Use Case Modeling Training

This course has been approved for 14 PDUs | 14 CDUs

Major Components of Use Case Models

• Actors: Entities that interact with the system (users, external systems).
• Use Cases: Specific functionalities or services provided by the system.
• Relationships: Connections between actors and use cases, including associations, generalizations, and include/extend relationships.
• System Boundary: Defines the scope of the system and separates it from the external environment.

Types of Actors

• Primary Actors: Directly interact with the system to achieve a goal.
• Secondary Actors: Support the primary actors in achieving their goals.
• External Systems: Other systems that interact with the system being modeled.

Use Case Diagram

Develop a use case diagram to visually represent the interactions between actors and use cases.

Narrative Flow of Events

Utilize a Use Case Template to document the flow of events for each use case, including:

• Preconditions
• Main Flow
• Alternative Flows
• Postconditions

Activity Diagram

Create an Activity Diagram to chart the scenarios of a use case, illustrating the flow of control and data.

Use Case Relationships

Diagram various use case relationships, including:

• Include: A use case that is always called by another use case.
• Extend: A use case that adds optional behavior to another use case.
• Generalization: A hierarchy where a more specific use case inherits behavior from a more general use case.

Leveraging Use Cases

Use cases can be leveraged to quickly create:

• Test Cases
• User Interface Prototypes
