Example
Purpose
The System Internal Exchange Viewpoint serves for the identification and definition of interfaces of elements of the conceptual system. also, the delegation of system element interfaces to the conceptual system boundary interfaces is covered. The System Internal Exchange Viewpoint
- identifies system element interfaces on a conceptual level
- states to which other conceptual elements the interfaces are connected to
- assigns conceptual interface definitions to interfaces
- defines the usage of interfaces, e.g., if only a subset of the interfaces is used
- defines the delegation of conceptual system element interfaces to the conceptual system boundary interfaces
Applicability
The Conceptual Internal Exchange Viewpoint supports the “System Architecture Definition Process” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§2.3.5.4] and contributes to the artifacts “System Architecture Description” and “System Interface Definition”.
Presentation
One or more IBDs featuring the SOI boundary, the conceptual elements of the SOI, as well as the connectors for each identified SOI interface delegation to conceptual SOI elements. An interface is a connection resource for hooking on the conceptual SOI elements to other conceptual SOI elements. Item flows are defined for each exchange on the identified interface. Note: Please use more than one IBD focused on different areas of interest to keep the view comprehensive.
Stakeholder
Concern
- How do the conceptual system elements interact to provide the system functions?
- What are the items exchanged between conceptual system elements during an interaction?
- Which conceptual items (energy, material, information, etc.) are exchanged within the system?
- Which requirements apply to a coinceptual interface?
