I am supporting a system engineer to model the behavior of a sub-system and, while defining a scenario I came up to a problem which was: how to depict continuous and event-driven dynamics?
The Architecture diagram is not enough since it is static and the event-driven part is not explicit.
In the Sequence diagram (Exchange Scenario) I only found the pattern below to model this behavior. My question is, is this good? Do you have any better ideas to depict this information?
