What type of representation is a requirements model?

A requirements model serves as an abstract graphical representation that helps in the visualization and organization of the requirements for a system or project. By using various graphical techniques, such as diagrams or flowcharts, a requirements model allows stakeholders to understand complex relationships and structures at a higher level, rather than getting bogged down in textual descriptions or extensive detail. This abstraction aids in identifying key elements, interactions, and flows without the clutter of exhaustive specifications.

In contrast, other options lack the core characteristics of a requirements model. Literal textual descriptions typically focus on specific details and wording, which can be limiting in conveying the overall picture. Comprehensive technical specifications provide intricate details about system requirements, yet they may overwhelm stakeholders instead of providing clarity through abstraction. A detailed project plan, on the other hand, outlines timelines, resources, and tasks, which is fundamentally different from the purpose of a requirements model, as it centers around requirements rather than project execution.
