concerns, then the number of countries to be monitored and stress-tested regularly over the next decade may rise to between 50 and 60. Stress testing should also be applied periodically to global systems that meet critical needs, including food supply systems, global public health systems, supply chains for critical materials, and disaster relief systems.
Decision science techniques should be used and further developed to ensure that the stress tests make the best use of the available information. Stress testing might draw on various methods, including the qualitative interpretation of available knowledge, formal modeling, and interactive gaming approaches. Decision science techniques should be employed to design the processes and interpret the input from different kinds of expertise and modes of analysis in order to make the best possible use of information. The stress-testing exercises should themselves be monitored and critically evaluated so that stress-testing methods can be improved over time.
