INTRODUCTION

CORE DEFINITION

Ju an si wei says that while you are in a safe environment, you should be thinking about the danger that could arise. Its model is black swan defense, and its timing claim is counterintuitive: the moment with the most cash on the books is the best moment to run the change and the stress test. Do not wait for the rain to start before fixing the roof.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Spend the fat on the fix: use the flush period to fund the change you have been deferring. - Run the worst case: do the disaster rehearsal while conditions are still calm. - Hold the buffer: keep cash, redundancy, and contingency as an asset, not a leftover.

Anchor fast decisions

Buffers are built during good times and consumed during bad ones, so the work of preparation can only be paid for before it is needed. Stress testing in calm conditions finds the break while it is still cheap to discover, and the rehearsal is a form of storage: the response is built before the pressure that would otherwise prevent building it.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Run the worst-case scenario and the stress test while things are going well. 2. Build the cash, redundancy, and contingency buffer before it is needed. 3. Review the fragility points on a fixed cadence rather than after shocks. 4. Fund the deferred change from the flush period, not from the crisis.
