# On-Call Handoff Patterns Effective patterns for on-call shift transitions, ensuring continuity, context transfer, and reliable incident response across shifts. ## When to Use This Skill - Transitioning on-call responsibilities - Writing shift handoff summaries - Documenting ongoing investigations - Establishing on-call rotation procedures - Improving handoff quality - Onboarding new on-call engineers ## Core Concepts ### 1. Handoff Components | Component | Purpose | | -------------------------- | ----------------------- | | **Active Incidents** | What's currently broken | | **Ongoing Investigations** | Issues being debugged | | **Recent Changes** | Deployments, configs | | **Known Issues** | Workarounds in place | | **Upcoming Events** | Maintenance, releases | ### 2. Handoff Timing ``` Recommended: 30 min overlap between shifts Outgoing: ├── 15 min: Write handoff document └── 15 min: Sync call with incoming Incoming: ├── 15 min: Review handoff document ├── 15 min: Sync call with outgoing └── 5 min: Verify alerting setup ``` ## Templates and detailed worked examples Full template library and detailed worked examples live in `references/details.md`. Read that file when you need the concrete templates. ## Troubleshooting **Incoming engineer misses a critical issue because the handoff document was incomplete.** Use the outgoing checklist as a gate: do not mark handoff complete until every section has at least one entry (or an explicit "none"). Make incomplete handoffs a blameless postmortem action item. **A 30-minute sync call is not possible due to timezone gaps.** Fall back to the async quick handoff template (Template 2). Supplement with a short Loom or voice memo walking through the watch list. Ensure the incoming engineer has a direct contact method if they have follow-up questions. **The incoming engineer inherits a mid-incident and is immediately overwhelmed.** Use the incident handoff template (Template 3) specifically. The outgoing engineer should remain available on Slack for 15 minutes after handoff, even if off-call, to answer clarifying questions. **On-call handoff documents are inconsistently formatted across teams.** Adopt the shift handoff template organization-wide and store completed handoffs in a shared location (wiki, Notion, Confluence). Link each handoff from the on-call schedule entry in PagerDuty. **Incoming engineer cannot verify their alerting is working before the outgoing engineer logs off.** Add a standard step: outgoing engineer fires a test alert and confirms incoming engineer receives it in PagerDuty and Slack before ending the overlap window. ## Related Skills - [incident-runbook-templates](../incident-runbook-templates/SKILL.md) — Runbooks for the incidents that are handed over mid-response - [postmortem-writing](../postmortem-writing/SKILL.md) — Turn resolved incidents from the shift into structured postmortems
