[[dido:99_annexes:annex-d-requirements:part-01:start|Return to Part 1 Requirements]]

===== Statement =====

The [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Architecture]] / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|PIM]] SHALL provide [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] from logical elements to the conceptual elements they specialize, refine, constrain, or relate.

===== Source =====

Part 1, Section 13.9: Relationship to Logical Architecture / PIM Requirements.

===== Rationale =====

Traceability from logical elements to conceptual elements preserves the connection between conceptual meaning and logical refinement. It allows reviewers to confirm that each logical element has a conceptual basis and that logical refinement does not change conceptual meaning.

This requirement supports forward review, backward review, impact analysis, and controlled evolution between Part 1 and the Logical Architecture / PIM.

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

This requirement applies to Logical Architecture / PIM traceability relationships.

It applies specifically to logical elements that:

  * Specialize conceptual elements
  * Refine conceptual elements
  * Constrain conceptual elements
  * Relate to conceptual elements
  * Support conceptual-to-logical review

===== Verification =====

Verification SHALL confirm that the Logical Architecture / PIM provides Traceability from logical elements to the conceptual elements they specialize, refine, constrain, or relate.

Verification activities include review checks confirming that:

  * Logical elements identify related conceptual elements
  * Trace links describe specialization, refinement, constraint, or relationship
  * Trace links support review from logical elements back to conceptual elements
  * Trace links support impact analysis between conceptual and logical material
