When most people hear “feedback,” they cringe — picturing a tense annual review. But in systems theory, feedback is far simpler: route the output back as an input. It is how a cell knows to stop dividing. Without feedback loops, systems drift into chaos (entropy).
Modern management moved from command and control (linear orders) to sense and respond (circular loops). Agile, Lean, OKRs — the underlying mechanic is identical: act, measure, adjust.
How to read this: the red line is why yearly reviews and 5-year plans fail — problems compound invisibly. The green line is capped risk: small wrongs, caught early, fixed cheap.
The only way to survive in a complex environment is to learn faster than the environment changes.
