I believe this is pretty common in the financial sector and in some cases the problem boils down to the source for an application being lost, but often it is due to a "leave well enough alone mentality" and when changes are needed they look for solution that require the minimum amount of change. A friend who worked as a programmer for a large insurance company told me they resolved the Y2K problem in a large database on an IBM mainframe by a simple change. It had been designed with a two digit year which was stored in packed decimal which would require two bytes because of the sign nibble and one digit nibble would always be zero so for anything after 2000 they simply changed that nibble to a non-zero value which only require minimal changes to the program and none to the database itself. |
