00:00 - 00:02Dimitri is on-call tonight
00:02 - 00:04And he's drunk
00:05 - 00:06Let me explain
00:07 - 00:08Wait
00:08 - 00:11That's not very responsible
00:12 - 00:13It is when your systems are reliable
00:13 - 00:16and you do agile post-mortems
00:16 - 00:18What are agile post-mortems?
00:18 - 00:21There's a leaner post-mortem process
00:21 - 00:25not perceived as a bureaucratic burden
00:25 - 00:27The goal is to understand how an accident could have happened
00:28 - 00:29There is no root cause in complex socio-technical systems
00:30 - 00:33So we just address the single most impactful change we can do
00:34 - 00:37that will make our system more resilient, and we get it done.
