===== 12.2 Non-Functional Assurance =====
[[fxdemo:07-part:12-architectural-principles:start|Go up to Architectural Principles]]

Non-Functional Assurance is the market condition in which a participant or Node demonstrates that it satisfies the Non-Functional Characteristics that apply to a governed function, governed work assignment, Qualification Profile, policy obligation, evidence obligation, jurisdictional constraint, residency constraint, sovereignty constraint, and market integrity rule.

Non-Functional Assurance establishes that work assignment depends on recognised non-functional capability, measured [[dido:99_annexes:annex-b-terms-and-definitions:p:performance]], [[dido:99_annexes:annex-b-terms-and-definitions:r:reliability]], [[dido:99_annexes:annex-b-terms-and-definitions:m:maintainability]], [[dido:99_annexes:annex-b-terms-and-definitions:s:securability]], [[dido:99_annexes:annex-b-terms-and-definitions:m:manageability]], [[dido:99_annexes:annex-b-terms-and-definitions:u:usability]], [[dido:99_annexes:annex-b-terms-and-definitions:i:interoperability]], [[dido:99_annexes:annex-b-terms-and-definitions:e:elasticity]], evidence production, and continued conformity with applicable qualification requirements.

A participant does not receive governed work merely by asserting non-functional capability. A Node does not receive governed work merely because it connects to the technical environment or advertises a capability. The market recognises non-functional assurance through Qualification Evidence, Monitoring Evidence, Audit Evidence, Policy Evidence, and Selection Criteria that support the assignment.

Non-Functional Assurance protects [[dido:99_annexes:annex-b-terms-and-definitions:b:buyer| Buyers]], [[dido:99_annexes:annex-b-terms-and-definitions:i:integrator| Integrators]], [[dido:99_annexes:annex-b-terms-and-definitions:r:regulator| Regulators]], [[dido:99_annexes:annex-b-terms-and-definitions:a:auditor| Auditors]], [[dido:99_annexes:annex-b-terms-and-definitions:g:governance_body| Governance Bodies]], [[dido:99_annexes:annex-b-terms-and-definitions:q:qualified_service_provider| Qualified Service Providers]], and [[dido:99_annexes:annex-b-terms-and-definitions:q:qualified_node| Qualified Nodes]] by preventing participants or Nodes with inadequate, expired, unverified, degraded, suspended, or non-conforming non-functional capability from receiving governed work.

==== Requirement ====

The Governed Node Service Market SHALL assign governed work only to participants and Nodes that satisfy the Non-Functional Characteristics and the assurance evidence requirements applicable to the governed function.

==== Example ====

A Node connects to the market and advertises semantic validation capability. The market does not assign FX validation work to the Node until the applicable Qualification Profile, Qualification Evidence, Non-Functional Characteristics, monitoring evidence, policy constraints, evidence obligations, jurisdictional constraints, and market rules recognise the Node as eligible for that governed function.
