Toyota Katashiki Code Guide

| Layer | Focus | Visual Cue | Anomaly Signal | |-------|-------|------------|----------------| | Physical Katashiki | Parts & tools | Consistent orientation, shadow boards, cassette angles | A bolt lying sideways; a torque wrench out of silhouette | | Process Katashiki | Movement & time | Rhythm of hand passes; gap between worker A and B | A pause > 0.8 sec; a worker stepping outside baseline path | | Sensory Katashiki | Sound & vibration | Hum of conveyor; click of pneumatic driver | Absence of expected click; a higher-pitched vibration |
