Stress Testing

Systematically subjecting a system, plan, or strategy to extreme conditions to identify failure points before they occur in reality. Unlike probability-based risk assessment (which asks 'how likely is failure?'), stress testing asks 'how does the system behave under extreme conditions?'—regardless of probability. Financial stress tests simulate economic crashes; engineering stress tests push materials to breaking point; strategic stress tests ask 'what if our biggest customer left, our key employee quit, or our market halved?' The goal is finding fragility before reality finds it for you.

When to use it

Before committing to major strategies or investments; when evaluating business plans or financial projections; when designing systems that need to survive adverse conditions; when existing risk assessments feel insufficient because they only address typical scenarios.

How it can help

For any important plan or system, identify the key assumptions and stress them to extremes. Revenue projections: what if sales are 50% below forecast? Team: what if two key people leave simultaneously? Market: what if a well-funded competitor enters? Supply chain: what if your primary supplier fails? The stress test passes not when everything goes perfectly but when the system survives the stress without catastrophic failure. If the stress test reveals catastrophic failure modes, redesign for resilience before proceeding.
