The 27th International “What if?” Workshop has brought data farming experts together at the National Defence University in Helsinki, Finland. Data farming is a way to conduct operational analysis through modeling and simulation, high performance computing to build scenarios, and then explore new options for decision makers. The methodology permits planners and decision makers to ask the “what if?” questions to determine the probabilities of various outcomes. The workshop is being attended by representatives from Germany, Sweden, Canada, Turkey, the U.S. and Finland.
