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

Mostly documents and reviews. Pull the 1 system-held artefact from your Backup / DR tooling on a schedule; put the documents under version control with an owner and review date, and log each review as a dated record with a named reviewer.
