An approach for decomposing requirements into analysis pattern using problem frames (DRAP-PF)

Requirements engineering is one of the necessary and difficult tasks during software development process. The steps in requirements engineering depends very much on the analysts experience and educations. Here, the process starts from decomposition of the environment using problem frames (PF) approach into problem domains where we can get requirements and it gives a formal requirement phenomenon of the interconnected domains. In each step, the requirement reusability can be helped towards the problem frame where analysis pattern can help to overcome the reconstruction of requirements and provide guidance to the analysts. In such cases for solving each problem frame, appropriate patterns should be retrieved and it is used for providing a solution space to it. Once the requirements are clear then they can be included for requirement progression to derive its specification towards the machine with the help of analysis pattern. The influence of the requirement progression of the whole problem will be analyzed. Finally, the given framework is implemented with a case study using ATL(Atlass Transformation Language). In this paper, we propose a new methodological framework for guiding requirements domain to development with the help of analysis pattern.
