A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well.

Note that there are no buttons, controls, forms, or any other UI elements and operations in the basic use case description, where only user goals, subgoals, or intentions are expressed in every step of the basic flow or extensions.
Automated workflow analysis techniques can help users analyze the properties of user workflows to conduct verification of certain properties before executing them, e.g., analyzing flow control or data flow. Examples of tools based on formal analysis frameworks have been developed and used for the analysis of scientific workflows and can be ...
