Verifiability

Verifiability helps assure users that information faithfully represents what it purports to represent because knowledgeable independent observers can reach consensus. Direct verification might involve counting cash; indirect verification might check inputs and recalculate a model. Estimates can be verifiable when observers understand the method and evidence even though they cannot establish one exact outcome. Verification supports faithful representation. Auditors use evidence and judgement; an audit does not certify that every number is exact.
