Scenario Analysis¶

Why It Matters¶

Single-point predictions are routinely wrong, yet organizations demand "the answer." Scenario analysis acknowledges irreducible uncertainty while still providing actionable insight. It identifies which factors matter most, reveals decision robustness across futures, and prevents surprise when the unexpected (but previously considered) occurs.

The Key Move¶

Identify 2-3 key uncertainties that will shape outcomes (not all uncertainties - focus on high-impact, genuinely uncertain factors). Construct 3-4 scenarios that combine these uncertainties in different ways. Each scenario must be: internally consistent (the logic holds), plausible (not just possible), distinct (they diverge meaningfully), and decision-relevant (they imply different actions). For each scenario, develop the narrative: what happens, what are leading indicators, what should you do differently?

Classic Application¶

Shell's energy scenarios in the 1970s. Rather than predicting oil prices, Shell developed scenarios around different geopolitical futures. One scenario involved OPEC supply disruption - considered unlikely by most. When the 1973 oil crisis occurred, Shell was prepared because they'd already gamed that scenario, giving them competitive advantage while others scrambled.

Surprising Application¶

Career planning. Rather than trying to predict the job market, develop scenarios: "AI disrupts my industry," "My industry grows but becomes more competitive," "Industry declines but adjacent opportunities emerge." For each, identify skills you'd need, relationships to build, and financial reserves required. This makes you robust to multiple futures rather than optimized for one prediction.

Failure Modes¶

Developing scenarios that differ only in magnitude (optimistic/pessimistic versions of the same story rather than structurally different futures). Secretly believing one scenario is "the real one" (defeats the purpose). Making scenarios too extreme to be plausible (sci-fi rather than genuine uncertainty). Not connecting scenarios to decisions (they should inform action, not just map possibilities). Developing scenarios but not monitoring for which is unfolding (need leading indicators).
