====== P2-REQ-16-2-002 ======

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

===== Statement =====

The Logical Architecture / PIM SHALL define one logical architecture and SHALL NOT imply that it represents every possible logical architecture that conforms to Part 1.

===== Source =====

Part 2, Section 16.2: Distributed Node-Based Architecture Requirements.

===== Rationale =====

Part 2 defines a single reusable Logical Architecture / PIM for the Financial Systems Archetype. Other logical architectures may also conform to the Part 1 Conceptual Architecture, but they are outside the scope of this document set. Stating this explicitly prevents readers from interpreting the architecture defined in Part 2 as the only permissible logical realization.

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

This requirement applies to the definition, review, interpretation, maintenance, and use of the Logical Architecture / PIM.

It applies specifically to:

  * The scope of the Logical Architecture;
  * Architectural interpretation;
  * Domain Logical Profiles derived from Part 2; and
  * Implementation Profiles based upon Part 2.

===== Verification =====

Verification SHALL confirm that Part 2 defines one Logical Architecture / PIM without claiming that it represents every possible logical architecture conforming to Part 1.

Verification activities should include review checks confirming that:

  * only one Logical Architecture is defined within Part 2;
  * alternative logical architectures are not excluded by implication;
  * the document consistently refers to the architecture defined in Part 2; and
  * no normative statements claim exclusivity beyond the scope of this document.

===== Traceability =====

This requirement supports traceability between the Part 1 Conceptual Architecture and the Logical Architecture defined by Part 2.
