A common risk management taxonomy is a set of terms and definitions that are used consistently across the enterprise to describe, measure, and report on risks. A common risk management taxonomy is essential for integrating IT risk with the ERM framework, as it enables a common understanding of risk concepts, categories, and levels among different stakeholders and functions. A common risk management taxonomy also facilitates the aggregation and comparison of risks across the enterprise, and supports the alignment of risk appetite and tolerance with business objectives12.
