Begin with the objective being assessed
A useful artifact answers a specific question about a requirement or assessment objective. Evidence can include configurations, records, policies, demonstrations, interviews, and operational outputs, depending on the objective. A screenshot with no date, system context, or explanation may be difficult for a reviewer to interpret.
Give every artifact a home
Record a descriptive name, requirement mapping, system, owner, capture date, access location, and review date. Explain what the artifact demonstrates and any limitations. Keep sensitive evidence in access-controlled storage. A public website should explain evidence organization without collecting real assessment artifacts from visitors.
Check quality before quantity
Review whether an artifact is current, covers the actual assessed environment, and supports the statement being made. Three redundant screenshots do not repair an unsupported objective. Include enough context for an authorized reviewer to understand the safeguard while minimizing unnecessary exposure of personal information or secrets.
Plan for retention and integrity
The CMMC rule includes six-year retention of assessment artifacts for Level 2 self-assessments as well as Level 2 and Level 3 certification assessment pathways. The certification pathways also specify hashing and integrity records for their evidence. Confirm the exact requirements for your pathway in 32 CFR 170.16, 170.17, or 170.18 and plan the handoff with the responsible reviewer. Keep routine working evidence separate from the final assessment set, with appropriate access controls and retention ownership.
