• Sample steps in use case modeling
• Find a candidate system boundary
• Find actors
• Find use cases
• Specify the use case
• Identify key alternative flows
• Iterate until the use cases, actors, and system
  boundary are stable

Requirements Tracing

• Functional Requirements vs Use Case Models
• One use case may cover many individual functional
  requirements, and one functional requirement may
  manifest in several different use cases
• Using UML tagged values for associating a list of
  requirement ID numbers with each use case.

• Use case models describe functional requirements,
  actors, and interfaces
• Use models models may not be suitable for
  describing systems dominated with non-functional
  requirements
