Write for the person responding under pressure
A first runbook should be short enough to use during an interruption. Start with how to recognise the incident, who coordinates it and where the team records actions. Include an escalation contact when the usual engineer is unavailable. Avoid a document that lists every hypothetical disaster while leaving basic access unresolved. The responder needs a path from observation to a safe next decision.
Separate coordination from investigation
Even a small team benefits from knowing who is investigating and who is keeping the incident record current. Google’s SRE incident guidance provides a useful model for clear roles. Adapt the scale to your team rather than copying a large organisation’s ceremony. Record material actions and their times so the team can understand what changed. Without that record, simultaneous fixes can make the system harder to diagnose.
Rehearse one realistic scenario
Choose a specific failure, such as paid orders not receiving confirmation. Identify the customer impact, the first check and a reversible containment action. Discuss whether new orders should be paused. Use a tabletop exercise or controlled staging failure rather than disrupting customers. The purpose is to uncover missing permissions, unclear ownership and assumptions about external support before those gaps become part of a live incident.
Define recovery evidence
Agree what must be true before the team declares service restored. A restarted process may still leave incomplete orders or delayed jobs. Check the affected customer journey and identify records needing reconciliation. Assign responsibility for follow-up work and customer communication through the authorised channels. Avoid announcing a complete resolution merely because an infrastructure graph recovered while the business workflow remains inconsistent.
Improve the system after the event
Review the sequence without reducing it to who made a mistake. Identify changes that improve detection, limit consequences or simplify recovery. Keep actions small enough to assign and verify. Update the runbook with what actually helped. A document that survives only as an onboarding attachment is not operational preparation; a rehearsed procedure connected to access, monitoring and ownership can materially improve the next response.

Evidence to take into your own review
Define the code revision and scope. For each finding, record the affected flow, the steps that reproduce it, its business consequence and the evidence for the next action. After a fix, repeat the check and record what remains uncertain. An audit delivers a verdict; remediation and verification are separate steps.
