Software requirements

This research paper provides software life cycle models and compares their performance. In a software industry every day a new SDLC model introduced but each model have some merits and demerits. So none of them fulfill all customer requirements. In software industry more than 50% software never use and more than 70% software not satisfies user requirements. In this paper we compare software life cycle models and try to identify which model is useful for which customer. So as per requirement developer selects one model and try to satisfy customer requirements.
