First move
Start with the 1 of 4 artefacts that already live in a system (Vendor register / contract repository); keep the periodic reviews but log each one as a dated record with a named reviewer.
Common gaps auditors find
- Directory kept in spreadsheets that omit the start of service usage date
- Named contact persons left unchanged after staff departures on either side
- Processing location recorded at company level rather than country or facility level
- No annual verification of directory content ever performed
