Everyone has runbooks and nobody opens them mid-incident. What makes a runbook people actually use?

Usable runbooks live one click from the alert, front-load symptom-to-action pairs, and stay alive because CI and drills force the issue rather than anyone hoping.

Grounded in researched DevOps, SRE and platform engineering interview loops, written to a senior-engineer editorial bar, and never padded to hit a word count.
