C2_SSTD System Structure Definition Viewpoint
| Domain | Aspect | Maturity |
|---|---|---|
| Conceptual | Taxonomy & Structure |  released |
Purpose
The System Structure Definition Viewpoint describes how the system is decomposed into a hierarchical structure of conceptual elements. These conceptual system parts will be used to assign responsibilty to functions to them (divide & conquer principle). It covers related concepts and principles that define what the system does and is widely reusable among similar systems like product families, or product generations.
Applicability
The System Structure Viewpoint supports the “System Architecture Definition Process” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§2.3.5.4] and contributes to the artifact “System Architecture Description”.
Furthermore, the System Structure Viewpoint supports the “Allocation and Partitioning of System Functions to Logical Entities” activities, by providing the structure to allocate functions to.

Presentation
A block definition diagram (BDD) featuring the conceptual system block and conceptual system blocks for parts of the system. These elements are connected to the system block by means of aggregation relationships. Note: Multiple relationships to a kind of element are allowed. This means, that this kind of element is used in several roles.

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 Internal Role | Specifies the fact that a Conceptual System may consist of Conceptual Systems (a white box perspective on a conceptual system). |
| 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. |
