The badge on the dog reads HOT. It is the team you are trying to build. The one where the truth reaches you in time, while it is still cheap to fix.
The trap
Telling people to be braver does nothing. For each person, staying quiet is the safe bet. So they take it.
The move
Toyota did not ask workers to be braver. They made pulling the cord rewarded, not punished. The cost of silence changed for everyone at once.
What ZMT does
The founder signs in public. Silence starts to cost something. Speaking gets documented protection. The manifesto holds the why, the operating principles hold the how, the daily log makes it visible. Grey turns gold.
