Interesting article on change management.

I have see this accomplished several different ways.
All backups and version changes are kept on the server. Standard practice is the review the current backup with the version running in the machine. If they are the same then modify, document and save to next version.
If the current backup is different then save a copy of the with the next version number. Modify , document and save to the next version.

Hope this helps,

The problem with MDT and Rockwell's version of it is that they work best if everything is networked together. Working with multiple sites and multiple automation techies the best I can do is make everyone store the files on a networked drive with a spreadsheet documenting changes for each processor.

I personally try to stay away from spreadsheets. At the beginning of the program is a block of documentation with all of the revisions. Everything is on a networked, backed up each night.
