The research on CSCW and groupware systems focus the activities of distributed teams involved in large projects by means of tools for communication and awareness. The activities of small collocated teams are often neglected. Analyzing preliminary requirements of small teams, it is possible to observe the need of tools to help the elaboration of project documentation. This paper presents a multi-agent system architecture to support software development in small collocated teams. The architecture proposed in this paper tackles the problem of elaborating documentation, by facilitating the elaboration of the Small Project Management Plan. Tools used in the software development are encapsulated by agents that extract and organize useful information for the elaboration of such a document.
