
Supports IT system, software, and business processes

Models, designs, builds, and tests software

Uses standard Unified Modeling Language (UML)

EA Weaknesses

May be a poor choice for complex system
diagrams
 Visio is “prettier”
 PowerPoint also an option

Complex User Interface
 Extensive feature set may lead to confusion
 Time saving “tricks” difficult to learn

Diagrams not useful if team doesn’t see value
 UML/BPM may be used currently at their site
 Some users intimidated by tool
