During our last SQF audit, our auditor brought up a point about how we track the changes or different versions of all of our SOP's.
Our SOP's are saved on a shard network drive and an appointed person in each department has the ability to update their own SOP's. Currently when a new version is created the old version is saved in a separate folder and kept for reference. The new version is then updated with the new version number and the reason for the update. Any small changes that do not create a new version are not tracked.
It was suggested by the auditor to use a log of some sort, but that does seem very effective or efficient when multiple people are able to edit the files.
Does anyone have any suggestions for a better method for tracking these changes?
