Return to Requirements

Statement

The Logical Architecture / PIM SHALL organise the architecture around identifiable Logical Nodes.

Source

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

Rationale

Logical Nodes provide the primary organising concept for the Logical Architecture. Identifiable Logical Nodes establish clear responsibilities, communication relationships, governance boundaries, traceability, and reviewability while remaining independent of implementation technology.

Applies To

This requirement applies to the Logical Architecture / PIM and all Domain Logical Profiles that specialise it.

It applies specifically to:

Logical architectural modelling;Identification of Logical Nodes;Assignment of logical responsibilities; andLogical interaction modelling.

Verification

Verification SHALL confirm that the Logical Architecture is organised around identifiable Logical Nodes.

Verification activities should include review checks confirming that:

Logical Nodes are explicitly identified;logical interactions occur among Logical Nodes;logical responsibilities are assigned to Logical Nodes; andthe architecture consistently uses Logical Nodes as the primary organisational element.

Traceability

This requirement supports traceability from conceptual Nodes defined in Part 1 to Logical Nodes defined in Part 2.
