Cascading risk / cascading fragility / cascade failure

When failure in one part of a connected system triggers a chain of failures across the whole system.

Details

Our Take
Three closely related terms. The key distinction: cascading risk is the probability framing; cascade failure is what happens when it goes wrong; cascading fragility names the built-in weakness that makes cascades possible. In preparedness conversations, the fragility framing is often more useful because it points to what can be changed before the trigger event.
