An iterative approach for global requirements elicitation: A case study analysis

Requirements Elicitation phase in Requirements Engineering (RE) is found to be very complex and demands more attention when software development is performed on the global scale. The available approaches of requirements elicitation require vigilant application in different scenarios of GSD and may need further improvement when considering challenges of distributed development. In this paper, a comprehensive survey of requirements elicitation approaches and challenges is performed which describes the limitations in applying the current elicitation approaches in GSD scenarios. Considering these constraints, an iterative framework for elicitation (IRE) in Requirements engineering is proposed. The case study analysis of the proposed model shows the effectiveness of iterative approach. The results show that IRE approach is more effective in satisfying the customer requirements than existing elicitation approaches.
