where the evidence lives

teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

First move

No system holds this evidence for you: it is people and documents. Reminders and routing to the owner still save time. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date.

Common gaps auditors find

Usage data reused for product analytics or marketing beyond the permitted purposes
Anonymisation claimed while tenant or user identifiers remain in the data set
No deletion trigger, so metadata accumulates for as long as storage allows
Metadata shared with affiliated companies without a contractual basis
