Use Case Modeling

Use Case Modeling is the activity of constructing a Use Case Model of user and external-party intent toward a system using Actors, Goals, Use Cases, Scenarios, and Outcomes.

SimpleModeling positions Use Case Modeling as an activity that constructs a purpose-specific applied Model from Object, Knowledge, and Literate Models. A natural-language Use Case Scenario is one kind of Literate Model, but the Literate Model is not limited to Use Case Scenarios.

Use Case Modeling clarifies user Goals, Scenarios, and expected Outcomes. Application Modeling concretizes how the application realizes those Use Cases through Use Case Realization Models, Collaborations, Interactions, StateMachines, Events, Services, and Operations.
