Principles for credible evidence standards

A credible evidence standard should make the relationship between evidence and a consequential decision clearer over time, across systems and between organisations.

Point-in-time
Evidence should be captured at, or demonstrably applicable to, the execution boundary.
Portable
A record should remain intelligible beyond the originating workflow or interface.
Versioned
The standard, profile and relevant source versions should be identifiable.
Provenance-aware
Sources, issuers, timestamps and integrity details should be declared.
Authority-aware
The role, delegation, limits and approval state behind the act should be visible.
Limitation-aware
Unknowns, exclusions, conflicts and unavailable evidence should remain explicit.
Implementation-neutral
The standard should describe exchange and review requirements without prescribing one product or architecture.
Independently reviewable
A reviewer should be able to assess the declared package without relying solely on an untested assertion.
Decision-linked
Evidence should state its relationship to the specific consequential decision.
Relationship-aware
The record should distinguish available, relied-upon, excluded and superseded evidence.
These principles describe qualities of a useful evidence standard. They do not certify an organisation, implementation or decision outcome.
