A team learns what matters by watching which mistakes leaders remember longest.

Stated values are learned from posters; real ones are learned from memory. People watch which errors get mentioned a year later and which are forgotten by Friday, and they adjust accordingly, avoiding whatever category of failure seems to leave a mark. Nobody announces this system, and it is far more powerful than any written set of priorities.

Notice which mistakes you are still bringing up, and ask whether that matches what you claim to care about. Let something go out loud if it has been carried too long. What you stop mentioning teaches as much as what you keep.
