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?
Exposed Concepts
The Diagram shows the concepts exposed by the viewpoint, and related concepts if necessary.
The Table shows the concepts exposed by the viewpoint, and related concepts if necessary.
| Concept | Documentation |
|---|---|
| Conceptual Item Exchange | Specifies the exchange that is to take place on a connection of two interaction points on Conceptual Level. |
| applyingTo | Specifies the fact that a Conceptual Interaction Point applies to a Conceptual System. |
| Conceptual Interaction Point Definition | Specifies the exchange capabilities of an interaction point on Conceptual Level. |
| Conceptual Interaction Point | Specifies the existence of an interaction point on Conceptual Level. |
| Conceptual Connection | Specifies the connection of two interaction points on Logical Level. Note: Connections between logical components indicate that item flows are passed from one output of a source component to one or more inputs of target components. |
| Conceptual System | Describes a conceptual system as specification for an implementation of a system. It is used in both functional and logical architectures on any hierarchy level. |
| allowing | Specifies the fact that a Conceptual Item Exchange is allowed on the Conceptual Connection. |
| Conceptual Interaction Point Property | Specifies a detail of an interaction point on Logical Level. |
| Conceptual Exchange Type | Specification for any type of conceptual item (energy, material, information, etc.) to be exchanged on Conceptual (Functional Architecture and Logical Architecture) Level. The Conceptual Exchange Type is agnostic to any realization on Physical Level. |
| defining | Specifies the fact that a Conceptual Interaction Point Definition defines the exchange capabilities of a Conceptual Interaction Point. |
| typing | Specifies the fact that a Conceptual Exchange Type defines the type of a Conceptual Interaction Point Property. |
| specifyingDetailOf | Specifies the fact that a Conceptual Interaction Point Property is a detail of a Conceptual Interaction Point Definition. |
| typing | Specifies the fact that a Conceptual Exchange Type defines the type of a Logical Item Exchange. |
