You do not need 100% automation. What you need is a systematic approach to handling problems followed by fixing the root cause.
Runbooks came from techops in broadcasting, power plant operations, etc where there was a clear division between operators who pushed buttons, ran cables, etc and those that made decisions about buttons to push and cables to run. Dumb hands + runbooks created "smart hands".
You are not Google scale. Don't invent a pen that writes in space when a pencil would do the trick.
