There are many old systems that still get used in
regulated labs, and the systems work perfectly fine to do
what they do. But the work-around for this is a heavy dose of
procedural controls that would include handwritten records.
Depending on the criticality and the risk of the particular
process that’s involved, or that the system is addressing, the
procedural requirements may need to go as far as a second
person verification of information or actual concurrent
witnessing of the work being performed. The purpose of the
audit trail is to be able to tell the story or reconstruct the
history of an electronic record, not just the creation of that.
