*The* standard for government work
(shameless repost from last week)
Peon creates excel sheet (in their own time) that stores details, then upgrades it a bit so it automatically sends emails, or something.
Their manager sees it, and mentions it to their boss as a Good Thing.
Boss tells their boss, everyone gets access to it, and before you know it everyone is using it.
Original peon leaves for a better job.
Six months later the thing is overloaded, or stops working, or an Office upgrade renders it useless. Meanwhile it has become "business critical" and there is a Massive Flap (tm) while IT get the blame for it not working.
Repeat ad nauseum.
