A good requirement is necessary, verifiable, and attainable to satisfy stakeholders of weapon systems. It reduce a dominant cause of cost and schedule overrun of the developing system. But one of the fundamental problems associated with writing good requirements is that most engineers are not specifically trained to write requirements. The basics of well defined requirements are clarity, conciseness and simplicity.
This paper presents a structured methodology for measuring the quality of requirements, individually and collectively. It is shown that requirements may be characterized by ten quality factors, each with an associated metric, and by an overall requirements quality metric. In addition, a tool which estimates requirement statements quality quantitatively is presented.
