Abstract : Requirements symbolise the need or the set of needs for triggering the development process of the system. The system developed must follow the law of the requirements. Capturing the requirements of a system is a challenge. It is both subjective and objective process. The realistic and comprehensive requirements should be evolved as early as possible during the development cycle of the system. Many a times, it may not be possible to freeze the requirements in a single cycle. This may require a number of iterations. A template has been evolved for speeding up the capturing process of requirements. Requirements analysis spiral(RAS) developed helps in evolving the requirements. The development of the system or the product cannot wait till the requirements have matured, and further, it is also an evolving process. Therefore, continual models of the system have to be developed for achieving the maturity of the system. RAS can be used to freeze the requirements for the initial model and the subsequent models till the maturity of the system is achieved, both in terms of requirements and quality. The paper illustrates the application of RAS for evolving the frozen and matured requirements through a case study.
