Scenario building helps to show possible consequences of strategy implementation. Scenario building designs a hypothetical situation so that strategic planners can assess the consequences and implications of using specific strategic actions without the risk and possible negative consequences being implemented in the real world. It is essentially modeling the effects of a single change, something often done in the world of science and is just as applicable to business. There are software programs that can help with modeling scenarios, although simply working them out on paper using the combined knowledge of a team can be equally valuable.
