Postmortem assignment
Write the postmortem for the game-day outage in Markdown or PDF. Peer and tutor review.
Write the blameless postmortem for the game-day outage you commanded in module 3 (or for the outage simulator scenario, if you missed the drill).
Requirements
- Use the template from the resources of this topic, in Markdown or PDF.
- Timeline in UTC, from the first trigger to the all-clear, at least 8 entries.
- Impact in numbers: duration, share of requests affected, error budget consumed.
- At least three contributing factors, none of which names a person.
- At least four action items, each with an owner, a due date and a type (prevent, detect, mitigate). At least one must be detect or mitigate.
- Maximum 1,200 words plus the timeline.
Review
Your postmortem is reviewed by one peer from your cohort and by a tutor. Expect comments within three working days. Status Changes requested is normal: most postmortems need one more round.
Rubric
| Criterion | Excellent (3) | Adequate (2) | Needs work (1) |
|---|---|---|---|
| Timeline | complete, precise, sourced from the scribe log | complete but vague times | gaps or reconstructed from memory |
| Impact | quantified, linked to the SLO | partly quantified | qualitative only |
| Contributing factors | several interacting conditions, systemic | a few, some point at individuals | single "root cause" or blame |
| Action items | specific, owned, dated, balanced types | specific but missing owners or dates | generic ("be more careful") |
| Tone | blameless and readable by the whole org | mostly neutral | defensive or accusatory |
Maximum score: 15 points. Passing: 10.
