Use Case

A Use Case in a Use Case Diagram represents a specific action or functionality that the system provides to its users. It describes a sequence of actions that provide a measurable value to an actor.

With Use Cases in Modeldraw's Use Case Diagram, you can:

• Define and illustrate the main functions or services that your system provides

• Capture the interactions between the system and its users (actors)

• Describe the system's behavior from an external user's perspective

• Organize and prioritize system requirements

• Provide a foundation for further detailed analysis, such as creating user stories or functional specifications

• Communicate system functionality to both technical and non-technical stakeholders

Understanding Use Case

A Use Case in Modeldraw's Use Case Diagram tool is typically represented by an oval shape with the name of the use case inside. Use Cases are fundamental components of Use Case Diagrams as they define the system's behavior. Key points to understand about Use Cases include:

• Each Use Case represents a distinct functionality or service that the system offers to its users.

• Use Cases are always associated with one or more Actors who initiate or participate in the functionality.

• Each Use Case should represent a complete and meaningful goal from the user's perspective.

• Use Cases can be high-level (representing major functionality) or more detailed (representing specific operations).

• Use Cases can have relationships with other Use Cases, such as "include" or "extend" relationships.

• Use Cases are typically contained within the system boundary, representing internal system functionality.

Remember that Use Cases should represent distinct, valuable functionalities that your system provides to its users. When naming Use Cases, use clear, action-oriented phrases that describe what the system does from the user's perspective.
