The Golden Chain

The golden chain is a way of thinking about how each part of a system works together, like a chain. Imagine a chain with lots of links. Each link in the chain represents a part of the system, and the links all fit together. Every link in the chain needs to work properly in order for the system to work well. If one link is missing or broken, the system won't work. The golden chain means that all the links need to work together in order to make the system work.
