The UN Office on Drugs & Crime has produced this guide, which says that a corruption risk assessment is a systematic tool that can be used by public organisations to identify corruption vulnerabilities within their operations and devise efficient, cost-effective strategies to mitigate those vulnerabilities or risks. The goal of any risk assessment is to identify a realistic set of potential areas or scenarios that may be vulnerable to corruption, determine which should be prioritized, and develop and implement mitigation measures. It provides a long list of corruption-related irregularities.
