Use-Cases A description of system behavior, in terms of sequences of actions. A use case should yield an observable result of value to an actor. A use case contains all flows of events related to producing the "observable result of value", including alternate and exception flows. More formally, a use case defines a set of use-case instances or scenarios.actoruse-case instances scenarios The specification of a sequence of actions, including variants, that a system (or other entity) can perform, interacting with actors of the system.actors

Use-Cases Business Use-Case A sequence of actions performed by a business that yields an observable result of value to a particular business actor.

Use-Cases Right Click new diagram Select Rename Paste use-case name and add “Detail”

Activity Diagrams (AD) Definition: Defines the workflow associated with the use case How used Details the actions to be taken and decisions to be made for a use case Helps identify possible use cases at next level of detail Types Regular With Swimlanes With State Transitions

Activity Diagram Symbols Start State End State Activity Decision State Transition Regular Transition To Self Horizontal and Vertical Synchronization

Activity Diagram Symbols Swimlane State Note Note Anchor Text

Analysis Steps For each identified use case Create a context and detail activity diagram Identify potential sub-use cases Create a new package, use case, and related diagrams for the identified sub- use case Move relevant activities under the sub- use case
