Engineering incident workflow
A root cause analysis template generator creates a structured RCA worksheet for engineering incidents, bugs, outages, and process failures. Use it to capture impact, triggering events, contributing factors, corrective actions, owners, and follow-up verification without turning the review into blame.

System conditions to examine before choosing fixes.
Actions
3
Owner-based follow-ups ready for review.
# Root Cause Analysis: Checkout deploy caused elevated API errors ## Summary Service or workflow: Payments API Severity: SEV2 - Major degradation, broken core workflow, or incident with broad user impact. Analysis method: 5 Whys ## Customer or business impact Customers saw intermittent payment failures for 28 minutes during peak traffic. ## Problem statement Checkout deploy caused elevated API errors ## Triggering event A schema migration shipped without the matching backwards-compatible reader. ## Root cause analysis Use 5 Whys to separate the triggering event from the deeper system causes. Primary contributing factors: - Migration checklist did not include rollback verification - Synthetic checkout monitor only covered happy-path card flow - Review focused on API shape, not database compatibility ## Corrective actions - Add expand-contract migration checklist - Platform - Friday - Create synthetic monitor for declined and retry payment paths - SRE - May 31 - Require rollback notes in deploy plans for payment changes - Engineering Manager - next sprint ## Verification plan - Confirm each corrective action has an owner and due date. - Add a regression check, monitor, or runbook update for the failure mode. - Review action status in the next engineering operations meeting. ## Blameless review prompts - What signals could have detected this earlier? - Which assumption was reasonable at the time but wrong in production? - What would make the safer path the default next time? - Which follow-up would reduce recurrence risk the most?
Strong RCAs separate the visible trigger from the deeper conditions that allowed the failure. The point is not to find a single person or single line of code. It is to identify the checks, defaults, alerts, docs, and ownership gaps that need to change.
Keep the template concrete. Write the impact in customer language, list contributing factors as system conditions, and make every corrective action small enough to assign, schedule, and verify in a follow-up review.
A root cause analysis template is a structured worksheet for documenting what happened, why it happened, what factors contributed, and which corrective actions will reduce recurrence risk.
Root cause analysis focuses on the causes and corrective actions behind a failure. An incident postmortem usually includes the full incident narrative, timeline, detection, response, impact, and learning review.
Yes. Blameless RCAs produce better learning because they examine systems, incentives, tooling, communication, and safeguards instead of stopping at individual mistakes.
Every RCA action item should include a specific change, a directly responsible owner, a due date, and a verification signal that proves the recurrence risk was reduced.
