Foresight Scenario Method
Also known as: Scenario planning, Intuitive-logics scenarios, Scenario building
The scenario method constructs a small set of internally consistent, plausible stories about how the future might unfold, built from the key driving forces and critical uncertainties facing a decision. Rather than forecasting one expected future, it deliberately develops several contrasting futures so that strategies can be tested against a range of possibilities and decision-makers can rehearse responses to what might otherwise be surprises.
Key highlights
- Handles deep, irreducible uncertainty by exploring multiple plausible futures instead of committing to a single fragile forecast.
- Challenges entrenched assumptions and broadens mental models, helping organisations avoid being blindsided by surprises.
- Produces robustness testing—strategies can be evaluated against several contrasting worlds rather than one expected case.
- Generates vivid, communicable narratives that engage stakeholders and build shared understanding far better than abstract projections.

When to use it
Use the scenario method when key uncertainties are too large or irreducible for point forecasting, when a strategy must be robust across several possible futures, and when broadening stakeholders' thinking and challenging their assumptions is itself a goal. It is well suited to long horizons, contested or turbulent environments, and foresight exercises that need a structured way to explore alternatives. The method assumes that the future is genuinely open, that a handful of critical uncertainties can frame a useful range of futures, and that qualitative, narrative reasoning adds value alongside quantitative analysis. It is less appropriate when uncertainty is low and a single reliable forecast suffices, when decisions are short-term and operational, or when there is no appetite to confront uncomfortable alternative futures.
Strengths & limitations
- Handles deep, irreducible uncertainty by exploring multiple plausible futures instead of committing to a single fragile forecast.
- Challenges entrenched assumptions and broadens mental models, helping organisations avoid being blindsided by surprises.
- Produces robustness testing—strategies can be evaluated against several contrasting worlds rather than one expected case.
- Generates vivid, communicable narratives that engage stakeholders and build shared understanding far better than abstract projections.
- Quality depends on the skill and breadth of participants; poorly chosen uncertainties or unimaginative teams yield bland, similar scenarios.
- The qualitative, narrative output resists quantification and can be hard to integrate with formal models or to evaluate objectively.
- Reducing the future to two axes and a few scenarios inevitably omits possibilities and can create a false sense of completeness.
- Scenario exercises are resource-intensive and their influence on actual decisions is often weak unless deliberately embedded in strategy.

Frequently asked
How many scenarios should a study produce?
Most practitioners build three to four scenarios. Two often collapse into a simplistic best-case/worst-case framing, while more than five become unwieldy and hard for stakeholders to hold in mind. The common two-by-two matrix—built from the two most important critical uncertainties—naturally yields four contrasting futures, which is widely regarded as a practical and cognitively manageable number.
Are scenarios assigned probabilities?
In the dominant intuitive-logics tradition, scenarios are deliberately not assigned probabilities; each is treated as plausible and equally worth considering, precisely to avoid anchoring on a 'most likely' future and dismissing the others. Some schools, notably the French 'la prospective' and certain quantitative variants, do attach probabilities or use cross-impact analysis, but doing so risks the false precision the method is meant to avoid.
How does the scenario method fit within foresight?
Scenario building is one of the most widely used techniques inside broader technology-foresight exercises. Horizon scanning supplies the emerging issues and driving forces; scenarios then weave selected uncertainties into coherent alternative futures; and the resulting worlds inform priority-setting, roadmaps, and policy. Scenarios are often combined with Delphi surveys to elicit and validate the driving forces and with roadmapping to translate a preferred future into action.
