Build error correction mechanisms into systems from the
Build error correction mechanisms into systems from the start rather than treating errors as anomalies to be prevented through discipline.
Why This Is a Principle
This principle derives from Catastrophic failures in complex systems rarely result from (alignment of failures produces catastrophes) and Every system is perfectly designed to get the results it (systems produce the results they're designed for). It prescribes building correction mechanisms upfront rather than assuming perfection. The lesson's examples of DNA repair, Shannon's error correction codes, and Toyota's production systems all demonstrate this as a design choice, not just descriptive observation.
