CHAPTER 4 Results Summary Following the application of countermeasures to the high-consequence assets, the user may assemble a summary report by asset class or in total of all asset classes. The report will list the relevant risks, threshold selections, number of critical assets, expenditure by countermeasure class, and summary totals of resources required by countermeasure category. This summary can be saved to a hard drive, or printed for reference. The results summaries provide a snapshot of multimodal risk, consequence thresholds, and chosen measures to mitigate the exceeding of those thresholds. This snapshot can be compared to later iterations of CAPTA as the user makes different choices of threshold or selects different assets to be included. Part II portrays examples of the results summary. The results summary is the most visual and iterative aspect of the process. The user can re-enter the model to choose different thresholds that alter the results. Alterations may occur due to increased tolerance for adverse impacts or changes in the levels of allocated resources. 35
