What is the primary purpose of a Package Diagram?

The primary purpose of a Package Diagram is to display the organization of a system model. It serves as a visual representation of the structure of the system by grouping elements into packages, which helps in managing complexity and organizing related components. By illustrating how packages are related and how they interact, this type of diagram aids in understanding the hierarchical nature of a model, making it easier for stakeholders to navigate and comprehend the overall system architecture.

Package Diagrams are especially valuable in large systems where numerous components exist. They emphasize the relationships and dependencies between different packages, which facilitates modular development and maintenance of the system. This organization is crucial for ensuring that system developers can efficiently manage changes and maintain clarity in large-scale projects. Therefore, the focus on organizing elements within a model and clarifying the relationships among those elements solidifies the role of the Package Diagram in system design and modeling efforts.
