[[dido:99_annexes:annex-d-requirements:part-02:start| Return to Requirements]]

===== Statement =====

The Logical Traceability Model SHALL define [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] from Part 1 conceptual elements to Part 2 logical elements.

===== Source =====

Part 2, Section 16.9: Logical Traceability Requirements.

===== Rationale =====

The Logical Architecture refines, but does not replace, the Part 1 Conceptual Architecture. Explicit traceability preserves the relationship between conceptual intent and logical realization, supporting governance, review, impact analysis, and long-term architectural evolution.

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

This requirement applies to the Logical Traceability Model.

It applies specifically to:

  * Part 1 Conceptual Architecture;
  * Part 2 Logical Architecture;
  * Conceptual elements; and
  * Logical elements.

===== Verification =====

Verification SHALL confirm that the Logical Traceability Model defines traceability from Part 1 conceptual elements to Part 2 logical elements.

Verification activities should include review checks confirming that:

  * conceptual sources are identified;
  * logical elements trace to their conceptual origins;
  * traceability supports architectural review; and
  * conceptual meaning is preserved.

===== Traceability =====

This requirement supports traceability between conceptual architecture and logical architecture.
