Requirement Negotiation Methods in Requirements Engineering
Main Article Content
Abstract
Requirements engineering is a fundamental part of the software engineering process. When the stakeholders of the software project disagree on the requirements, requirements negotiation methods can be used to reach that agreement. This avoids rework and extra costs. A number of new requirements negotiation methods are created by researchers over the last years. This paper provides a review on which negotiation method can be used under which circumstances. Such a review is relevant for both practitioners and researchers. Practitioners could use the results to make decisions on which method might be the best choice for their project contexts. To researchers, it would help them see trends in the requirements negotiation field. In this paper more attention is given to create new requirements negotiation methods than before and the methods also cover more types of requirement conflicts now than they did in the past. We also found that requirements contradiction conflicts and quality attribute conflicts are getting more attention now than they were getting before, while resource conflicts and feasibility conflicts still are getting almost no attention at all. Furthermore, we found that almost all requirements negotiation methods are suitable for resolving viewpoint conflicts. Finally, Theory W (WinWin approach) [2] is still very popular for use in the design of requirements negotiation methods.
