Requirement guide Evidence readiness
What evidence can be reused across assessments and customer requests?
Evidence is most reusable when the team can show what it demonstrates, which environment it covers, who owns it, when it was reviewed, and which requirement or claim it supports. The next reviewer can then evaluate the difference between the existing evidence and the new request.

What to confirm
A new customer’s terms, a changed system boundary, or an assessor’s request for direct demonstration can require additional evidence.
Organize the requirement, work, and evidence.
Deep Fathom records the source requirement, accountable owner, assigned work, supporting evidence, and review history. The team can then review the specific requirement instead of searching across disconnected documents.
