tl;dr: When something goes wrong, skip the detailed explanation of why—reasonable people usually made reasonable decisions given their constraints, and empathizing with the causes tends to kill any urgency to change. Instead, ask what systemic change will prevent the same class of failure next time; vague commitments like "we'll communicate better" are organizational folklore, not fixes. Accepting a risk consciously is fine, but only if it's a deliberate choice rather than a way to avoid actually changing the system.
