Improved intelligence sharing after 9/11 is helping Homeland Security
authorities identify credible terrorist attack threats more effectively.
progress highlights urgent needs for tools to help leaders formulate
validate plans to prevent and respond effectively to terrorist attack.
Spreadsheets and other simulation tools lack the horsepower to address
these decision problems. They excel at manipulating numeric data and
regular trends, but security threats revolve around uncertain and rapidly
changing information, disruptive events and shifting terrorist goals and
strategies. Disaster exercises are valuable learning tools, but they are
difficult and costly to conduct, so they are staged infrequently.
