However, most of them do not support the conversion process of knowledge in an appropriate way. Specifically, they do not support brainstorming and creativity techniques, which are needed to convert tacit knowledge into explicit. This chapter presents how a wiki tool called the Spatial Hypertext Wiki (ShyWiki) can be used for supporting collaborative requirements elicita- tion following the knowledge creation spiral of Nonaka. The knowledge conversions in the spiral (socialization, externalization, combination, and internalization) and the knowledge types in each conversion are related to different activities in requirements elicitation, which can be performed through ShyWiki. ShyWiki allows stakeholders to collaborate by creating, brainstorming, structur- ing and reorganizing requirements contained in notes. In this way, the requirements negotiation and prioritization process can be done through the wiki pages which are seen as virtual boards that hold hypertext notes. INTRODUCTION Knowledge Management is composed of the activities, methods, processes, and software that validate, evaluate, integrate, and disseminate information for learning and decision making (Rhem, 2005). A Knowledge Management System (KMS) is an information system that improves the organizational process of creating, storing, retrieving, transferring, and applying knowledge (Leidner & Alavi, 2001).
