The Hidden Cost of Untested Assumptions
Every strategic decision rests on assumptions. Some are explicit: market projections, competitor behaviour, resource availability. Most are invisible: cultural norms, unspoken expectations, "how things work here."
When decisions span borders, cultures, and stakeholder groups, these invisible assumptions multiply. And they're where the most expensive failures hide.
The Pattern of Failure
After 20+ years working across medical, diplomatic, governmental, and corporate environments, I've seen the same pattern repeatedly:
1. Confidence Without Verification
Leadership teams reach consensus quickly. The decision feels right. Everyone agrees. But agreement isn't validation. The assumptions underlying the decision were never stress-tested.
2. Cultural Blind Spots
What works in one context fails spectacularly in another. Not because the strategy was wrong, but because it assumed a cultural reality that didn't exist.
3. Stakeholder Misalignment
Different stakeholders operate from different assumptions. Without surfacing these, alignment is an illusion that shatters under pressure.
4. The Sunk Cost Spiral
Once committed, organisations double down rather than question. The original assumptions become sacred, even as evidence mounts against them.
Why Traditional Approaches Fall Short
Most strategic planning processes are designed to build consensus, not challenge it. They reward confidence, not questioning. They produce beautiful slide decks that obscure the assumptions buried within them.
Even "devil's advocate" exercises often fail. The advocate is performing a role, not genuinely stress-testing. The outcome is predetermined: the decision moves forward with a veneer of rigour.
What's Actually Required
Genuine decision rigour requires:
Structured methodology - not ad hoc questioning, but a systematic approach to surfacing and challenging assumptions.
External perspective - someone without organisational politics or career stakes in the outcome.
Cross-cultural competence - understanding how assumptions vary across contexts.
Psychological safety - creating space where challenge is welcomed, not punished.
