What is a blameless postmortem?

A blameless postmortem is an incident review process that focuses on systemic failures and environmental conditions rather than individual human error, encouraging transparency to drive long-term reliability.

Can I use this for minor incidents?

Yes, it includes a 'Quick Postmortem' template specifically designed for minor issues (SEV3+) that require documentation without the overhead of a full-scale meeting.

Is this based on industry best practices?

Yes, the methodology follows established SRE principles used by organizations like Google and Etsy to foster a culture of continuous learning and operational excellence.

How does this skill help with root cause analysis?

The skill provides structured frameworks like the '5 Whys' and templates to help teams move beyond the immediate trigger to find the underlying technical or process gaps.

Does it support action item tracking?

While the skill generates the structured action item list with owners and priorities, these can be easily copied into task management tools like Jira, GitHub Issues, or Linear.
