I have never written a runbook. And I refuse to ever do so.
Writing a runbook is a deliberate declaration of failure. It is the explicit process that recites a refusal to correct an error. [An error doesn't become a mistake until you refuse to correct it.]/writing/an-error-is-not-a-mistake)
If your organization has runbooks, consider them as backlog tasks: automation, redesign, and architecture improvements. Do not add to their numbers. Failure begets runbooks; runbooks beget runbooks; and runbooks beget failure.
