The Use Case Pattern Language
نویسنده
چکیده
Use cases are a wonderfully simple concept, describe a system ́s functional requirements by telling stories about how its usage delivers value to its actors. Yet, for such a simple concept, good use cases are really hard to write. Use case authors frequently must deal with the difficult questions of: •= Where is the system boundary? •= What should the scope of a use case be? •= What is the level of detail I should express in the use case? •= How should I structure the use case description? •= When should I create "include" and "extends" use cases? •= Why am I doing this in the first place?
