Guiding requirements elicitation using a prioritization framework

In the area of information systems (IS), one major goal of many IS development projects is to support the business processes of an enterprise in order to optimize business performance. In this area, business-process-driven requirements engineering (BPRE) plays an important role, combining business process management activities and requirements engineering (RE) activities. Thereby, decisions have to be made in order to decide which business processes and derived requirements are the most valuable ones and therefore, where effort should reasonably be spent for elicitation and analysis activities. In order to focus on those requirements that promise the greatest value regarding certain criteria, typically prioritization techniques are used. However, most prioritization approaches are too generic to provide an appropriate solution for the BPRE context. Furthermore, they do not support the requirements engineer during elicitation in order to depict those requirements valuable for further analysis and refinement. To tackle this problem, the idea of applying different models during prioritization is applied. This is expected to reduce unnecessary (RE) activities by focusing on the most important requirements. In this paper, we introduce a prioritization method from our BPRE prioritization framework to cope with this problem.
