Use case diagram
What is a use case diagram? Use case diagram is a UML diagram with actors (i.e. stick figures) and use cases (i.e. ovals) showing the user goals.
You can visualize high level system functions or requirements by drawing use case diagram, which contains primarily actors and use cases. Actors are entities that interact with the system, while use cases are the system functions actors involve. Note that you draw use case diagram to tell readers WHAT the system should do but not how to do.

Use case and actor grids list use cases and actors in your project in tabular form. With the grid, you can create, read, update and delete use cases and actors. You can also customize the grid to display the element properties you want. The following movie shows you how to operate with such powerful grid.
