This document discusses scenario thinking and scenario planning. Scenario thinking can be used for setting strategic direction, catalyzing bold action, accelerating collaborative learning, and alignment and visioning. Basic principles of scenario thinking include re-perception, understanding that the status quo is not an option, understanding and managing uncertainty, taking a long view, and using outside-in thinking and multiple perspectives. For scenarios to be useful and credible they must be relevant, coherent, plausible, important, and transparent. Scenario planning involves systems analysis, retrospective analysis, analyzing actors' strategies, scenario drafting, identifying key issues and forces, determining driving forces, selecting scenario logics or rationales, fleshing out scenarios, and considering implications.
