Abstract
In this paper, we propose a probabilistic model for measuring one of the many Non-functional requirements, namely, the Scalability, which is largely unexplored till now early in software development life cycle. The proposed model is a combination of Prototype and Spiral models; those are standard and accepted SDLC models. Developing software which addresses the functional requirements only, can lead to a solution, but quality attributes for that remain unanswered. It may be a less useful, slow, less reliable system. The system’s ‘quality characteristics’ or ‘quality attributes’ are specified in the Non functional requirements to improve QoS which are hardly covered by functional requirements. The proposed model, named Proto-Spiral can be used for measuring many of the non-functional requirements. In this paper it has been used to evaluate scalability parameters of the software. We have used a case study of the website ebay.com, a dominant online store to illustrate our approach.
