Handle the interface between the system and its actors (e.g., a LoginForm or API_Gateway ).
These handle the interaction between the system and its actors (users or external systems). Examples include user interface screens, API endpoints, and communication protocols.
Search GitHub for usecase template markdown . You will find dozens of repositories where teams document features exactly as Jacobson described—actors, pre/post conditions, main success scenarios, and extensions.
The OOSE methodology structures the development process around three primary models:
