Source
What the vendor, an independent party, or an internal stakeholder supplied.
Trust & method
Separate evidence from judgment
A useful vendor review shows how a conclusion was reached without presenting a checklist, score, or document as certainty.
What evidence-linked vendor evaluation means
Evidence-linked vendor evaluation keeps each source, vendor claim, reviewer finding, unresolved gap, proposed control, and final decision distinct. The record should show what supports a conclusion, what remains uncertain, and who owns the judgment.
- Intended roles:
- Anyone preparing, reviewing, challenging, or approving an AI vendor decision record.
- Use it when:
- Review notes are fragmented, a score hides context, evidence has mixed scope or age, or multiple functions need to retrace the same decision.
- Inputs:
- Source materials, specific claims, use-case context, reviewer observations, assumptions, evidence limits, open questions, and decision ownership.
- Outputs:
- A traceable evidence chain, bounded findings, visible uncertainty, assigned follow-ups, and a human-owned decision rationale.
- Boundary:
- A traceable method improves inspectability; it does not make the evidence complete, prove a vendor safe or compliant, or replace specialist judgment.
About this resource
AI Vendor Decision publishes static informational resources for structuring an internal vendor review. The site does not receive documents, assess vendors, provide professional advice, or make approval decisions. Check each resource against your current use case, evidence, policies, contracts, and applicable requirements.
The evidence chain
Claim
The specific statement the source is being used to support.
Finding
The reviewer’s bounded interpretation, including limits and uncertainty.
Decision
The accountable person’s conclusion, conditions, and follow-up plan.
Working principles
Make uncertainty inspectable
Scope before scoring
Define the use case and impact before deciding which questions matter.
Original questions
Adapt prompts to the actual workflow rather than assuming one questionnaire fits every vendor.
Evidence with boundaries
Record what an item covers, when it was produced, and what it cannot establish.
Visible gaps
Do not convert missing information into a favorable assumption.
Human ownership
Keep recommendation, risk acceptance, and ongoing oversight assigned to people.
A practical test
Could another reviewer retrace the reasoning?
If the record does not connect material conclusions to evidence, assumptions, and ownership, it is not yet ready for a consequential decision.
Frequently asked questions
What does evidence-linked AI vendor evaluation mean?
It means connecting each material finding to a defined source or marking it as an assumption or open gap. Claims, evidence, reviewer interpretation, and the final decision remain separate.
How should missing evidence be handled?
Record what is missing, why it matters, who owns the follow-up, and whether a narrower use, control, condition, or later review could address the gap. Do not convert missing information into a favorable assumption.
Does this methodology replace specialist review?
No. It structures a review record but does not replace legal, security, privacy, procurement, compliance, or other qualified specialist input when that input is needed.
