This document discusses scenario planning as a strategic tool for businesses to prepare for an uncertain future. Scenario planning involves identifying key driving forces that could impact a business, such as political, economic, social and technological factors. Managers then develop plausible scenarios or stories about how these factors could interact and influence the future environment. This allows businesses to assess different strategic options and make robust decisions that will work under a variety of potential futures. The document provides examples of companies that have successfully used scenario planning, such as Royal Dutch Shell. It also outlines the steps involved in scenario planning, from identifying uncertainties to developing four plausible scenarios to guide strategic decision making.
