Use Case Specification at Different Levels of Abstraction

Use cases are narrative description of interactions between users and a software system. They are primary used to specify functional system requirements. Despite the fact that use cases are narrative, there is no standard that specifies what textual specification of use case should like. However, the integration of use cases in a Model Driven Engineering process requires more rigorous specifications. The specification of use cases at different levels of abstraction is needed because of the large number of stakeholders involved in the software development process. We propose use cases specification at different levels of abstraction to promote better integration, communication and understanding among the involved stakeholders. We still discuss that base on this approach different software development artifacts such as domain model, system operations, user interface design can be automatically generated or validated.
