This is generally true. Patiently documenting steps as well as logging any corrective and preventive actions (something that I learnt when studying for ISO 9001) is prudent.
I (mostly) stopped documenting in prose and used ansible instead. It's a bit more work, but it paid off numerous times since then. The prose that's still left, because it's really really to cumbersome to implement, is left in the comments of ansible files.
