Vendor AI Due Diligence

A structured assessment of an AI vendor across EU AI Act value-chain obligations, data protection, model risk, security and DORA overlap. Every score is re-performable: the methodology, weights and per-question points are disclosed on screen and in every export.

Scoring methodology & weights

The scoring is deliberately simple so that it can be independently re-performed in Excel from the CSV export, which carries points, maxima and weights for every line.

1 · Answer scale

AnswerPointsTreatment
Yes2Requirement met with evidence.
Partial1Partially met, or met without adequate evidence.
No0Not met. Listed as a gap.
Unsure0Scored as 0 on prudential grounds and flagged for follow-up.
N/AExcluded from both numerator and denominator.

2 · Formulas

Section score = 100 × Σ points ÷ (2 × applicable questions)

Overall score = Σ (section score × weight) ÷ Σ weights of applicable sections

Sections hidden by your scoping answers (e.g. DORA when you are not a financial entity) are excluded entirely and the remaining weights are renormalised. Unanswered questions count as applicable with 0 points, so the score starts low and is earned.

3 · Section weights (editable)

Defaults reflect a regulated-financial-sector risk appetite: documentation and data obligations carry the most weight. Adjust to your own appetite — entries are renormalised to 100% and every export records the weights actually used.

4 · Risk tiers & overrides

Overall scoreTier
≥ 80Low residual risk
60 – 79Moderate
40 – 59Elevated
< 40High

Two overrides sit on top of the arithmetic and are reported whenever applied: critical questions (marked ) answered No or Unsure floor the tier at Elevated regardless of score; a use case identified as an Art. 5 prohibited practice sets the outcome to Blocked.
