Writing a runbook is a declaration of temporary failure.
The act of writing a runbook is the incantation to a dark, forbidden contract with the better angels of our nature. It is a promise to do the right thing in the future, but not now. Right now, we're going to do the evil thing: write a runbook.
How often do we go back and do the right thing?
Rarely.
How many of these promises do we break?
A lot of them.
An error doesn't become a mistake until you refuse to correct it.
If you have runbooks, consider them as backlog tasks. Try not to add to their numbers. Failure begets runbooks; runbooks beget runbooks; and runbooks beget failure.
