Use Case Model Anti-Patterns

Use Case anti-patterns are common mistakes I've seen students make.

Snow Jobs

Use this anti-pattern if you want to intimidate potential critics with lots of technical jargon:

Bad Actors

Making the subject an actor

Lazy Use Cases

Confusing Extends with Generalization

Use case diagram as a workflow

Internal objects as actors or use cases

Confusing goals with UI triggers

Bad/Inconsistent Language

Scenarios as Use Cases
