, thereby improving audit quality and financial transparency in Nigeria’s banking sector.
