Mistakes are inevitable in any environment that demands thinking and risk. The real danger is hiding them, repeating them, and building a culture of denial.
So the standard becomes twofold. First: bring mistakes to the surface quickly, without shame. Second: extract the lesson and change the system so the same mistake is less likely next time.
Learning requires specificity. “Be careful” is not a lesson. A lesson names the cause, the missed signal, the flawed assumption, and the change in process. When learning is concrete, it becomes teachable.
This culture also changes behavior. People stop optimizing for looking smart and start optimizing for getting better. Over time, that creates resilience: problems are addressed early, accountability becomes normal, and improvement becomes part of the daily rhythm rather than an occasional initiative.
