Mining incidents for systemic causes
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
turn a pile of postmortems into a few systemic findings.
Planned topics
- Use a common tagging scheme: trigger, contributing factors, detection, recovery.
- Count by tag across teams, not only within one.
- Look for patterns: deploys without rollback, missing alerts, shared dependency failures.
- Share findings with the teams; they know the context and will correct you.
Draft outline details
Demonstration
a table of 30 incidents tagged by cause, with counts: "no safe rollback" 11, "alert missed" 9, "dependency overload" 6.
