What is the primary purpose of a Requirements Diagram?

The primary purpose of a Requirements Diagram is to visualize and organize requirements. This type of diagram serves as a crucial tool in systems modeling as it helps stakeholders understand the various requirements of a system in a structured manner. By using visual representations, it becomes easier to identify the relationships and dependencies among requirements, ensuring that all necessary specifications are captured and understood.

Requirements diagrams facilitate communication among team members and stakeholders, allowing for a clearer discussion about what the system needs to achieve. This organization of requirements can support the overall development process, ensuring that all aspects are considered and that nothing is overlooked. The diagram provides a holistic view, making it easier to manage changes or new requirements as they arise throughout the project lifecycle.

The other options focus on aspects such as timelines, stakeholder roles, and budgeting, which do not align with the specific function of a Requirements Diagram. These areas are typically covered by other project management tools and diagrams tailored for those purposes, but they do not address the key intention of organizing and visualizing requirements specifically.
