Concurrent session 4.1 - WRAPS - How to make better decisions 

Inspired by the New York Times bestselling authors’ book “DECISIVE: How to make better decisions” (Heath and Heath, 2013), I will apply the WRAPS model to the world of internal auditing. While internal auditors are not the decision maker for what the implementation of remediating actions is concerned, nonetheless, they are taking many decisions regarding their processes and outcomes. Along the acronym WRAPS, I will share my perspective on how to improve such decisions when seeking to render effective internal audit services. Thereby, I will focus, among other aspects, on the challenges of “narrow framing” (“Widen Your Options” is recommended) and “overconfidence” (“Prepare to be Wrong” is recommended).

My perspective benefits from over 25 years of international experience in global organizations as finance and audit executive and my dive into the world of academia in parallel to my full-time job, performing empirical research about internal audit, too.
