What is risk analysis?

• A. Quantifying the likelihood and magnitude of an undesirable outcome.
• B. Predicting the exact outcome.
• C. Ignoring uncertainty.
• D. Reducing costs without modeling uncertainty.

Answer: (A)

Risk analysis focuses on uncertainty by estimating both how likely an undesirable event is and how severe its impact could be. It uses probabilistic models to represent inputs, runs simulations or analyzes scenarios, and communicates results as distributions or risk metrics rather than a single fixed value. This approach helps you compare options, identify where mitigation matters most, and decide where to allocate resources. For example, you might assign probabilities to cost overruns and estimate their potential size to understand overall risk exposure. The idea of predicting a single exact outcome, ignoring uncertainty, or trying to cut costs without reflecting risk misses the essential purpose of risk analysis, which is to quantify and manage the effects of uncertainty.
