For that purpose, it proposes a new, agile software and knowledge engineeringmethodology, called XP.K (eXtreme Programming of Kno systems). This is based on the four values simplicity, community, feedback,andcourage,andapplies object-oriented Round-Trip Engineering to knowledge modeling.The thesis is founded on the observation that for most knowledge-based systems, knowl-edge must necessarily be modeled evolutionary, in a close collaboration between domainexperts and engineers. The author argues that existing “heavy-weight” development meth-odologies from object-oriented Software Engineering and Knowledge Engineering are ofteninefficient, because they make changes in knowledge models too expensive.
