Where is the Border Between an Information System and a Knowledge Management System?

Both information systems and knowledgemanagement systems are im-portant in an organisation and often fulfil the same task. The aim of this paper is to identify the border between these two systems. The approach of the research is to analyse both systems in order to identify their role in an organisation, determine the problems, advantages, and opportu-nities, and discover common and uncommon features between them to find out when an information system becomes a knowledge man-agement system and when it is useful to implement the latter. Key words: information system, knowledge management system, information, knowledge and knowledge management jel Classification: m1, l86, c88
