: One of the main challenges in distributed software development is the elicitation and management of knowledge regarding system requirements. Due to spatial distribution of involved parties, many limitations concerning interaction, communication, and conceptualization have to be faced. The SoftWiki project aims to provide an agile, wiki-based methodology to overcome these limitations in part. This paper introduces the SoftWiki approach and presents some of the tools that are developed to support knowledge sharing in distributed requirements engineering. 1 Motivation Knowledge-intensive activities in distributed software development such as requirements, configuration, and change management are not sufficiently covered by existing knowledge management solutions thus far [KT05]. Particularly in settings where knowledge is spread over diverse participants, established methodologies and tools mostly fail to adequately support collaboration. However, a consolidated conceptualization of the...
