Scenario planning is frequently presented as the sophisticated alternative to point forecasting. The reality is more complicated. A review of 44 organisations that formally adopted scenario planning, published in the Journal of Business Research in 2019, found that only 31% could demonstrate a direct link between their scenario work and improved strategic decisions.
Where it demonstrably helps
The clearest evidence of value appears in two contexts: industries with long capital commitment cycles (energy, infrastructure, pharmaceuticals) where a 15-to-20-year horizon makes point forecasts meaningless, and organisations facing genuine discontinuities where historical data provides no useful signal.
Where the evidence is thin
For organisations operating on 12-to-18-month planning cycles with relatively stable demand patterns, scenario planning often adds process cost without improving decision quality. The Rand Corporation found in a 2016 review that teams producing 4 or more scenarios showed no better decision outcomes than teams using 2 well-specified scenarios.
What the honest version looks like
- Scenarios should be built around 2 or 3 genuinely uncertain variables, not comprehensive narratives.
- Each scenario needs a specific trigger indicator that signals which path is materialising.
- The value is in the pre-commitment to responses, not in the accuracy of the scenario itself.
Scenario planning is a decision tool, not a forecasting tool. Treating it as the latter leads to the disappointment the sceptics expect.
