Due diligence

Due diligence is the proportionate investigation of a proposed supplier, transaction, or relationship before an authorized decision. The review may cover identity, ownership, financial condition, sanctions, security, privacy, quality, capability, insurance, legal, sustainability, or operational risk, depending on context. Required evidence, reviewers, refresh intervals, and escalation paths should be defined rather than assumed.
