UTUCS is a system for supporting a group of people (an office, a team, etc.) interconnected through a communication network in handling conversations carried on through different communication media. It has been developed with the aim of providing a good coordination support system that pairs the best computer-based tool a group may have in any situation (dispersed versus non dispersed, synchronous versus non synchronous) with the ability to switch from one to another, maintaining integrated and linked the information it creates. As UTUCS is a general system devoted to integrating conversations independently of the communication media exploited, it has been designed in such a way that it can be enhanced by developing a module for any communication medium that can be effectively supported by a computer network. Up to now the Electronic Mail module, the Face to Face Couple Colloquies module, and the Face to Face Group Meetings module have been implemented.
