Risk Inventory is a “fourth” dimension of risk that provides insight into embedded elements of risk that are not specifically covered by a Key Risk Indicator. Subtle risks are inventoried in this way so that they can be studied orthographically. What does that mean? Orthographic representations of risk are from made from the front view (Subjects), the top view (Silos), the end view (COSO), and, from the inside out ( which is ‘Risk Inventory’). Examples of risk inventory are Product Development Risk, Customer Relations Risk, Training & Backup Risk and Denial of Service Risk.
