Signal
Supplier due diligence — evidence packs beat narrative (OECD control map)
For procurement and partner onboarding, the fastest way to reduce avoidable rework is an explicit evidence pack mapped to key risk claims (ownership, integrity, resilience), not prose or self-attestation.
Reader guide
How to read this Signal
Evidence → Uncertainty → Trigger → Decision implication
Each Signal separates the sourced change from what remains uncertain, identifies the trigger to watch and states why it matters to a decision.

Key points
What the evidence indicates for the decision.
- →Treat due diligence as a control design problem: define what must be true, what evidence counts, and how often it must be refreshed.
- →Map each onboarding claim to a source class (registry/authority, reputable media, sourced databases, counterparty-provided artefacts) and weight accordingly.
- →Use disqualifiers upfront (e.g., unresolved sanctions exposure, opaque ownership, repeated delivery failures) to stop ‘slow no’ decisions.

Actions
Practical next steps if this Signal touches your mandate.
- 01Adopt a one-page Supplier Evidence Pack: identity anchors; UBO/ownership map; compliance posture; delivery capacity; financial stress indicators; key contracts/clients (where lawful).
- 02Add a refresh cadence by risk tier (e.g., high-risk quarterly; medium bi-annual; low annual) and document exceptions.
