Supplier Due Diligence Risk Tiering: How to Avoid One-Size-Fits-All Reviews
Build risk tiers that determine questionnaire depth, evidence requirements, approval thresholds and review frequency.
Guide contents
Tiering should change the workflow
A risk score is useful only if it changes which requirements apply, how often the supplier is reviewed or who must approve an exception.
Use explainable drivers
Supplier category, geography, criticality, product exposure, spend and prior findings are easier to govern than opaque scores with no operational interpretation.
Combine inherent and control evidence
Separate the supplier’s underlying exposure from the evidence showing how risks are managed.
Re-tier on meaningful events
Material sourcing changes, new geographies, findings or regulatory exposure should trigger reassessment instead of waiting for an annual cycle.
