The handoff is where outages are born (and the 5-line fix)

Most incidents don't start with a failure - they start with a shift handoff that lost one sentence.

What actually gets lost

Not the runbook. The state: "replica 3 is still catching up", "we upgraded the driver at 14:00", "the vendor ticket is open". State is context, and context is exactly what a checklist template can't carry.

The 5-line fix

End every handoff with five lines, typed by the outgoing engineer:

1. What is on fire right now (or "nothing")
2. What we changed in the last 12h
3. What we're waiting on from someone else
4. What I'd check first if it breaks
5. The one thing I'm worried about

Line 5 is the magic one - the outgoing engineer's unease is the cheapest early-warning system you own.

It takes 90 seconds per shift and it will pay for itself the first time the next shift doesn't re-diagnose a live fault from scratch.

Templates + the full shift-ops system are in the 24/7 Ops Kit. More free guides: dev.to/hive80lab.
