SMED, when every changeover is seen
A vision of how this could look — illustrative, not a deployed system.
What does SMED become when every changeover is observed, continuously, with no stopwatch?
A camera classifies every action internal/external across hundreds of runs, surfacing the pattern no sample could. The engineer stops timing and starts deciding.
The camera sees that a wait repeats; only the operator knows why. Judgment and trust to change it stay human.
Changeover time recovered turns straight into capacity on a line that changes format all day.
