IREB Certified Professional for Requirements Engineering – Foundation Level — Question 11

Requirements documentation can either be natural language or model-based.
Which two statements are most applicable? (Choose two.)

Answer options

• A. If documentation is model-based, natural language documentation can be dispensed with.
• B. As models are more formal, they offer a higher degree of uniqueness compared to natural language.
• C. In requirements engineering models are more suitable than textual descriptions to reduce the complexity of the entity being considered.
• D. When deciding between model-based and natural language documentation, model-based is preferable.

Correct answer: A, B

Explanation

Option A is correct because if a model is comprehensive, it can replace the need for natural language documentation. Option B is also correct as models, being more formal, do indeed provide a higher level of uniqueness. Options C and D, while they may have merit, do not specifically address the primary statements regarding the use of model-based documentation versus natural language in terms of necessity and specificity.
