This session introduces Scenario Planning, which is a technique that has been successfully used by Shell and the Global Business Network for forty years. It is based on identifying the external events that can drive change in the system under study; determining ranges over which those drivers could reasonably be expected to change in the time frame under study; and evaluating the system effects of multiple interacting changes in these drivers. The end result is a small number, ideally less than ten, scenarios or possible future pathways. Each of these is given a title that is evocative of its significant features, and the participants then develop plans for responding to these scenarios. Ideally, the participants will leave this session with a set of conceptual plans for recognizing and responding to trigger events that lead to these different alternative futures in such a way as to optimize community goals and harmonize them with goals articulated in the Future Search.
