Example
Purpose
The P4_PITI Physical Internal Interaction Viewpoint supports the specification of sequences of interactions between physical systems within the system boundary through physical connections. It captures interaction behaviour that is relevant to the physical realization of the system, particularly where it results from physical or technical architectural decisions, such as initialization, handshaking, synchronization, startup, shutdown or recovery. The viewpoint uses the physical structure defined in the P2_PSTD Physical Structure Definition Viewpoint.
Applicability
The P4_PITI Physical Internal Interaction Viewpoint supports the “create system design” activity part of the “Design Definition Process” activities of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§2.3.5.5] and contributes to the artifacts “System Design Description” and “System Interface Definition”.
Furthermore, the viewpoint supports the “Interface Management” approach of the INCOSE SYSTEMS ENGINEERING HANDBOOK 2023 [§3.2.4].
Presentation
The P4_PITI Physical Internal Interaction Viewpoint is presented as a sequence diagram showing exchanges between physical systems within the system boundary through physical connections.
The sequence may represent ordering, timing, duration, periodicity, synchronization and temporal constraints of exchanges.
