• Needs to design or improve an on-call rotation or escalation policy
• Wants to write, review, or templatize a runbook for an alert or service
• Is conducting, writing, or facilitating a post-mortem / post-incident review
• Needs to set up or improve a status page and customer communication strategy
• Is running or setting up a war room for an active incident
• Wants to define severity levels or incident classification criteria
• Needs an incident commander playbook or role definitions
• Is building incident response tooling or automation

• Defining SLOs, SLIs, or error budgets without an incident context (use site-reliability skill)
• Infrastructure provisioning or deployment pipeline design (use CI/CD or cloud skills)

1. Incidents are system failures, not people failures - Every incident reflects a gap in the system: missing automation, insufficient monitoring, unclear runbooks, or architectural fragility. Blaming individuals guarantees that problems get hidden instead of fixed. Design every process around surfacing systemic issues.
2. Preparation beats reaction - The quality of incident response is determined before the incident starts. Well-written runbooks, practiced war room protocols, pre-drafted status page templates, and clearly defined roles reduce mean-time-to-resolve far more than heroic debugging during the incident.
3. Communication is a first-class concern - Customers, stakeholders, and other engineering teams need timely, honest updates. A status page update every 30 minutes during an outage builds trust. Silence destroys it. Assign a dedicated communications role in every major incident.
4. Every incident must produce learning - An incident without a post-mortem is a wasted failure. The post-mortem is not paperwork - it is the mechanism that converts a bad experience into a durable improvement. Action items without owners and deadlines are wishes, not commitments.
5. On-call must be sustainable - Unsustainable on-call leads to burnout, attrition, and slower incident response. Track on-call load metrics, enforce rest periods, and treat excessive paging as a reliability problem to fix, not a cost of doing business.

Primary on-call:    First responder. Acks within 5 min (SEV1) or 15 min (SEV2).
Secondary on-call:  Backup if primary misses ack window. Auto-escalated by pager.
Manager escalation: If both primary and secondary miss ack. Also for SEV1 war rooms.

• Rotate weekly. Never assign the same person two consecutive weeks without a gap.
• Minimum team size for sustainable on-call: 5 engineers (allows 1-in-5 rotation).
• Follow-the-sun for distributed teams: hand off to the next timezone instead of paging at 3am. Each region covers business hours + 2 hours buffer.
• Provide comp time or additional pay for after-hours pages. Track and review quarterly.

Hour 0:     Incident resolved. IC assigns post-mortem owner.
Day 1:      Owner drafts timeline and initial analysis.
Day 2-3:    Facilitated post-mortem meeting (60-90 minutes).
Day 3-4:    Draft published for 24-hour review period.
Day 5:      Final version published. Action items entered in tracker.
Day 30:     Action item review - are they done?

1. What happened? (factual timeline with timestamps)
2. Why did it happen? (root cause analysis - use the "five whys" technique)
3. Why was it not detected sooner? (monitoring and alerting gap)
4. What slowed down the response? (process and tooling gap)
5. What prevents recurrence? (action items)

Components:
  - Group by user-facing service (API, Dashboard, Mobile App, Webhooks)
  - Each component has a status: Operational | Degraded | Partial Outage | Major Outage
  - Show uptime percentage over 90 days per component

Incidents:
  - Title: clear, customer-facing description (not internal jargon)
  - Updates: timestamped entries showing investigation progress
  - Resolution: what was fixed and what customers need to do (if anything)

Maintenance:
  - Scheduled windows with start/end times in customer's timezone
  - Description of impact during the window

• Use plain language. No internal service names, error codes, or jargon.
• State the customer impact first, then what you are doing about it.
• Never say "no impact" if customers reported problems.
• Include timezone in all timestamps.

Minute 0-5:   IC opens the war room (video call + shared channel).
              IC states: incident summary, current severity, affected services.
              IC assigns roles: Communications Lead, Technical Lead, Scribe.

Minute 5-15:  Technical Lead drives initial investigation.
              Scribe starts the timeline document.
              Communications Lead posts first status page update.

Every 15 min: IC runs a checkpoint:
              - "What do we know now?"
              - "What are we trying next?"
              - "Do we need to escalate or bring in more people?"
              - "Is the status page current?"

Resolution:   IC confirms the fix is deployed and metrics are recovering.
              Communications Lead posts resolution update.
              IC schedules the post-mortem and assigns an owner.
              War room closed.

• One conversation at a time. IC moderates.
• No side investigations without telling the IC.
• All commands run against production are announced before execution.
• The scribe logs every significant action with a timestamp.
• If the war room exceeds 2 hours, IC rotates or brings a fresh IC.

1. Severity escalation delays compound MTTR - The most common cause of a 2-hour incident that should have taken 30 minutes is a 45-minute delay in escalating from SEV3 to SEV2. The escalation rule "if no mitigation progress after 30 minutes, escalate one level" is not optional - build it into your pager escalation policy as an automatic trigger, not a judgment call.
2. Post-mortem action items decay without a 30-day review - Action items written in the heat of post-mortem often get deprioritized as new features take over the sprint. Without a mandatory 30-day follow-up meeting with the IC and action item owners, the same incident repeats within 6 months. Treat action item review as a blocking ceremony, not a nice-to-have.
3. Status page updates that use internal jargon erode customer trust - Saying "the Kafka consumer group is lagging due to a partition rebalance" confuses customers and implies you don't know how to communicate. Customers need to know the symptom they're experiencing, whether you're aware, and when you expect resolution. Translate everything to user impact before posting.
4. War rooms without a single Incident Commander devolve into chaos - When multiple senior engineers simultaneously investigate, propose fixes, and run commands against production without coordination, changes step on each other and the true root cause gets masked by noise. The IC role is not debugging - it is traffic control. Assign an IC before anyone runs a single query.
5. Runbooks that haven't been tested under stress are not runbooks - A runbook that works when you write it (calm, familiar with the system, full context) may be unusable at 3am by a tired on-call engineer seeing the service for the first time. Run fire drills where engineers who didn't write the runbook follow it end-to-end. Gaps in instructions surface immediately.
