===== Statement =====

Logical [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] SHALL NOT require artificial one-to-one correspondence where one-to-many or many-to-one relationships better represent the architecture.

===== Source =====

Part 2, Section 16.9: Logical Traceability Requirements.

===== Rationale =====

Architectural relationships are not always one-to-one. A single conceptual concern may refine into several logical elements, and multiple logical elements may contribute to a common implementation or evidence artifact. Allowing many-to-one and one-to-many relationships ensures that the Traceability Model accurately reflects the architecture rather than forcing artificial mappings that obscure architectural intent.

===== Applies To =====

This requirement applies to the Logical Traceability Model.

It applies specifically to:

  * Traceability relationships;
  * Conceptual elements;
  * Logical elements;
  * Domain Logical Profiles; and
  * Implementation Profiles.

===== Verification =====

Verification SHALL confirm that the Logical Traceability Model supports the architectural relationships actually present.

Verification activities should include review checks confirming that:

  * one-to-many relationships are permitted where appropriate;
  * many-to-one relationships are permitted where appropriate;
  * artificial mappings are avoided; and
  * traceability accurately represents the architecture.

===== Traceability =====

This requirement supports accurate traceability throughout the architecture lifecycle without imposing unnecessary structural constraints.
