Answer 1

Advantage 1: Clarity

-UML enables software designers to present a clear model of a system, such as a game, offering a comprehensive view for the development team.
-Use Case Diagrams in UML highlight crucial system aspects, allowing developers to focus on essential functionalities and avoid distractions.
- It facilitates prioritizing and solving critical issues upfront, ensuring project goals are transparent to all stakeholders.

Advantage 2: Avoiding Scope Creep

Use Case Diagrams define the system boundary, guiding developers to focus only on functionalities within scope for the current version of the system.
