Figure 7-15 SysML interaction diagram
Activity diagrams in SysML provide the ability to represent continuous flow; this
could not be done [as well?] in UML. However, we have found that interaction
diagrams better express the semantics of collaboration. Additionally, we have
found it simpler to extract information automatically from interaction diagrams;
nevertheless, we know that activity diagrams are used extensively by major
practitioners.
