One of the details which I find highly relevant to software and, particularly, operations is rejecting the mindset of dealing with failure by finding someone to blame and instead changing the system so that one person can't inadvertently cause a failure. I see this a lot with massive ops run books which require humans to repeatedly perform complex tasks without mistake rather than automating it and regularly testing your automation.
