Many organizations are embarking upon knowledge management initiatives to enhance their competitiveness. While there has been a signi®cant amount of multidisciplinary research in this area, the evidence from surveys of practitioners indicate that a large proportion of company projects focus on the implementation of technology-based solutions without consideration of the structural and contextual issues. Many academic authors have presented a variety of different models for knowledge management but have often failed to relate these to the requirements of practitioners. This paper presents a model of knowledge management derived from a synthesis of current literature. The model emphasizes the need for knowledge evaluation within a knowledge management approach and describes, using a case study, how this might be achieved.
