Which of the following provides a concise, unambiguous, and consistent method for documenting system requirements in software development process ?
Answer: D
The answer is Formal methods.
Formal methods specify system requirements in a mathematical notation (such as Z or VDM), which gives a concise, unambiguous and consistent description that can be checked for contradictions and even used to prove properties of the design.
CMM is a model of process maturity, ISO standards define quality management processes, and CASE tools support development activities. None of these is itself a precise notation for documenting requirements.
