  Requirements Engineering in open source projects such as Eclipse faces the
challenge of having to prioritize requirements for individual contributors in a
more or less unobtrusive fashion. In contrast to conventional industrial
software development projects, contributors in open source platforms can decide
on their own which requirements to implement next. In this context, the main
role of prioritization is to support contributors in figuring out the most
relevant and interesting requirements to be implemented next and thus avoid
time-consuming and inefficient search processes. In this paper, we show how
utility-based prioritization approaches can be used to support contributors in
conventional as well as in open source Requirements Engineering scenarios. As
an example of an open source environment, we use Bugzilla. In this context, we
also show how dependencies can be taken into account in utility-based
prioritization processes.
