Abstract
Requirements engineering (RE) is considered as one of the most critical phases in the software life-cycle, and poorly implemented RE processes are among the major risks for project failure. Stakeholders are often faced with the challenge that the complexity of information outstrips their capability to survey it and to decide about which requirements should be taken into account. Additionally, preferences regarding a set of requirements are typically not known before-hand but constructed within the scope of a decision making process. In this paper we introduce a simple application scenario and discuss recommendation and decision technologies which can be exploited for proactively supporting stakeholders in their decision making.
