In requirements documentation, which statements are true regarding model-based versus natural language?

In requirements documentation, both statements regarding model-based versus natural language are true.

Model-based approaches can indeed provide a higher level of abstraction, allowing for complex systems to be represented in a simplified manner. This simplification helps in reducing complexity effectively, which is one of the significant strengths of using models. By utilizing diagrams, charts, and formal notations, model-based methods can depict relationships and interactions in a way that is clearer and more structured than natural language descriptions.

Additionally, model-based documentation can dispense with the need for extensive use of natural language in many cases. While natural language is foundational and widely understood, it can sometimes lead to ambiguity and misinterpretation. Models can convey information in a more standardized form, which minimizes these issues and aids in consensus-building among stakeholders.

Therefore, the combination of both statements as accurate characterizes the advantages of using a model-based approach in requirements documentation over relying solely on natural language.
