As Kathy brought up the most important part in naming the final document is to Identify the document without even opening it.
I am providing my sample of naming the documents that might help you out.
“Naming Convention (Trial Level)
(ProtocolNumber_DocumentType_Sub-artifacts short name/Document Description_Documnt date)”
“Naming Convention ( Country Level)
(ProtocolNumber_Country_DocumentType_Sub-artifacts short name/Document Description_Documnt date)”
Country:- 2 or 3 digit ISO code
“Naming Convention ( Site Level Level)
(ProtocolNumber_Country_Site Number_Last Name of PI_DocumentType_Sub-artifacts short name/Document Description_Documnt date)”
For documents related to CV’s and MLS we also capture the Name of the CV and MLS holder.
Sub-artifacts short name/Document Description :- Provides a short description about the document content. Becomes very important and makes it easy to identify a document by just looking at the Document name.
Hope this helps.
