When working in a group that involves of doing writing projects, they should use version control software as this is a type of system that would be useful in recording a file, specifically, the writing projects that they have done in means of having a copy and to also revert files when needed.
I believe the answer is: keep track of all members' changes to the document
The version control software would provide some sort of notification for every changes made by the members who granted the permission to change the document. By doing this, the group can know which members is at fault in case they make some sort of mistake on the document.
