A Collaborative Effort-Benefit-Value Analysis Model to Support Requirements Reuse for Software Requirements Prioritization

Abstract

This paper proposes a collaborative method to prioritize the set of requirements backing the concept of requirement re usability through crowd sourcing platform. Both stakeholder and developer perspectives are captured and effort-benefit-value analysis model is presented. Stakeholder priority is captured using Fuzzy TOPSIS model, and developer priority is captured by analyzing inter-relationships among requirements in the form of dependency. Further, a provision is provided to resolve conflicts between requirement pairs in an interactive manner to produce final ranking accepted to both with minimum conflict. An experimental proof of concept is provided by comparing results of proposed approach with state of art, fuzzy analytic hierarchy process (FAHP), interactive genetic algorithm (IGA) techniques, and on a dataset. Results of experimentation conclude that presented approach is capable of producing accurate and comparable results in addition to handling issue of dependency, multi- criteria preferences, reliability, and robustness to errors.
