What does the requirements architecture illustrate?

The requirements architecture provides a visual representation of how different requirements interrelate within a project. It helps stakeholders understand the connections, dependencies, and hierarchies among requirements, illustrating how one requirement influences another and how they collectively contribute to meeting the overall business objectives. By mapping out these interrelationships, the architecture aids in ensuring comprehensive coverage of needs, avoiding conflicts, and facilitating clearer communication among team members, thereby enhancing requirements analysis and prioritization efforts.

In contrast, project timelines, resource allocation, and cost analysis focus on different dimensions of project management and do not specifically address the organization and connection of requirements. These elements are crucial for overall project success, but they do not provide insight into how requirements interact with one another, which is the core function of requirements architecture.
