Introduction to Use Case Modeling

• Brief background and context for use cases
• Use case definitions, elements, and components
• Benefits of use case modeling
  • Organizing requirements with use cases
  • Use case diagrams as a UML notation
  • Organizing the model with packages

Use case actors

• Users and Actors
• Business and system actors
• Identifying actors and mapping stakeholders

Use Cases - Indentify and Describe

• Identifying use cases and writing description
• Use Case Controls:
  • preconditions
  • postconditions
  • assumptions
  • scenarios

Use Case Scenarios

• Main success scenario
• Alternates and exceptions
• Indicating iteration

Advanced Techniques

• <<include>> relationship
• <<exclude>> relationship
• Generalization
• Specialization
• Multiplicity

Practical Use Cases Concepts

• Flows of events and their purpose: primary, alternate, and exception paths
• Methods for documenting primary flows
• Documenting alternate and exception flows
• Documenting scenarios
• Narrative flow examples
• Use Cases and Test Cases
  • Relationship between use cases and test cases/scenarios
  • Translating use cases into test cases
  • Use cases and user interfaces/prototyping
  • Prototyping roles, preparation, and execution
• UML Concepts
  • UML notation
  • Class and object relationships
  • Extracting classes from use cases
  • Verifying a class: attributes, operations, and associations/multiplicity
  • Include relationship and example
  • Referring to includes in flows
  • Extend relationship and example
  • Referring to extends in flows
  • Generalization relationship and example
• Use case documentation
