Operational risk is defined as “the risk of loss resulting from inadequate or failed internal processes, people and systems, or from external events.” Financial markets in the last two decades have been highlighted by large-scale financial failures due to incompetence and fraud, such as Barings, Daiwa, Allied Irish Banks, Orange County, Enron, along with man-made and natural disasters, such as “9/11,” Hurricanes Andrew and Katrina.

Risk mapping is often mentioned both in describing various approaches to operational risk management and, in an audit context, in formulating the key steps to control self-assessment, as the cornerstone of the risk identification process. Yet there is little published guidance on how to perform it effectively and on how to ensure that the resulting map is indeed complete and consistent. In other words, although the term is widely used by bankers, auditors, regulators and consultants alike, and although all these professionals
may even agree on what constitutes an acceptable final product, they will most likely give widely different explanations on how to get such product,
