They give a big-picture view of the actors in a system, their functions and the interaction of those functions. swimlanes represent departments in the organization.

Use Case Diagram Guidelines. Activity diagram is a special case of a statechart diagram in which all or Guard conditions are used to show that one of a set of concurrent threads is UML Use Case Diagram Symbols. If you want to represent a flow in response to external events instead, use a state machine diagram. A use case diagram helps to model the system and user interactions while an activity diagram helps to model the workflow … Experts recommend that use case diagrams be used to supplement a more descriptive textual use case. 13.

It consists of a sequence of activities that together produce something for the actor. What comes first, the activity diagram or the textual description of the Activity diagram. These include naming standards, directions of arrows, the placing of use cases, usage of system boxes and also proper usage of relationships. Use case analysis usually starts by drawing use case diagrams. An Activity in the activity diagram is also known as Activity state. Start/End: Use a black or solid circle to show where the diagram starts, and a solid circle with a ring around it to indicate the end of the process. The main purpose of the use case specification is to specify any pre-conditions that must be met in order to start the use case, specify any business rules related to the use case steps, and specify any post-conditions that will be present after executing the use case. Activity diagrams present a number of benefits to users. The following figure depicts the same scenario represented in the Activity diagram.
