Equivalent in nature to L4 - Logical Activities and R4 - Resource Functions, it specifies a set of functions that a service implementation is expected to perform.
Implementation
The S4 view can be represented using:
- S4 Service Functions Taxonomy diagram based on the UML Clas diagram.
- S4 Service Functions diagram for the Operational Activity flows. This diagram is based on the UML Activity diagram.
- UML Activity diagram.
- SysML Activity diagram.
- SysML Block Definition diagram.
