Every bad incident night starts with a bad handover. The on-call engineer inherits a system they don't understand, at 2AM, and spends the first 40 minutes just figuring out what is even broken — while the outage clock keeps running.
After too many of those nights, I built a 15-minute handover ritual. It fits on one page. Here it is.
The 5 sections
1. What's on fire right now (or "nothing")
Open tickets, flapping alerts, anything in a degraded state. One line each: what, since when, what's been tried.
2. Changes shipped in the last 72 hours
Deploy list, config changes, infra changes. 80% of new incidents map to a change made in the last 3 days. If you know what changed, you know where to look first.
3. The known landmines
Things that will break but nobody has fixed yet: the cron that deadlocks on Sundays, the disk at 91%, the third-party API that rate-limits every night. If a landmine explodes tonight, the next person shouldn't be discovering it.
4. Runbook pointers (not runbooks)
For each critical service: where the runbook lives, where the dashboards live, where the escalation list lives. Links only. The handover is a map, not a manual.
5. "Do NOT touch" list
Fragile components where a well-meaning fix makes things worse. Name them explicitly. This line has saved me more times than any monitoring tool.
The 60-second test
Hand your write-up to someone else on the team. If they can answer "what would you do first if every alert fired right now?" in under 60 seconds without asking you anything, the handover passes. If not, rewrite the missing piece.
Why this matters more than fancy tooling
Teams spend thousands on observability but still lose 40+ minutes per incident to orientation: who owns this, what changed, what's already been tried. A one-page handover kills that tax. It's the cheapest MTTR reduction that exists — it costs a pen and 15 minutes.
If you want the full version — a fill-in handover template plus the incident-response checklists I use (first-5-minutes flowchart, comms templates, postmortem skeleton) — I packaged them here: hive80lab.gumroad.com. Print them, laminate them, sleep better.
Stay calm and rotate well. 🌙
