Software Development and Postmortems

https://vadimkravcenko.com/shorts/dealing-with-failures-and-postmortems/

TL;DR;

Incidents are going to happen. Systems will fail, code will break, and sometimes, despite your best efforts, things will go south.
How you handle it matters.
Communication matters.
Learning from incidents matters.
When shit hits the fan, keep your cool, rally your team and keep them informed.
