Introduction
Today, business organizations are constantly bombarded by many different constellations of change, including challenges and risks in the environment (Sarens and De Beelde, 2006). As organizations operate to carry out their mission, they are exposed to threats and opportunities that can either bolster their growth or bring about their demise. How an organization deals with change and understands its capacity to address the change is a critical factor for its survival. While there are many factors that could impact the organization, this study focuses on the burgeoning role and changing responsibility of the Internal Audit Function (IAF) as a behavioral response to the environmental change factor of regulation. Therefore, when major changes in regulations occur, pressures can cause organizations to adjust their structures, processes and strategies (Haveman et al., 2001). This study addresses the following research question, “How does the environmental change factor of regulation bring about a shift in the Internal Audit Function’s Role in the organization post-SOX?”
