Full definition
Minimum viable evidence is defined as: Minimum viable evidence is the smallest set of documents that genuinely answers the question a client, auditor or regulator is asking - no more, no less.
The failure mode this fixes is evidence bloat: asking suppliers for everything just in case, then not reading most of it. Minimum viable evidence forces a specific question first (what could go wrong here, what would prove it will not) and then a specific document list.
The practical output is a shorter checklist per supplier type, faster onboarding and higher signal per document.
