An on-call engineer gets an alert about a customer-facing problem. A runbook helps them respond without relying solely on a teammate’s memory. It records who owns a system and how to maintain it or resolve known problems. section 10.1.5 section 12.2.5
A runbook complements broader documentation: service descriptions and design diagrams explain how components fit together, while the runbook focuses on operational procedures. An SLA sets response expectations; it does not replace troubleshooting guidance. section 12.2.5
A useful runbook can bring together:
- Common customer problems and the resolutions the team has found. section 10.1.5
- System ownership and procedures for maintenance and problem resolution, especially when different teams own different components. section 12.2.5
- Relevant monitoring alerts, so responders can reach guidance quickly during an incident. section 12.2.5
Keep it current as new problems arise. Contributions from the team can improve on-call response and make later handovers easier. Documenting runbooks is also part of the continuous improvement encouraged by DevOps. section 10.1.5 section 12.2.9
