There is now a world-wide trend towards the downsizing of information systems using a number techniques, such as clientserver architecture. Consequently, enterprise networks are fast growing in terms of size and functionality. These networks need to be managed effectively. Researchers have been working on the development of management solutions for enterprise networks, using recent advances in software engineering, communication protocols, and artificial intelligence techniques. However, not much work has been published on the role of human factors in the integrated management of networks and systems. This paper presents a new Cooperative management Methodology for Enterprise Networks (CoMEN), based on Computer Supported Cooperative Work (CSCW) techniques.
