Re: "always assume the document will be read..."
One of the documents I wrote here at [RedactedCo] was the tape rotation process for one of the LOB servers that handles a gargantuan amount of financial transactions every day.
The document was written so that a non-terchnical person could comprehend and follow it. it was approved, and handed out to the frontline staff to use.
fast forward ~ 11 months, and we had a request to perform a restore from one of the tape backups. Only problem is that we couldn't find it anywhere.
The short, public version is that the people running the backups for the past, oh, 10 months have not been following the procedure (one of them even proclaimed that he didn't bother reading it), so the application's archive tapes have missing and incomplete data sets. After I put my jaw and eyes back in my head, I explain to the BSA for that app that there might be a way to recover the data from the monthly system backups, even though we've never tried it in that manner. He says, 'if we can pull that off, that'd be great', so after he finishes his smoke and I have my cool down, we go back in side, and I start researching what tapes I need to have the Copper Hill people bring back in the morning. Then about 15 minutes later, I go up and start looking for our boss with visions of torture even such that the Marque De Sade would find cruel and unusual to see if I can get two people fired, and charged with a couple counts of general stupidity.
THE [Redacted] [HOLY CRAP redacted] [Seriously, with a MONKEY?!] TECH DIDN'T DO A SINGLE WEEKLY OR MONTHLY BACKUP AT ALL FOR FOUR MONTHS.
And that was my first ever data loss incident. We decided shortly afterwards to take back ALL the backup duties away from that group during the big upgrade of that application.
