A Practical One-Page Runbook Template for On-Call Engineers

Software engineer Dr. Samson Tanimawo has shared a concise runbook template designed to help on-call teams respond to incidents quickly and effectively. The template covers seven key sections: the trigger alert, its impact, the single most useful first command, the top three common causes, a copy-paste fix for each cause, escalation contacts with timezones, and post-incident follow-up steps. Tanimawo argues that most existing runbooks fail because they are either too vague or too lengthy to be useful during a late-night incident. The goal is to give an engineer the next clear action within 30 seconds, without requiring heavy cognitive effort. He recommends starting with the team's noisiest alert, validating the runbook with a new team member, and repeating the process for the top ten alerts to cover the majority of on-call scenarios.
