Domain Aspect Maturity
Conceptual Context & Exchange released

Example

Purpose

The System Context Definition Viewpoint defines on a conceptual level how the SOI is embedded in its environment, i.e., where the boundary of the SOI is and who the external entities are the SOI interacts with (e.g., users, other external systems, environmental conditions, etc.). In addition, the System Context Definition Viewpoint serves as architecture concept to demonstrate how the architecture description defined in the Operational Context Definition Viewpoint is realized.

Applicability

The System Context Definition Viewpoint supports the “prepare for system requirement definition” activity included in the “System Requirements Definition Process” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§2.3.5.3] and contributes to the artifact “System Requirements Definition Report”.
