Audit readiness starts before the audit

A team is ready when the evidence behind important claims is already organized, current and approved rather than collected in a rush after a request arrives.

Preserve source and context

Each record should show where it came from, what requirement it supports, who reviewed it and whether it is still current.

Make exceptions visible

Missing or expired evidence should create an explicit task or exception instead of being buried in a shared drive.

Use the same record for recurring reviews

A reusable evidence layer reduces repeated collection and creates consistency across buyers, auditors and internal reviews.
