What a proof gap is

A proof gap means evidence is missing, weak, unclear, confidential or not obviously connected to the capability being offered. It is not a verdict that the provider is bad.

Common proof gaps

• The profile names an outcome but does not show a comparable example.
• The example is relevant but the provider's own role is unclear.
• The proof is confidential and needs an anonymised alternative.
• The buyer needs sector, system, scale or timeline evidence that is not yet visible.

How buyers should use gaps

Turn proof gaps into better questions: what can be shared, what was similar, what was different, what did the provider personally do, and what risk remains?

How providers can close gaps

Add anonymised case notes, before-and-after examples, screenshots with sensitive data removed, references, metrics or a clear explanation of what cannot be disclosed.
