Opportunities for Use and Development of Collaborative Tools in ATLAS

This document presents an assessment of the current and expected needs of the ATLAS Collaboration in the development, deployment, usage, and maintenance of collaborative tools to facilitate its internal and external communications, member training, education, and public outreach. It is prepared in response to a request by the ATLAS management to investigate these needs, to survey the current status, and to propose solutions where needed. We conclude the document with a set of recommendations designed to address selected immediate needs and to position the Collaboration for the anticipated growing demands for collaborative tools in a Grid-enabled analysis environment.
