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.
