Concept and origins
Scenario planning is a strategy method for highly uncertain environments that systematically imagines what could happen instead of trying to guess what will happen. The military strategist Herman Kahn developed it at RAND, and Pierre Wack of Royal Dutch Shell brought it into corporate strategy in the 1970s. Having examined an oil-price-shock scenario in advance, Shell is credited with responding to the 1973 oil crisis faster than its rivals (Wack, 1985).
Steps
- Set the focal question: define the decision and time horizon (for example, the market in ten years).
- Identify driving forces: gather social, technological, economic, environmental and political (STEEP) drivers.
- Separate predetermined elements from uncertainties: distinguish near-certain trends such as demographics from high-impact factors whose direction is unknown.
- Build the scenario framework: use two high-impact, highly uncertain factors as axes of a 2x2 matrix to define four futures.
- Write the stories: name each scenario and narrate it as a causal story.
- Draw strategic implications: find strategies robust across all scenarios and signposts (leading indicators) for each.
How it differs from forecasting
Traditional forecasting assumes one most-likely future; scenario planning assigns no probabilities and treats several futures on an equal footing. Schoemaker (1995) argued that it counters two common decision errors, overconfidence and tunnel vision.
Limitations
- It takes considerable time and participant effort.
- Choosing the wrong axes can miss important futures.
- It fails if scenarios are mistaken for forecasts or are not tied to real decisions.
Related methods
It is used alongside the Delphi method for expert input, SWOT analysis for internal and external factors, and Porter's five forces for industry structure, and helps entrepreneurs assess uncertain opportunities.
