P8_PLOM Physical Logical Mapping Viewpoint
| Domain | Aspect | Maturity |
|---|---|---|
| Physical | Traceability & Mapping |  released |
Purpose
The Physical Logical Mapping Viewpoint supports the definition of the assignment of conceptual logical system elements to physical system elements comprising the SOI.
Following the identification of physical system elements capable of performing the system functions of logical elements, the Physical Logical Mapping Viewpoint provides feedback to the System Architecture Definition process to consolidate or confirm the allocation, partitioning, and alignment of logical elements to physical elements that comprise the SOI.
Applicability
The Physical Logical Mapping Viewpoint supports the “Design Definition Process” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§2.3.5.5] and contributes to the artifact “Traceability Mapping”.
Furthermore, the Physical Logical Mapping Viewpoint supports the “Allocation and Partitioning of Logical Entities to Physical Entities” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2015 [§4.4.2.7].
