Purification of requirement engineering model for rapid application development

Due to shortage of time, most of the software organizations are shifting their projects to rapid application development's life cycle. But main problem is that rate of projects failure is increasing day by day. According to Standish group report, success rate of projects is only 16.2%. The main reason of project's failure is poor requirement engineering. The main objective of carried research is to purpose a model for requirement engineering process of rapid application development. The proposed model has 7 steps. Our proposed model specifies techniques for each step of requirement engineering process. Our proposed model also introduces new stages of conflict management by win-win approach and requirement prioritization by card sorting in requirement engineering model for rapid application development's life cycle. Validation of purposed model has been done by survey from 50 experienced software professionals of 20 different organizations. Survey proved that our purposed model has more customer's favor then traditional requirement engineering model for rapid application development. Our proposed model is fully customer's oriented. It is more time effective, cost effective, well managed and efficient than traditional model.
