CORE DEFINITION

To improve system reliability, deliberately add duplicate components or information. Although it reduces efficiency (increases cost), it improves resilience.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Antifragile structure: not just data backup. In communication, important things are said three times (information redundancy); in supply chain, there must be alternative suppliers (resource redundancy). Do not cut all redundancy for extreme efficiency.

anchor

Anchor fast decisions

Adding duplicate components/information/channels to the system so that a single point of failure does not cause overall failure. Trade efficiency/cost for reliability and resilience, conforming to an 'antifragile' structure.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Identify critical single points in the system
Add backups for critical points (components/suppliers/information duplication)
Weigh redundancy level against cost
Regularly drill switching to ensure effectiveness.
