Performance-based metrics (also known as consequence-based metrics) are generally quantitative approaches for answering the question, “How resilient is my system?” These metrics interpret quantitative data that describe infrastructure performance during disruptive events. The required data can be collected from historical events, subject matter estimates, and computational infrastructure models. These metrics are suitable for benefit-cost and planning analyses because they measure the potential benefits and costs associated with proposed resilience improvements and investments. Resilience metrics need to include a measure of consequences and the relevant statistical probability from the probability distribution of those consequences.
