Use Case Realization Model

In UP, a Use Case Realization describes how the behavior of a Use Case is realized by collaborating Model elements in a Design Model. A Use Case Realization Model represents the mappings between a Use Case Scenario and the participants, responsibilities, Interactions, Operations, and Outcomes that realize it.

SimpleModeling treats it as the reviewable intermediate Model at the center of Application Modeling. Starting from a natural-language Use Case Scenario, a Collaboration describes participants, Roles, and responsibilities, while an Interaction provides a concrete execution example; these are mapped to Services and Operations, Events, StateMachines, and related elements. AI proposes the mappings and people approve their meaning and correspondence. CBD Support assists with evidence, differences, Traceability, and conformance to execution examples, and a skill applies approved changes to CML. Review records remain separate from the Model itself.
