Use Case Diagrams
Who is outside the system, what do they want, and what crosses the boundary?
THAPAR / UCS503
Software Engineering
Carry one familiar system through five connected diagrams, and defend every element you draw.
WHAT YOU SHOULD BE ABLE TO DEFEND
- Fix the system boundary before drawing.
- Carry one scenario across several UML views.
- Explain why every actor, message, class, decision and lane exists.
COURSE MAP
