Purpose
The Logical Internal Interaction Viewpoint describes System internal behavior based on the exchange between the Logical SOI Elements Usage. It depicts the sequence of interactions between the Logical SOI Elements and the exchanged Domain Item Kinds needed to accomplish a System Partial Function.
Applicability
The Logical Internal Interaction Viewpoint supports the activities of the System Architecture Definition Process” of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§2.3.5.4] and contributes to the System Architecture description.

Presentation
A sequence diagram featuring the flow of control between Internal Logical Elements of the SOI. Note: This diagram depicts the sending and receiving of messages between the interacting entities called lifelines where time is represented along the vertical axis. The lifeline representatives are part properties typed by Logical System Elements.
