Abstract

This research investigates the nuanced relationship between internal audit maturity and enterprise risk management effectiveness through a novel methodological framework that combines computational social science with organizational network analysis. Unlike previous studies that primarily employed survey-based approaches, this study introduces a multi-dimensional audit maturity index derived from natural language processing of audit documentation and risk management artifacts across 47 multinational corporations. Our methodology represents a significant departure from conventional approaches by quantifying audit maturity through computational analysis of audit trail data, communication patterns, and decision-making processes. The findings reveal a non-linear relationship where audit maturity demonstrates diminishing returns beyond certain thresholds, challenging the conventional wisdom that continuous audit function enhancement invariably improves risk management outcomes. Specifically, we identify three distinct phases of the maturity-effectiveness relationship: an initial rapid improvement phase, an optimization plateau, and a potential regression phase where excessive audit sophistication may inadvertently create organizational complexity that undermines risk management agility. The study contributes original insights by demonstrating that the most effective risk management occurs not at maximum audit maturity, but at an optimal balance point that varies by organizational context. These findings have profound implications for how organizations should strategically invest in audit function development and provide a new theoretical framework for understanding the complex interplay between control mechanisms and risk management effectiveness in modern enterprises.
