How does a Package Diagram contribute to understanding a system model?

A Package Diagram plays a crucial role in understanding a system model by visually representing the relationships and dependencies between different components of the model. It organizes elements into packages, allowing for a hierarchical view that can help identify how various parts of the system relate to one another. This organization aids in managing complexity and enhances comprehension by showing how packages are interconnected, thereby providing insights into the overall structure of the system.

This emphasis on relationships and dependencies is essential for stakeholders looking to understand how various components interact, influence one another, and contribute to the system's functionality. In contrast to other diagrams that may focus on specific processes or emphasize flow, the Package Diagram's primary function revolves around illustrating these critical connections within the system architecture.
