Conformance Criterion

Go up to Terms and Definitions

Discussion

A Conformance Criterion establishes an assessable condition used to determine whether an identified subject satisfies an applicable Requirement and therefore achieves Conformance.

A Conformance Criterion translates a normative Requirement into an observable and assessable condition without changing the meaning or scope of the Requirement.

A Conformance Criterion provides the basis for evaluating Evidence and supports objective, repeatable, and comparable conformance assessments.

A Conformance Criterion forms part of a Conformance Model.

Definition

assessable condition used to determine satisfaction of a specified requirement

Source

, Section 6.4.6, Implementation Conformance Model

Note

A Conformance Criterion differs from a Requirement.

A Requirement states an obligation.

A Conformance Criterion establishes the assessable condition used to determine whether the obligation has been satisfied.

A Conformance Criterion also differs from a Conformance Point.

A Conformance Criterion defines what an evaluator assesses.

A Conformance Point identifies where an evaluator performs or observes the assessment.

A Conformance Criterion should not introduce an obligation that does not exist in the governing Requirement.

Example

For a Requirement stating that a DIDO-TE implementation preserves Evidence, the associated Conformance Criterion identifies the observable condition used to determine whether the required Evidence has been preserved.
