@tychotithonus @robertatcara at one company I worked for in the late 1990’s (one of the biggest banks in the world though I worked for a services firm) we went from 1200 internally written apps to around 600 in preparation for Y2K.
A business leader was given an option - if they didn’t want to update their app to the bank’s standards they could sign a written statement that their app was not mission critical and they could have gotten an exception. No one took that “deal”
