Software maintenance, just like any other software engineering activity, is being conducted in an increasingly distributed manner by teams which are often virtual. This paper critically reviews existing models for Virtual Organisations, investigates issues affecting Distributed Software Maintenance Teams (DSMT) and proposes a model for selecting the appropriate Computer Supported Cooperative Work (CSCW) and Groupware tools and technologies in order to facilitate communication and resource allocation for DSMT. This model builds on current theories, classifications and major concepts in the area of CSCW and advances the way DSMT are perceived. This theoretical model is yet to be empirically evaluated and enriched so that it includes Workflow management systems.
