The basics, in plain English

After an incident, you write a postmortem, a document explaining what happened and how to prevent it next time. Blameless means you focus on fixing the system, not punishing people. When people are not afraid of blame, they share the full truth and everyone learns more.

Postmortem
A write-up after an incident describing what went wrong and why.

Root cause
The real underlying reason the incident happened.
Timeline
A step-by-step record of what happened and when.

Blameless

People act reasonably given what they knew. Postmortems examine systemic causes and produce concrete fixes, not blame.
