Phase(s)

Drill down use case diagrams

aid in defining functional requirements one module

at a time.

Use case diagramsaid in the analysisand documentationof high level requirements forscope & stakeholders Drill down to

design each module.

Use Case Diagram Format

Ovals depict each use case – a system action.

The System is inside the rectangle

Notes, re: DFDs

Event (use case) names are verb-object like DFD processes

No data stores

Focus is on interaction of Actors (system users) with the system

No arrow heads for lines connecting actor and use case, since considered two-way
