This document provides guidance on developing scenario plots for strategic planning. It discusses two approaches for identifying a small number of scenario logics or plots from the virtually infinite number of possible futures: the inductive approach and deductive approach. The inductive approach involves brainstorming emblematic events or deviations from an "official future" until consensus is reached. The deductive approach prioritizes the key factors of uncertainty and uses a 2x2 matrix based on the two most important uncertainties. Once the scenario logics are identified, the next step is to flesh them out into compelling narrative stories.
