Retention is different from current status

Teams need to preserve historical evidence without confusing it with the currently approved record.

Retain decision context

The evidence file alone may not explain why it was accepted. Keep reviewer, approval date, requirement mapping and relevant methodology context.

Separate retention rules by record type

Certificates, questionnaires, regulatory calculations and buyer submissions can have different contractual or regulatory retention needs.

Design deletion as a controlled process

Retention policies should define when records can be removed, who approves deletion and what audit information remains.
