For ML Engineers · Incident postmortem

ML incident postmortems for ML engineers who prevent the next failure.

ML incidents — serving failures, performance degradation, prediction quality drops — require postmortems that understand both the ML and systems dimensions. The whiteboard session is where both are analyzed. BoardSnap turns it into a documented analysis before the window closes.

Why ml engineers love this workflow

ML incident postmortems are more complex than standard engineering postmortems. The failure might be in the serving infrastructure, or it might be a model quality issue triggered by data distribution shift, or it might be a feature pipeline failure that fed bad data to the model. All three require different root causes and different remediations.

BoardSnap reads the multi-dimensional ML incident postmortem — the serving timeline, the model quality analysis, the data pipeline investigation, and the monitoring gaps — and produces a structured document that covers all failure dimensions.

The exact flow

  1. Map the ML incident timeline

    Show the serving failure timeline, the model quality degradation curve, and any upstream data events that may have triggered the issue.

  2. Investigate the failure dimensions

    For each dimension — serving infrastructure, model quality, data pipeline — list the evidence and rate the contribution to the failure.

  3. Name the root cause

    After evaluating all dimensions, write the root cause. Be specific: 'Feature X distribution shifted 3 standard deviations due to upstream schema change.'

  4. Define monitoring and remediation actions

    List specific monitoring improvements, model quality checks, and data validation steps. Assign owners.

  5. Snap the postmortem board

    Open BoardSnap and capture the full analysis — timeline, root cause, and action items across all failure dimensions.

What you'll get out of it

  • All failure dimensions — serving, model quality, data pipeline — are analyzed in one document
  • Root cause is named specifically, not vaguely attributed to 'model drift'
  • Monitoring improvements are designed during the postmortem, not after it
  • The postmortem is shareable with data science and platform teams
  • ML incident history tracks whether monitoring improvements actually prevented recurrence

Frequently asked

Can BoardSnap read multi-dimensional failure analysis diagrams?

Yes. Multi-section boards with different failure dimensions — serving, model quality, data pipeline — are captured by BoardSnap with each section's analysis preserved separately in the output.

How is an ML incident postmortem different from a standard engineering postmortem?

ML incidents require investigation across multiple dimensions — the ML model, the feature pipeline, and the serving infrastructure. The root cause might be any of them or a combination. BoardSnap reads whatever structure you use for the analysis.

Can we use this postmortem to improve our model monitoring?

Yes — that's a primary use case. The failure analysis identifies exactly which signals were missing from monitoring. Use the postmortem output to define new monitoring thresholds and alerting rules before the next deployment.

How quickly after an ML incident should we run the postmortem?

Within 24-48 hours, while the investigation findings are fresh. BoardSnap makes the documentation fast — the session output is ready to publish before the team scatters.
