Mandatory vs. optional
Start by flagging mandatory compliance items, then separate optional supporting documents.
This keeps the team from spending time on non-critical attachments.
Audit trail discipline
Every change should be logged with date, owner, and reasoning. This makes audits painless.
Store the final version in a clearly labeled archive.
Checklist-driven delivery
Treat the compliance checklist as the master record. If it is not in the checklist, it does not exist.
