Popular Sequence Diagram Uses

Just as you might use a UML sequence diagram to explore the logic of a use case, you can use it to explore the logic of any function, procedure, or complex process.
If you consider a service to be a high-level method used by different clients, a sequence diagram is an ideal way to map that out.
