Systematic improvement from experience. Convert outcomes into better future performance.
Learning is not automatic. Experience without reflection is just repetition. Learning requires deliberate extraction of insight and updating of beliefs and behaviors.
| Single-loop | Did action work? | Corrected action | Gap between expected/actual | | Double-loop | Is frame right? | Updated frame | Pattern of single-loop failures | | Reflection | What can we learn? | Transferable insights | Experience completed | | Experimentation | Should we test this? | Validated/invalidated belief | Belief needs validation |
Extracts insights and improves performance from experience. Applies single-loop (fix action), double-loop (fix frame), reflection (extract insight), experimentation (test belief), and calibration (adjust confidence) modes. Use when correcting mistakes, learning from outcomes, testing hypotheses, or improving predictions. Triggers on "why did this fail", "what can we learn", "test this", "how accurate are we", "pattern of failures". Source: bellabe/lean-os.
