I listen to the calls weekly. No one shouts. No one degraded others. Cbell's power is that he doesn't have an ego in these calls.

The blameless postmortems are reviewed in these meetings, and the findings challenged, to ensure they really got to the root cause and lessons are learned.

I once almost got to present my post mortem, but it wasn't high enough priority that week. I wish it had been. It would have been ripped apart, but I would have gotten the feedback from the smartest people in the company on how to make my system better.
