Which of the following provides a concise, unambiguous, and consistent method for documenting system requirements in software development process ?

  • A.CMM
  • B.ISO standard
  • C.CASE tools
  • D.Formal methods

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.
