CORE DEFINITION

From Greek mythology, Achilles was an invulnerable warrior, but he died from an arrow to his heel (the only part not dipped in the River Styx). It is a metaphor for the weakest, most vulnerable fatal flaw in an apparently powerful system.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Risk audit. When designing any system, pay special attention to potential single points of failure. True robustness is not overall strength, but the absence of obvious weaknesses.

Anchor fast decisions

From Homer's epic, the hero Achilles was invulnerable except for his heel, which was his only fatal weakness, illustrating a fatal shortcoming within overall strength.
