In the expedition metaphor, the danger is not only the obvious storm. A new explorer may be overwhelmed because they do not understand the terrain. A very experienced explorer may become complacent because the terrain feels familiar. The productive middle is being experienced enough to know what matters, but alert enough to keep checking.
This is not fear. It is prepared vigilance. In performance partnering, the quiet failure mode is a dashboard that still refreshes while the measure no longer means what directors think it means.
