What is QRA?

QRA most likely refers to Quantitative Risk Assessment. It is a process used to numerically analyze the probability and impact of risks. It often involves using statistical methods, modeling, and simulations to assign numerical values to the likelihood of various adverse events and the potential losses or damages they could cause. QRAs are used in various fields such as finance, project management, and engineering to make informed decisions about risk mitigation and management.
