It lists named contacts, decision points, escalation paths, and the specific actions taken in the first hours of an incident when executive bandwidth is constrained. - A good runbook has six elements: contact list with current numbers, decision tree for severity classification, escalation matrix, immediate action checklist, communication templates, and post-incident review structure. - The COO question is not whether the runbook exists. It is whether the runbook works at 2 a.m. on a Sunday with executive bandwidth constrained.   ## The Six Elements an Incident Response Runbook Must Include 1. Contact list (current numbers). 2. Decision tree (severity classification). 3. Escalation matrix. 4. Immediate action checklist. 5. Communication templates. 6. Post-incident review structure.   ## Four Signs the Runbook Will Actually Hold Up During an Incident 1. Recent tabletop exercises that exercised the runbook. 2. Updated contact information. 3. Named owners for each section. 4. Integration with external counsel and forensic resources.   ## Why "It's Documented" Isn't Enough If It's Never Been Exercised A COO will hear: the runbook is documented, that is sufficient. False if not exercised.   ## Runbook Design and Quarterly Tabletops That Keep the Plan Current A COO should work through runbook design and quarterly tabletop exercises.   ## Exercise the Runbook Before the Incident Does It for You The runbook works under pressure or it does not. Exercise reveals the difference. If your bank has not exercised the runbook in the last twelve months, that is the conversation worth having with your Tech-Operations partner. Five Nines Technology Group is the Tech-Operations partner for community banks and credit unions. We focus on helping COOs design IR runbooks that work at 2 a.m. on Sunday. ## Frequently asked questions How often should the runbook be exercised? Quarterly tabletop minimum, annual full exercise. Who maintains the contact list? Named owner with quarterly review. Should the board see the runbook? Summary form; substantive review by audit/risk committee. How does external counsel integrate? Pre-engaged with retainer, contact info in runbook. What about cyber insurance contacts? Carrier and broker contacts in runbook. How does this interact with FFIEC examination? Examiners review runbook quality. What about cloud platform incidents? Vendor coordination procedures included. ## Related Blog Posts [![What Good Looks Like: A Fractional Security Executive Engagement That Justifies Its Budget](https://blog.fivenines.com/hubfs/blog/taya-migration/33-good-fractional-ciso-engagement-cfo.docx.png)](https://blog.fivenines.com/what-good-looks-like-a-fractional-security-executive-engagement-that-justifies-its-budget) #### [What Good Looks Like: A Fractional Security Executive Engagement That Justifies Its Budget](https://blog.fivenines.com/what-good-looks-like-a-fractional-security-executive-engagement-that-justifies-its-budget) Why the Fractional Engagement Renewal Deserves Substantive CFO Scrutiny A community bank CFO walking into the fractional engagement renewal is rarely...
