Overview
Engineering Postmortem is a role-based workspace for coordinating a blameless review of a P0/P1 production incident. Its four stage-based task lists move the team from incident context and containment to timeline and causal analysis, action planning and prioritization, then publication and follow-through. Milestones mark when scope, impact, and evidence are confirmed; analysis is complete; actions are assigned; the postmortem is approved and published; and the first verification review is held. A P0/P1 postmortem progress hill chart gives the team a shared view of uncertainty and progress.
The member slots represent functions, not preselected people: an Incident Commander, Postmortem Facilitator, Engineering Manager, Service Owner, Technical Investigator, Site Reliability Engineer, Customer or Support Representative, and Security or Compliance Reviewer. Assign actual participants when cloning the workspace, and make one person the DRI for each task or action. The two check-ins support review progress and later action verification; set each to a specific cadence or date before the review starts. The target is to identify root cause and define action items within five business days, while the verification milestone keeps the work from ending at publication.
Use this template when a significant production incident warrants cross-functional analysis and tracked corrective work. It is not a live incident command workspace, an automated incident-data importer, or a substitute for your organization’s security, legal, or regulatory process. For a low-severity event that needs only a brief note, trim the workflow or use a lighter-weight record rather than forcing every milestone. Conway’s Law is a useful design check: assign role slots and handoffs to match how your services and teams actually operate.
Standards & compliance context
- Treat the workspace as a coordination aid, not proof that a regulatory, contractual, or internal incident-review obligation has been met.
- Ask the Security or Compliance Reviewer to identify any applicable notification, privacy, evidence-retention, or approval requirements for the specific incident.
- Follow approved access, data-handling, and retention procedures when recording logs, customer impact, or security-sensitive details.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.

Postmortem approved and published
The blameless postmortem is reviewed, approved, published, and communicated to relevant stakeholders.
-
First action-item verification review
High-priority corrective actions are reviewed for evidence, blockers, and escalation needs.
To-do lists
-
Incident context and containment
Establish the incident record, scope, impact, and containment facts before analysis.
-
Timeline and causal analysis
Reconstruct the event sequence and identify root and contributing causes using evidence-based analysis.
-
Action planning and prioritization
Turn findings into measurable, owned corrective actions prioritized by risk reduction and implementation effort.
-
Publication and follow-through
Approve the postmortem, communicate learning, and track action-item verification after publication.
Hill charts
-
P0/P1 postmortem progress
Track each workstream from uncertainty to verified completion, with the five-business-day publication goal as the initial target.
How to use this template
- Clone the workspace, confirm the incident’s P0/P1 scope, and tailor task-list details, milestones, and visibility to your review policy.
- Assign each role slot to a participant, name the Incident Commander and Postmortem Facilitator, and give every task and action a clear DRI.
- Populate Incident context and containment with impact, response decisions, and available evidence, separating confirmed facts from assumptions.
- Build the event timeline and causal analysis from evidence, then review open questions with the relevant service and technical owners.
- Prioritize corrective actions, set owners and completion criteria, and move the workspace through approval and publication milestones.
- Use the action-item verification review to check evidence of completion, update unresolved work, and record any follow-up needed.
Best practices
- Keep the review blameless by describing system conditions, decisions, and contributing factors rather than framing individuals as causes.
- Record evidence and timestamps while they are available, and label hypotheses clearly until they are verified.
- Give each task and corrective action one DRI, with consulted reviewers identified separately when needed.
- Use the milestones as decision gates: do not start prioritizing actions until the scope, impact, and evidence are sufficiently clear.
- Set the progress check-in to a named cadence, such as Weekly Mondays or daily during the review window, and schedule verification separately.
- Prioritize actions by risk reduction and practical impact, using RICE where comparable options need a consistent method.
- Keep default visibility appropriate for incident sensitivity and confirm access before adding customer, security, or operational evidence.
- Use the hill chart to surface uncertainty in causal analysis, not as a substitute for evidence or a completion checklist.

Common use cases
Frequently asked questions
What incidents is this postmortem template designed for?
It is structured for P0/P1 production incidents that need a coordinated review, documented impact, causal analysis, and follow-through. The task lists cover containment and context, timeline and analysis, action planning, and publication. For lower-severity events, remove steps that do not fit your review policy rather than treating the template as a mandatory process.
How often should the postmortem check-ins happen?
Set the progress review to a defined cadence, such as a brief daily review during the five-business-day drafting window. Schedule the action-item verification review for the point when owners can report evidence of completion, not simply when the postmortem is published. Update the cadence to match incident duration and your organization’s operating rhythm.
Who should own and run the review?
The Incident Commander coordinates the handoff from incident response, while the Postmortem Facilitator runs the blameless review and keeps the analysis focused on systems and conditions. The Service Owner and Technical Investigator contribute service context and evidence; the Engineering Manager helps resolve ownership or priority conflicts. Use the Customer or Support Representative and Security or Compliance Reviewer when the incident’s impact or review scope calls for their input.
Does using this template make a postmortem compliant with regulations?
No template alone establishes compliance with a law, contract, or internal policy. The Security or Compliance Reviewer should determine whether the incident triggers notification, evidence-retention, privacy, or other obligations, and record applicable deadlines in the workspace. Follow your organization’s approved incident and legal review procedures.
What are common mistakes when completing a postmortem?
A frequent pitfall is treating the first plausible explanation as the root cause before the timeline and evidence are reviewed. Teams also lose follow-through when actions have no DRI, target date, or verifiable completion condition, or when the write-up is published without an action-item review. Keep the analysis blameless and distinguish confirmed facts from hypotheses.
Can I customize the roles, milestones, and review steps?
Yes. Replace role slots with the functions needed for your incident process, while keeping roles rather than individual names so each cloned workspace can assign its actual participants. Adjust milestones, task lists, and check-in cadence to reflect your severity definitions, approval path, and service ownership model. Preserve clear handoffs from evidence to analysis, assigned actions, publication, and verification.
Does this workspace include integrations or automatically create incident records?
The template provides a workspace structure: role slots, task lists, milestones, check-ins, a hill chart, and a welcome post on the message board. It does not automatically import incident data or create integrations, so the Incident Commander or Service Owner must bring relevant context and evidence into the review workflow. Confirm access and handling rules for any evidence before sharing it in the workspace.
How should we roll this out after cloning the template?
Assign the Incident Commander and Facilitator first, then fill the remaining role slots with people suited to the incident’s scope. Confirm the five-business-day target, check-in cadence, publication approver, and first verification review before work begins. At the end, capture lessons about the workflow itself and update the template for future incidents.
How is this different from an ad-hoc document or meeting?
An ad-hoc document can capture a narrative, but it often leaves review ownership, action DRIs, milestones, and verification timing implicit. This workspace separates context, analysis, action planning, and publication into stage-based task lists, with milestones that make progress visible. Teams can still publish a final narrative in their chosen format while using the workspace to coordinate the work around it.
