Flexible CASE Tools for Requirements Engineering: A benchmarking Survey

Requirements engineering (RE) is a vital component in successful project development. Studies show that up-front attention to requirements can save the economy billions of dollars, yet RE concerns are often treated as an afterthought to user requirements. Industry can thus benefit from a model to examine requirements in the development stages of the production life cycle. Choosing an appropriate CASE tool to perform RE tasks became an increasingly harder, due to the tremendous number of CASE tools in this field. This paper introduces a survey of some of these tools available in the software market, comparing them to allow the reader to reach an adequate decision about which tool to use relative to his needs and software system circumstances
