How do you draw a good use case diagram?
How to Draw a Use Case Diagram?
- Identify the Actors (role of users) of the system.
- For each category of users, identify all roles played by the users relevant to the system.
- Identify what are the users required the system to be performed to achieve these goals.
- Create use cases for every goal.
- Structure the use cases.
What is the best way to describe a use case?
A use case is a written description of how users will perform tasks on your website. It outlines, from a user’s point of view, a system’s behavior as it responds to a request. Each use case is represented as a sequence of simple steps, beginning with a user’s goal and ending when that goal is fulfilled.
What are the correct components of a use case diagram?

- System: A specific sequence of actions and interactions between actors and the system.
- Goals: The end result of most use cases.

What are the characteristics of a use case?
A use case (or set of use cases) has these characteristics: 1 Organizes functional requirements 2 Models the goals of system/actor (user) interactions 3 Describes one main flow of events (main scenarios) and possibly other exceptional flows (alternatives), also called paths or user scenarios
