Question
📝 **Question:** Most-quoted feature of a good postmortem? 📋 Pick the right answer. 💡 **Hint:** Re-read the theory above if unsure.
A

B
Blameless tone + concrete owned action items with deadlines. Tone determines whether next incident is reported.
C
A public Notion link — sharing the postmortem widely demonstrates company-wide commitment to operational transparency.
D
