In the paper the author discusses issues concerning the meaning of knowledge and its management in modern organisations. He first characterises, step by step, the life cycle of knowledge in an organisation then proceeds to discuss the meaning and tasks of knowledge of information systems and tools that improve knowledge management. Based on three levels of organisational management – strategic, tactical and operational – the author describes instruments and informatics solutions for improving knowledge acquisition and creation processes and the subsequent transfer of knowledge management in an organisation. Proper selection of systems supporting knowledge management can make it possible for users to create, distribute, search and have access to information and knowledge that can thereafter be used to benefit the organisation.
