We need a document management system or process that only allows certain users to either delete or replace an existing file, or add a new file.
A junior staff member will upload a file, and then a senior manager and 1 other staff member must accept the document (a pdf) and the system will then add it to the final library of files, under certain categories. It needs to be easy to use!
So there would need to be an admin area to select the junior and senior staff members who can add new documents or can approve new documents. Only once there are 2 approvals can the document replace, delete or be added to the library.
